Comparison between measured radiation levels and FLUKA simulations at CHARM and in the LHC tunnel of P1-5 within the R2E project in Run 2 / Prelipcean, Daniel
This thesis aims to benchmark the measured values of the radiation monitors employed at the European Organisation for Nuclear Research (CERN), focusing on the Large Hadron Collider (LHC), for Radiation to Electronics (R2E) applications with their simulated values using the FLUKA Monte Carlo code [...]

The IRRAD Data Manager (IDM) / Gkotse, Blerina (CERN ; U. PSL) ; Jouvelot, Pierre (U. PSL) ; Pezzullo, Giuseppe (CERN) ; Ravotti, Federico (CERN)
The Proton Irradiation Facility (IRRAD) is a reference facility at CERN for characterizing detectors and other accelerator components against radiation. To ensure reliable facility operations and smooth experimental data handling, a new IRRAD Data Manager (IDM) web application has been developed and first used during the last facility run before the CERN Long Shutdown 2.

Description of beam instabilities in synchrotrons with wakefields and space charge forces using the circulant matrix model / Buffat, X (CERN) ; Métral, E (CERN) ; Gottlob, E (Ecole Polytechnique, Lausanne ; U. Brussels (main)) ; Høgh, C (Ecole Polytechnique, Lausanne ; Imperial Coll., London) ; Oeftiger, A (Darmstadt, GSI ; CERN) ; Pieloni, T (Ecole Polytechnique, Lausanne)
A new model for the description of beam instabilities in synchrotrons featuring wakefields and space charge forces is proposed, using the circulant matrix approach. The predictions of this model are discussed in light of past ones, with a particular emphasis on the possible mitigation of the transverse mode coupling instability by space charge forces. [...]

Kalman filter-based longitudinal phase-space reconstruction method for hadron machines / Alves, Diogo (CERN) ; Lasocha, Kacper (CERN)
This work proposes a novel longitudinal phase-space reconstruction method for hadron machines. The proposed method is based on a Kalman filter and can therefore provide real-time estimates of the phase-space reconstruction. [...]

High-Temperature Superconductor Coatings for Beam Impedance Reduction in Particle Colliders: Nonlinear Effects / Calatroni, Sergio (CERN) ; Vaglio, Ruggero (CNR-SPIN, Naples ; INFN, Naples)
Coating of surfaces facing particle beams with hightemperature superconductors (HTS) for reducing the beam coupling impedance is being considered for the next generation of hadron colliders, such as the FCC-hh at CERN, where HTS would be exposed to the high-frequency wakefields generated by the particle bunches and to the strong field of the steering magnets. In this frame, we present a simple model for the calculation of the microwave response of HTS exposed to a strong external magnetic field, which takes into account the nonlinearity of the pinning potential of the vortex lattice.
