为HERA的ZEUS探测器建造了一个具有特殊设计的电子读数的完全补偿铀闪烁体量热计。热量计的桶形部分和整个热量计的读出电子设备由美国合作建造。在1990年和1991年夏季的两个运行期间，其中一些模块在运往DESY安装之前在费米实验室进行了波束试验。这些测试主要是为了用电子和强子校准模块，测量细胞响应均匀性和分辨率。这些运行结果表明，使用介子和电子时，塔与塔之间和模与模之间的均匀性均优于1%，强子的能量分辨率为35%/√E，电子的能量分辨率为19%/√E，电子和强子的能量非线性均小于1%，电子和强子的绝对校准和响应相等性确认为2%。
A fully compensating uranium‐scintillator calorimeter with specially designed electronic readout was constructed for the ZEUS detector at HERA. The Barrel part of the calorimeter and the readout electronics for the entire calorimeter were built by the US collaboration. During two running periods in the summers of 1990 and 1991, some of these modules were subjected to beam tests at Fermilab before shipping to DESY for installation. These tests were primarily aimed at calibrating the modules with electrons and hadrons, measuring cell response uniformity and resolutions. Results from these runs show that tower‐to‐tower and module‐to‐module uniformities are better than 1% using both muon and electron, energy resolutions are 35%/ √E for hadrons and 19%/ √E for electrons, energy nonlinearity is less than 1% for both electron and hadron, the absolute calibration and the equality of response for electrons and hadrons are confirmed to 2%.
