  abstract = {There are correctors in the insertion regions (IRs) of the LHC, known as MCX, which could be misaligned in the transversal plane by up to about 1 mm. This could cause several unwanted effects such as {$\beta$}-beating and increased amplitude detuning. The High Luminosity LHC (HL-LHC) upgrade will introduce many changes to the accelerator lattice, and will depend on even lower values of {$\beta{_\ast}$}. The effects of MCX misalignments are therefore studied for both LHC and HL-LHC.},

  abstract = {Brightness is an important parameter for any synchrotron radiation source. Correcting the emittance coupling is one of the ways to increase photon beam brightness in the operational storage ring. The main source of this effect is betatron coupling, resulting from the skew quadrupolar errors. Tune split and Linear Optics from Closed Orbit (LOCO) techniques are used to measure the betatron coupling. We discuss the measurement result of betatron coupling and its correction in the Indus-2 storage ring using available four power supplies, as the knobs, driving the skew quadrupole windings located on sextupoles. The measured coupling ratio of {$\sim$}0.8\% closely matches with the coupling ratio obtained from the LOCO fit model. Based on LOCO correction, the coupling ratio can be reduced to {$\sim$}0.4\%, which is limited by the degrees of freedom and not by the field strengths. To achieve a smaller and controlled value of coupling, simulation studies based on the LOCO fit model and using the multi-objective differential evolution algorithm with more skew quadrupole power supplies are performed in Indus-2. With sixteen independent power supplies, the emittance ratio can be reduced to {$<$}0.04\% and the brightness enhances by an order of magnitude. Besides, the optimization method used provides quantitative trade-offs between coupling related parameters such as beam tilt angle, emittance ratio, vertical emittance, and vertical beam size, and desired values can be chosen from the Pareto optimal front.},

  abstract = {In order to obtain the necessary luminosity with a reasonable amount of beam power, the Compact LInear Collider (CLIC) design includes an unprecedented collision beam size of {$\sigma$}y=1 nm vertically and {$\sigma$}x=45 nm horizontally. With exceptionally small and flat beams, the luminosity can be significantly degraded due to the combination of the experimental solenoid field and a large crossing angle. The two main effects reducing the luminosity are y-x{${'}$}-coupling and an increase of vertical dispersion. Additionally, incoherent synchrotron radiation (ISR) from the orbit deflection created by the solenoid field increases the beam emittance and results in unrecoverable luminosity degradation. A novel approach to evaluate the ISR effect from a realistic solenoid field without knowledge of the full compensation of the geometric aberrations is presented. This approach is confirmed by a detailed study of the correction techniques to compensate the beam optics distortions. The unrecoverable luminosity loss due to ISR for CLIC at 3 TeV has been evaluated, and found to be around 4\% to 5\% for the solenoid design under study.},

Following the tendency to reduce dependence on the configuration of the preceding proton run, a completely new optics cycle with the strongest ever focussing at the ALICE and LHCb experiments was designed and rapidly implemented, demonstrating the maturity of the collider's operating modes. Beam-loss monitor thresholds were carefully adjusted to provide optimal protection from the multiple loss mechanisms in heavy-ion operation. A switch from a basic bunch-spacing of 100 ns to 75 ns was made as the beam became available from the injector chain. A new record luminosity, 6 times the original design and close to the operating value proposed for HL-LHC, provided validation of the strategy for mitigating quenches due to bound-free pair production (BFPP) at the interaction points of the ATLAS and CMS experiments. Most of the beam parameters of the HL-LHC Pb-Pb upgrade were attained during this run and the integrated luminosity goals for the first 10 years of LHC operation were substantially exceeded.},

