Anomalous beam diffusion near beam-beam synchrobetatron resonances

Physical Review Special Topics. Accelerators and Beams, 2012
The diffusion process near low order synchrobetatron resonances driven by beam-beam interactions at a crossing angle is investigated. Macroscopic observables such as beam emittance, lifetime, and beam profiles are calculated.

Compensation of the long-range beam-beam interactions as a path towards new configurations for the high luminosity LHC

Physical Review Special Topics. Accelerators and Beams, 2015
Colliding bunch trains in a circular collider demands a certain crossing angle in order to separate the two beams transversely after the collision. The magnitude of this crossing angle is a complicated function of the bunch charge, the number of long ...

Nonparaxial propagation of an intense relativistic electron beam through dense media

Physical Review Accelerators and Beams
An envelope equation is used to explore the propagation of a focused electron beam through dense conductive media like partially ionized high-pressure gas, metal vapor plumes from beam-target interactions, or low-density solid-phase targets.

An in-vivo treatment monitoring system for ion-beam radiotherapy based on 28 Timepix3 detectors

Scientific Reports
Ion-beam radiotherapy is an advanced cancer treatment modality offering steep dose gradients and a high biological effectiveness. These gradients make the therapy vulnerable to patient-setup and anatomical changes between treatment fractions, which may ...
