Heating of a Thin Crystal Target at the Passage of High-Energy Short Electron Bunches

Abstract

A theoretical model is developed for the heating and deformation of a thin target at the passage of short electron bunches through it at the energies of modern free electron lasers, and the corresponding simulation is carried out. It is demonstrated that under these conditions, the target can undergo overheating or be irreversibly deformed, which makes it difficult to use such targets for the diagnostics of free electron beams used in modern lasers.