Some critical aspects of the feasibility of partial or full energy upgrades are studied here, together with novel mitigation measures. Higher beam energies can be realized by pushing the installed main dipoles to their limits or by replacing different fractions of installed magnets. Moreover, a revised lattice design for a full energy upgrade, also known as the high-energy LHC (HE-LHC), is presented. The studies reported focus on the linear optics design and on the lattice layout. In particular, an optics with 60\textdegree{} transverse phase advance in the regular arc cells, meant to alleviate the strength requirements for the main quadrupoles, has been designed in view of possible beam tests during the next LHC run 3. The methods developed in this article, for matching the ring geometry to a reference tunnel, for improving the beam aperture, and for minimizing the required field strengths for new high-energy LHC-like machines, will also be applicable to other future circular collider projects.},

  abstract = {Several transverse noise sources, such as power supply ripples, can potentially act as an important limiting mechanism for the luminosity production of the Large Hadron Collider (LHC) and its future High-Luminosity upgrade (HL-LHC). In the presence of non-linearities, depending on the spectral components of the power supply noise and the nature of the source, such a mechanism can increase the diffusion of the particles in the distribution through the excitation of sideband resonances in the vicinity of the ones driven by the lattice non-linearities. For the HL-LHC, due to the reduction of the beam size in the Interaction Points (IP) of the high luminosity experiments (IP1 and 5), increased sensitivity to noise effects is anticipated for the quadrupoles of the inner triplets. The modulation that may arise from the power supply ripples will be combined with the tune modulation that intrinsically emerges from the coupling of the transverse and longitudinal plane for off-momentum particles through chromaticity. To this end, the aim of this paper is to study the impact of tune modulation effects on the transverse beam motion resulting from the interplay between quadrupolar power supply ripples and synchro-betatron coupling. A power supply noise threshold for acceptable performance is estimated with single-particle tracking simulations by investigating the impact of different modulation frequencies and amplitudes on the Dynamic Aperture. The excitation of sideband resonances due to the modulation is demonstrated with frequency maps and the higher sensitivity to specific modulation frequencies is explained. Finally, a power supply noise spectrum consisting of several tones is considered in the simulations to determine whether the presence of power supply ripples in the quadrupoles of the inner triplet will limit the luminosity production in the HL-LHC era.},

  abstract = {Main scientific goal of the NICA/MPD project (Nuclotron-based Ion Collider fAcility/ Multi Purpose Detector) under construction at JINR (Dubna) is exploration of the phase diagram of strongly interacting matter in the region of high compression. The planned experimental program includes studies of possible signs of the phase transitions and critical phenomena in heavy ion (up to Au) collisions at the center-of-mass energies up to 11 GeV/u. The collider experiment provides optimum conditions for efficient energy scan measurements. Attainment of the required average luminosity of the order of 1027 cm-2{$\cdot$}s-1 for such physics experiment faces several accelerator physics and technology challenges. Contrary to high energy colliders, the luminosity of NICA case will be mostly limited by the Laslett tune shift, while the beam-beam tune shift parameter will be negligibly small. Flexible operational procedures for the beam storage and short bunch formation have been developed to provide maximum peak luminosity over wide energy range. Beam cooling is critical to counteract luminosity decay due to intra-beam scattering. NICA collider design addresses these issues and satisfies all the requirements for the colliding beams experiments.},

Several measurement techniques for optics functions are used in the LHC to provide the most suitable method for a given scenario. A new tool to run k-modulation measurements and analysis is being developed with the aim to be fully automatic and online. It will take constraints of various systems such as tune measurement precision, powering limits of the LHC superconducting circuits and limits of their quench protection systems into account. It will also provide the possibility to sinusoidally modulate the currents of the investigated quadrupoles with a predefined frequency and amplitude to increase the measurement precision further. This paper will review the advantages and limitations of k-modulation measurements in the LHC with and without sinusoidal current modulation. The used algorithms and tools will be presented and estimates on the obtainable beta function measurement precision will be given.},

