Performance of a fine-sampling electromagnetic calorimeter prototype in the energy range from 1 to 19 GeV
Abstract
The fine-sampling electromagnetic calorimeter prototype has been experimentally tested using the 1-19 GeV/c tagged beams of negatively charged particles at the U70 accelerator at IHEP, Protvino. The energy resolution measured by electrons is DeltaE/E=2.8%/E + 1.3%. The position resolution for electrons is Deltax=3.1 + 15.4/sqrtE mm in the center of the cell. The lateral non-uniformity of the prototype energy response to electrons and MIPs has turned out to be negligible. Obtained experimental results are in a good agreement with Monte-Carlo simulations.
