Deep Reinforcement Learning-based Longitudinal Optimization and Control of the Proton Synchrotron Booster at CERN / Kennedy, Lewis (University of Oxford (GB))
This thesis presents the development and implementation of algorithmic methods for au- tomated optimization software in the accelerator control room at CERN. Specifically, the problem of optimizing longitudinal profiles at PSB beam injection for improved luminosity in LHC-type beams is addressed using deep reinforcement learning methods. [...]

Development and Optimization of a Carbon-Nanotube Based Electron Gun / Welker, Elisabeth-Sena (Technische Universitaet Wien (AT))
Field emission (FE)‐based cathodes have become a promising alternative to thermionic sources, which suffer from high transverse energy spread and high power consumption. Here, a carbon‐nanotube (CNT)‐based electron gun was studied as a potential replacement for the thermionic gun currently used in the electron cooler of the Extra Low ENergy Antiproton (ELENA) decelerator at CERN. [...]

Impact of Measured Quadrupole Errors in the New Separation Dipoles on the HL-LHC Optics / Dilly, Joschua Werner (CERN) ; Maclean, Ewen Hamish (CERN) ; Tomas Garcia, Rogelio (CERN)
In this study the impact and correctability of the quadrupole field errors, as measured in the newly fabricated separation dipoles for the low-β∗ insertion regions of the HL-LHC, are evaluated. [...]

Transition Crossing by Means of Stable Islands / Wang, Sabrina
The phenomenom of transition energy crossing might generate adverse effects to the quality of charged-particle beams in circular accelerators that is hard to avoid, and has been known to introduce potentially adverse disturbance to the longitudinal dynamics of a beam of charged particles [...]
