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.
