Incoherent bremsstrahlung in flat and bent crystal

TL;DR

This paper investigates incoherent bremsstrahlung in crystals, showing its dependence on crystal orientation and applying a simulation method to interpret recent experimental results at Mainz Microtron MAMI.

Contribution

It introduces a method for simulating incoherent bremsstrahlung in crystals and applies it to interpret experimental data, highlighting orientation effects.

Findings

Incoherent bremsstrahlung intensity varies with crystal orientation.

Simulation aligns well with experimental results.

Incoherent radiation spectrum resembles that in amorphous media.

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.
