Contribution

It provides calibration coefficients for scintillation response of yttrium aluminum garnet crystals irradiated by monoenergetic electrons, with measurements from two different manufacturers.

Findings

Linear dependence of emission on electron beam charge

Isotropic photon emission observed

Calibration coefficients established for two crystals

Abstract

This paper presents the results of measurements of fluorescing cerium-doped yttrium aluminum garnet crystals after being irradiated by an accelerated electron beam with energy of around 4 MeV. The measurements were performed using the PHIL linear accelerator at LAL (France). We observe linear dependence of the crystal emission to the electron beam charge and the isotropy of the photon emission. We provide the calibration coefficients of the photon emission depending on the charge of the accelerated electron beam for two crystals originating from two different manufacturers.
