Effect of Beam Dynamics Processes in the Low Energy Ring ThomX

TL;DR

This paper investigates how various beam dynamics processes affect beam quality and photon flux in the ThomX low energy ring, using extensive simulations to evaluate degradation and feedback system effectiveness.

Contribution

It provides a detailed simulation-based analysis of beam dynamics effects and feedback strategies in the ThomX ring, which is novel for this specific setup.

Findings

Compton scattering, intrabeam scattering, and coherent synchrotron radiation degrade photon flux.

Feedback systems can recover most of the flux lost due to beam dynamics effects.

Simulations of 400,000 turns demonstrate the impact of these processes.

Abstract

As part of the R\&D for the 50 MeV ThomX Compton source project, we have studied the effect of several beam dynamics processes on the evolution of the beam in the ring. The processes studied include among others Compton scattering, intrabeam scattering, coherent synchrotron radiation. We have performed extensive simulations of a full injection/extraction cycle (400000 turns). We show how each of these processes degrades the flux of photons produced and how a feedback system contributes to recovering most of the flux.