  abstract = {The Large Hadron Collider (LHC) is currently the world's largest particle accelerator with the highest center of mass energy in particle collision experiments. The control of the particle beam focusing is essential for the performance reach of such an accelerator. For the characterization of the focusing properties at the LHC, turn-by-turn beam position data is simultaneously recorded at numerous measurement devices (BPMs) along the accelerator, while an oscillation is excited on the beam. A novel analysis method for these measurements (\$N\$-BPM method) is developed here, which is based on a detailed analysis of systematic and statistical error sources and their correlations. It has been applied during the commissioning of the LHC for operation at an unprecedented energy of 6.5 TeV. In this process a stronger focusing than its design specifications has been achieved. This results in smaller transverse beam sizes at the collision points and allows for a higher rate of particle collisions. For the derivation of the focusing parameters at many synchrotron light sources, the change of the beam orbit is observed, which is induced by deliberate changes of magnetic fields (orbit response matrix). In contrast, the analysis of turn-by-turn beam position measurements is for many of these machines less precise due to the distance between two BPMs. The \$N\$-BPM method overcomes this limitation by allowing to include the measurement data from more BPMs in the analysis. It has been applied at the ALBA synchrotron light source and compared to the orbit response method. The significantly faster measurement with the \$N\$-BPM method is a considerable advantage in this case.  Finally, an outlook is given to the challenges which lie ahead for the control of the beam focusing at the HL-LHC, which is a future major upgrade of the LHC.},

  abstract = {The beam interruptions (interlocks) of particle accelerators, despite being necessary safety measures, lead to abrupt operational changes and a substantial loss of beam time. A novel time series classification approach is applied to decrease beam time loss in the High Intensity Proton Accelerator complex by forecasting interlock events. The forecasting is performed through binary classification of windows of multivariate time series. The time series are transformed into Recurrence Plots which are then classified by a Convolutional Neural Network, which not only captures the inner structure of the time series but also utilizes the advances of image classification techniques. Our best performing interlock-to-stable classifier reaches an Area under the ROC Curve value of \$0.71 \textbackslash pm 0.01\$ compared to \$0.65 \textbackslash pm 0.01\$ of a Random Forest model, and it can potentially reduce the beam time loss by \$0.5 \textbackslash pm 0.2\$ seconds per interlock.},

This paper proposes a fundamentally different model-based method that explicitly isolates anomalies instead of profiles normal points. To our best knowledge, the concept of isolation has not been explored in current literature. The use of isolation enables the proposed method, iForest, to exploit sub-sampling to an extent that is not feasible in existing methods, creating an algorithm which has a linear time complexity with a low constant and a low memory requirement. Our empirical evaluation shows that iForest performs favourably to ORCA, a near-linear time complexity distance-based method, LOF and Random Forests in terms of AUC and processing time, and especially in large data sets. iForest also works well in high dimensional problems which have a large number of irrelevant attributes, and in situations where training set does not contain any anomalies.},

This was prompted by a need to extend the scope of beam-based commissioning at high-energy, beyond the exclusively linear realm considered previously, and into the nonlinear regime. It also stemmed from a recognition that, due to operation with crossing angles in the experimental insertions, the linear and nonlinear optics quality were intrinsically linked through potentially significant feed-down at these locations. Following the usual linear optics commissioning therefore, corrections for (normal and skew) sextupole and (normal and skew) octupole errors in the high-luminosity insertions were implemented. For the first time, the LHC now operates at top-energy with beam-based corrections for nonlinear dynamics, and for the effect of the crossing-scheme on beta-beating and dispersion. The new commissioning procedure has improved the control of various linear and nonlinear characteristics of the LHC, yielding clear operational benefits. This report gives a detailed account of the beam-based measurements carried out during the experimental campaigns},

  abstract = {Nonlinear magnetic errors in low-{$\beta$} insertions can contribute significantly to detuning with amplitude, linear and nonlinear chromaticity, and lead to degradation of dynamic aperture and beam lifetime. As such, the correction of nonlinear errors in the experimental insertions of colliders can be of critical significance for successful operation. This is expected to be of particular relevance to the LHC's second run and its high luminosity upgrade, as well as to future colliders such as the Future Circular Collider. Current correction strategies envisioned for these colliders assume it will be possible to calculate optimized local corrections through the insertions, using a magnetic model of the errors. This paper shows however, that reliance purely upon magnetic measurements of the nonlinear errors of insertion elements is insufficient to guarantee a good correction quality in the relevant low-{$\beta$}* regime. It is possible to perform beam-based examination of nonlinear magnetic errors via the feed-down to readily observed beam properties upon application of closed orbit bumps, and methods based upon feed-down to tune have been utilized at RHIC, SIS18, and SPS. This paper demonstrates the extension of such methodology to include direct observation of feed-down to linear coupling in the LHC. It is further shown that such beam-based studies can be used to complement magnetic measurements performed during LHC construction, in order to validate and refine the magnetic model of the collider. Results from first attempts of the measurement and correction of nonlinear errors in the LHC experimental insertions are presented. Several discrepancies of beam-based studies with respect to the LHC magnetic model are reported.},

