Description

A. Artikov, A. Babayan, V. Baranov, J. Budagov, Yu.I Davydov, V. Glagolev, A. Hakobyan, H. Hakobyan, D.G. Hitlin, S. Miscetti, T. Mkrtchian, A. Simonenko, A. Sirunyan, A. Shalyugin, V. Tereschenko, H. Torosyan, Z. Usubov, H. Zohrabyan We report measurements of energy resolution of a 3x3 array made of 30x30x200 mm$^{3}$ undoped CsI crystals. The measurements have been performed using the electron beam of the linear accelerator of the Yerevan Physics Institute (Yerevan, Armenia) in the energy range of 15-35 MeV. The accelerator operated at extremely low beam intensity (10-50 electrons per second). That operation mode have been achieved by decreasing photo cathode temperature and lowering applied high voltage. The measured energy resolution is $\sigma_E $/E=6.4% at E=35 MeV. This resolution is dominated by the energy leakage due to the small dimensions of the prototype.
