Contribution of incoherent effects to the orientation dependence of bremsstrahlung from rapid electrons in crystal

TL;DR

This paper investigates how incoherent bremsstrahlung from relativistic electrons in crystals depends on crystal orientation, highlighting the role of incoherent effects and flux redistribution, supported by simulations and recent experimental data.

Contribution

It introduces a method to simulate incoherent bremsstrahlung in crystals and interprets experimental results, emphasizing the orientation dependence of incoherent radiation.

Findings

Incoherent bremsstrahlung intensity varies with crystal orientation.

Simulation aligns with recent experimental observations.

Incoherent effects significantly influence bremsstrahlung spectra.

Abstract

The bremsstrahlung cross section for relativistic electrons in a crystal is split into the sum of coherent and incoherent parts (the last is due to a thermal motion of atoms in the crystal). Although the spectrum of incoherent radiation in crystal is similar to one in amorphous medium, the incoherent radiation intensity could demonstrate substantial dependence on the crystal orientation due to the electrons' flux redistribution in the crystal. In the present paper we apply our method of the incoherent bremsstrahlung simulation developed earlier to interpretation of some recent experimental results obtained at the Mainz Microtron MAMI.
