Electron beam dynamics with and without Compton back scattering
type: Dataset
description: This thesis introduce my work on transverse and longitudinal non linear dynamics of an electron beam in ThomX, a novel X-ray source based on Compton backscattering. In this work I implemented in simulation code theoretical models to calculate transverse and longitudinal non linear dynamics under Compton back scattering. The processes studied include collective effect such as longitudinal space charge, resistive wall and coherent synchrotron radiation, intra beam scattering. I also implemented a longitudinal feedback algorithm and studied the effect of the feedback’s delay in the simulation to explore its effects on beam dynamics. This code allows to perform a full 6D simulation of the beam dynamics in a ring under Compton back scattering taking into account the feedback stabilisation for the 400 000 turns (~ 20 ms) of one injection cycle. One important feature is that this simulation code can be run on a computer farm. Using this code I investigated the electrons dynamics in ThomX and the flux of scattered Compton photons. I analysed the relative contribution of each physical phenomena to the overall beam dynamics and how to mitigate their disruptive effect. As part of my work on longitudinal phase feedback I also measured and analysed properties of the ELETTRA RF cavity to be used on ThomX.
