Detection of low energy electrons by a total absorption Cherenkov spectrometer

TL;DR

This paper reports on the calibration of a total absorption Cherenkov spectrometer using a quasi-monochromatic electron beam, demonstrating its energy resolution across a broad energy range from 6 to 285 MeV.

Contribution

It provides the first detailed calibration results of a lead glass Cherenkov spectrometer for low energy electrons over a wide energy spectrum.

Findings

Energy resolution ranged from 89% at 6 MeV to 10% at 285 MeV.

Calibration was performed using a quasi-monochromatic electron beam.

The spectrometer is based on 14.8 X0 lead glass TF-1.

Abstract

Presented are results of calibration, with a quasi-monochromatic electron beam, of a total absorption Cherenkov spectrometer based on the 14.8 X0 lead glass TF-1. It was found that the energy resolution of the spectrometer was 89% to 10% in the energy range of the electron beam E = 6 to 285 MeV, respectively.
