Channeling and Radiation of 855 MeV Electrons and Positrons in Straight and Bent Tungsten (110) Crystals

TL;DR

This paper simulates the behavior of 855 MeV electrons and positrons in straight and bent tungsten (110) crystals, analyzing channeling, dechanneling, and radiation emission, and compares results with other materials and theories.

Contribution

It introduces detailed simulations of electron and positron channeling in tungsten crystals using the extMBNExplorer software, including bent configurations and spectral radiation analysis.

Findings

Channel acceptance and dechanneling lengths vary with bending radius.

Spectral distribution of emitted radiation differs between straight and bent crystals.

Results align with or extend existing theories and data for other crystal materials.

Abstract

Planar channeling of 855 MeV electrons and positrons in straight and bent tungsten (110) crystal is simulated by means of the \MBNExplorer software package. The results of simulations for a broad range of bending radii are analyzed in terms of the channel acceptance, dechanneling length, and spectral distribution of the emitted radiation. Comparison of the results with predictions of other theories as well as with the data for (110) oriented diamond, silicon and germanium crystals is carried out.
