Radiation Damage of F8 Lead Glass with 20 MeV Electrons

TL;DR

This study examines how 20 MeV electron radiation affects the optical transparency of F8 lead glass, revealing its susceptibility to radiation damage and comparing it to proton-induced damage.

Contribution

It provides the first detailed measurement of electron-induced radiation damage on F8 lead glass and compares it with proton damage effects.

Findings

F8 lead glass's transparency decreases with electron radiation dose

Electron damage is less severe than proton damage for the same dose

Optical attenuation length measurements quantify damage levels

Abstract

Using a 20 MeV linear accelerator, we investigate the effects of electromagnetic radiation on the optical transparency of F8 lead glass. Specifically, we measure the change in attenuation length as a function of radiation dose. Comparing our results to similar work that utilized a proton beam, we conclude that F8 lead glass is more susceptible to proton damage than electron damage.