Nonlinear dynamics was already well mastered, e.g., in the close field of celestial mechanics as similar problems had been considered and successfully tackled. Hence, several results were available to aid comprehension of the behavior of charged particle beams under the influence of nonlinear forces. Here, we discuss how concepts derived from the theory of dynamical systems, linked with the fundamental Kolmogorov\textendash Arnold\textendash Moser theory and Nekhoroshev theorem, can be successfully applied to the analysis of nonlinear motion of charged particles in a circular accelerator. Based on these ideas, an innovative method to measure the extent of the phase-space region within which bounded motion occurs is presented, which has been successfully tested for the first time at the CERN LHC.},

  abstract = {The nonlinear dynamics of a circular accelerator such as the Large Hadron Collider (LHC) may significantly impact its performance. As the LHC progresses to more challenging regimes of operation it is to be expected that the nonlinear single particle dynamics in the transverse planes will play an increasing role in limiting the reach of the accelerator. As such it is vital that the nonlinear sources are well understood. The nonlinear fields of a circular accelerator may be probed through measurement of the amplitude detuning: the variation of tune with single particle emittance. This quantity may be assessed experimentally by exciting the beam to large amplitudes with kicks, and obtaining the tunes and actions from turn-by-turn data at Beam Position Monitors. The large amplitude excitations inherent to such a measurement also facilitate measurement of the dynamic aperture from an analysis of beam losses following the kicks. In 2012 these measurements were performed on the LHC Beam 2 at injection energy (450 GeV) with the nominal magnetic configuration. Nonlinear coupling was also observed. A second set of measurements were performed following the application of corrections for b4 and b5 errors. Analysis of the experimental results, and a comparison to simulation are presented herein.},

The regular injections required by the MD also represented an opportunity to test a new coupling feedback routine based on the analysis of injection oscillation data. Initial measurements were performed on the nominal state of the LHC at injection. On completion of this study the Landau octupoles were turned off and corrections for higher-order chromaticities were implemented to reduce the non-linearity of the machine as far as possible. A second set of measurements were then performed. All studies were performed using the LHC aperture kicker (MKA).},

  abstract = {So far, the LHC has operated without any dedicated commissioning of the nonlinear optics at top energy. As {$\beta{_\ast}$} is reduced however, the impact of nonlinear errors in experimental insertions may become sizable. Below {$\beta{_\ast}$} = 0.8 m, and in particular with possible LHC configurations approaching 0.3 m, an operational impact from uncompensated nonlinear errors in the IRs is to be expected. Notably the contribution of normal octupole errors in IR1 and IR5 to the tune footprint becomes comparable to that created by the Landau octupoles, with implications for the performance of instrumentation and Landau damping of instabilities. In the HL-LHC compensation of IR-nonlinear sources may become a critical issue, with feed-down from IR-sextupole errors having the potential to generate substantial linear optics perturbations. This effect will require an evolution of the linear optics commissioning strategy in the LHC and HL-LHC. Current understanding of the impact of these errors and our ability to correct them will be reported. Nonlinear optics commissioning activities undertaken elsewhere in the machine cycle will also be introduced.},

