Abstract
A prototype electromagnetic calorimeter for the KTeV experiment at Fermilab was tested at the CERN X1 beam-line. The calorimeter consisted of undoped cesium iodide crystals which were exposed to electrons, pions and muons. This test also featured a new digital readout system with 17 bits of dynamic range. The electron energy resolution is better than 1% at 5 GeV/c, and less than 0.5% at 60 GeV/c. The rejection factor for 40 GeV/c pions is estimated to be several hundred with 95% electron efficiency.
