Detection of low energy electrons by a total absorption Cherenkov spectrometer.

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.