Indeed, correction of sextupole and octupole magnetic errors in LHC experimental insertions has yielded clear operational benefits in recent years. Numerous studies predict, however, that even correction of nonlinearitites up to dodecapole order will be required to ensure successful exploitation of the HL-LHC. It was envisaged during HL-LHC design that compensation of high-order errors would be based upon correction of specific resonances, as determined from magnetic measurements during construction. Experience at the LHC demonstrated that beam-based measurement and correction of the sextupole and octupole errors was an essential complement to this strategy. As such, significant interest also exists regarding the practicality of beam-based observables of multipoles up to dodecapole order. Based on experience during the LHC's second operational run, the viability of beam-based observables relevant to dodecapole order errors in the experimental insertions of the HL-LHC are assessed and discussed in detail in this paper.},

  abstract = {Physicists use self-written software as a tool to fulfill their tasks and often the developed software is used for several years or even decades. If a software product lives for a long time, it has to be changed and adapted to external influences. This implies that the source code has to be read, understood and modified. The same applies to the software of the Optics Measurements and Corrections (OMC) team at CERN. Their task is to track, analyze and correct the beams in the LHC and other accelerators. To solve this task, they revert to a self-written software base with more than 150,000 physical lines of code. The base is subject to continuous changes as well. Their software does its job and is effective, but runs regrettably not efficient because some parts of the source code are in a bad shape and has a low quality. The implementation could be faster and more memory efficient. In addition it is difficult to read and understand the code. Source code files and functions are too big and identifiers do not reveal the intention of the coder and are meaningless or even misleading. Thus it isn't easy to modify and extend the code. However, this is also a common problem in software engineering. The improving of productivity and quality in software development is still a field of research. This thesis is about the improvement of the software quality in the OMC team by adopting several techniques from professional software development. A more professional development environment was created and the quality of the existing software base was improved. Further, the members of the OMC team were sensitized to write directly clean code, to practice pair programming and to review each others source code. To measure software quality, a tailored quality model was defined. Code modifications trigger automatically an analysis tool to create metrics, based on the quality model, and present them in a dashboard. A trend anaylysis of this data will show if future developments will increase the software quality. In case that it becomes worse, appropriate steps can be initiated to refactor the corresponding source code parts. In addition a best practices guide was developed in the course of this thesis, which can be used to improve the software quality in any other team.},

  abstract = {Precise control of beam optics and beam stability is of critical importance for machine protection and performance of today's high-energy particle accelerators. For the next generation of accelerators, the tolerances are even tighter.  This thesis presents new methods and improved techniques to efficiently identify, measure and correct a range of errors in particle accelerators. Circular and linear accelerators have been studied in parallel.  The Circular Large Hadron Collider (LHC) collides mostly protons at energies of 6.5 TeV and European Synchrotron Radiation Facility (ESRF) storage ring accelerates electrons to produce synchrotron light. The Compact Linear Collider (CLIC) will provide electron-positron collisions at centre of mass energies up to 3 TeV. In CLIC, a non-colliding beam, referred to as drive beam, generates RF power to accelerate the main beam. LHC's optics measurement scheme was improved, also by studying ESRF. This resulted in significantly improved \$\textbackslash beta\$-function  measurement, achieving twice the best-documented precision so far.  The optics correction algorithm was improved allowing \$\textbackslash beta\$-beating in the LHC to systematically reach a level below 1.8\% rms.  An adiabatic simultaneous 3-dimensional beam excitation, which combines AC-dipoles  with RF-frequency modulation, significantly sped up beam optics measurements.  The analysis of beam frequency spectra from turn-by-turn data was also made   significantly faster, in the LHC by a factor \$\textbackslash sim 300\$. These results contributed to LHC's excellent performance beyond its designed targets.  They also contributed towards its upgrade the High Luminosity LHC.  CLIC has stringent requirements on drive beam stability in terms of beam current, energy and phase. In the CLIC Test Facility 3 (CTF3), a novel algorithm to identify drifts and correlations was developed and applied in a study of drive beam stabilisation. The underlying causes of drifts were found and multiple beam-based feedbacks were developed and commissioned in CTF3, in this way achieving the stability goals. These improvements therefore played a key role in demonstrating the viability of CLIC in terms of drive beam stability.},
