Vol. 48: Higher-Order-Mode-based Beam Phase and Beam Position Measurements in Superconducting Accelerating Cavities at the European XFEL

Liangliang Shi, PhD Thesis, 183 pages

I have designed and instrumented unconventional beam phase monitors based on monopole modes in TESLA cavities and demonstrated a routine resolution of 0.1° with a broadband setup.

Vol. 49: Predicting Heat Propagation in Roebel Cable-based Accelerator Magnet Prototype

Janne Ruuskanen, MSc Thesis, 64 pages

In this thesis, quench modelling of superconducting magnets is discussed. Moreover, a simulation tool was developed for quench simulations suitable for large superconducting devices. The tool utilizes a novel numerical approach to solve three-dimensional (3-D) heat diffusion in one-dimensional (1-D) modelling domain.

Vol. 50: Thermomechanical Response of Advanced Materials under Quasi-Instantaneous Heating

Federico Carra, PhD Thesis, 280 pages

This PhD thesis focuses on the latter scenario, where the heat deposition rate is high enough to lead to the origination of stress waves, propagating from the locally-heated zone to the surrounding of the structure, and superposing with the quasi-static stress field.

Vol. 51: Ultra-high vacuum characterization of advanced materials for future particle accelerators 

Carlotta Accettura, MSc Thesis, 142 pages

In order fully characterize the materials, different experimental set-ups were involved: one of the most important parts of the work was performed in vacuum test benches, where the outgassing rate value and the gas analysis of the materials have been evaluated.

Vol. 52: Electron Accelerators for Research, Industry and Environment − the INCT Perspective

Andrzej G. Chmielewski & Zbigniew Zimek (Editors), 236 pages

This book is a result of work carried out under the Horizon 2020 ARIES project and concerns the development of new technologies to ensure that future accelerators will be more affordable, reliable, sustainable and more effective. Considerations include energy efficiency, new accelerator conceptions, new high-temperature superconductors, new superconducting coatings and new materials for thermal management

Vol. 53: Coupling impendance and single beam collective effects for the Future Circular Collider

Eleonora Belli, PhD Thesis, 161 pages

By analyzing the structure of this mode, whose presence has been confirmed with CST simulations in the frequency domain, longitudinal slots and a water-cooled absorber were designed and included in the IR model to reduce the power loss and to prevent vacuum degradation.

Vol. 54: Beam Tests and Commissioning of Low Emittance Rings Proceedings

S. Casalbuoni, A.S. Müller & F. Zimmermann (Editors), Workshop Proceedings, 112 pages

The workshop “Beam Tests and Commissioning of Low Emittance Storage Rings” was held at the KIT Campus South in Karlsruhe from 18 to 20 February 2019. The workshop, organized under the auspices of the ICFA Beam Dynamics Panel, was part of ARIES Work Package 7, RULE, and co-supported by ARIES Work Package 6, APEC. A workshop focus was on beam tests and commissioning of low emittance rings such as MAXIV and SuperKEKB, as well as on preparation procedures, components and tests necessary for commissioning of the upcoming low emittance rings, like ESRF-EBS, SIRIUS, HEPS, ALS-U, PETRA-IV etc. Similarities and synergies with future circular colliders were evidenced. The present proceedings consist of summaries from the chairs of the seven workshop sessions, which are accompanied by individual contributions. 

Vol. 55: The 1st Workshop on Efficient Neutron Sources (ENS2019)

Y. Charles, D. Kiselev, A. Takibayev, M. Wohlmuther, L. Zanini (Editors), 94 pages

The first workshop on Efficient Neutron Sources, ENS2019, was held at the Paul Scherrer Institut (PSI) in Villigen, Switzerland, on 2-5 September 2019. The workshop, organized by PSI and ESS (European Spallation Source), was part of the Work Package 4: Efficient Energy Management of the ARIES program.  Neutron sources are used in various research fields, including condensed matter, fundamental physics, and medical applications. The workshop was dedicated to discuss the state-of-the-art and new ideas to design more efficient neutron sources. These proceedings consist of an introductory article summarizing the key points from the talks and from discussion sessions on the topical areas, followed by extended abstracts of the individual talks held by the participants. 

Vol. 56: Relevance of the irreversible degradation of superconducting Nb3Snwires and cables caused by transverse stress at room temperature within the FCC study at CERN

Patrick Ebermann, PhD Thesis, 109 pages

The objective of this thesis is to analyse the irreversible performance loss of the superconduc-tor caused by transverse compressive stress exerted at room temperatureduring magnet assembly,especially during the force-restraining procedure. First, a cable study was launched to obtain quantita-tive results of the degradation under conditions mimicking the real situation during magnet assembly. Additionally,  the degradation mechanism was investigated in detail on single wires.

Vol. 57: Analysis of a Novel Toroidal Configuration for Hadron Therapy Gantries

Enrico Felcini, PhD Thesis, 199 pages

GaToroid is a novel concept of toroidal gantry for hadron therapy. The operating principle of this configuration allows the delivery of clinical radiation doses from a discrete number of angles avoiding magnets as well as patient rotation. Large acceptance, fixed configuration and superconducting magnets offer an interesting reduction of size, weight and cost of the gantry and related infrastructures, creating an attractive alternative to the state of the art.

Vol. 58: Applications of Crystal Collimation to the CERN Large Hadron Collider (LHC) and its High Luminosity Upgrade Project (HL-LHC)

Marco D'Andrea, PhD Thesis, 144 pages

This PhD work details the main results of crystal collimation activities carried out at the CERN accelerator complex in 2018, with particular focus on tests with Pb ion beams at the LHC, which allowed to demonstrate the cleaning improvement provided by this collimation scheme. The code development effort aimed at improving the available simulation tools for crystal collimation with proton beams is also described, using applications beyond ion beam collimation explored at CERN as case studies.
