Incoherent horizontal emittance growth due to the interplay of beam-beam interaction and longitudinal wakefield in crab-waist colliders

Tatiana Pieloni, Mike Seidel, Péter Kicsiny

In this paper, we investigate incoherent quadrupolar synchrobetatron resonances caused by beam-beam collisions and their interplay with longitudinal wakefields in the context of crab-waist colliders. We present a comprehensive theoretical review of the est ...

Design of a Beam Separator for FLASH Electron Therapy Facilities

Mike Seidel

A promising modality of radiation therapy is FLASH: a technique in which the full radiation dose is delivered in just 1/10th of a second. This modality has been proven successful in destroying cancerous cells while sparing healthy tissues. The aim is to de ...

Accelerating Dynamic Aperture Evaluation Using Deep Neural Networks

Tatiana Pieloni, Mike Seidel, Davide Di Croce

The Dynamic Aperture is an important concept for the study of non-linear beam dynamics in a circular accelerator. The DA is defined as the extent of the phase-space region in which the particle's motion remains bounded over a finite number of turns. Such a ...
