用于费米实验室KTeV实验的原型电磁量热计在CERN X1束线上进行了测试。量热计由未掺杂的碘化铯晶体组成，这些晶体暴露在电子、介子和µ子中。这项测试还采用了一种新的数字读出系统，具有17位动态范围。电子能量分辨率在5GeV/c时优于1%，在60GeV/c时小于0.5%，对40GeV/c电子的拒绝因子估计为几百倍，电子效率为95%。
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.
