寻找νμ↔ντ振荡的实验--合唱热计的建造和组装已经完成。在实验中，量热计需要测量中微子相互作用产生的强子簇射的能量，分辨率为/∼30%/√E(GeV)。为了实现这一性能，在量热仪的最上游部分采用了近年来发展起来的将直径1 mm的闪烁纤维嵌入铅基体内的技术。剩下的部分使用了一种更传统的系统，即交替使用铅条和闪烁条。给出了模块结构的细节，以及模块暴露在电子束和µ子束下的结果。
The construction of modules and the assembly of the calorimeter for CHORUS, an experiment that searches forνμ↔ντoscillation, have been completed. Within the experiment, the calorimeter is required to measure the energy of hadronic showers produced in neutrino interactions with a resolution of /∼30%/√E(GeV). To achieve this performance, the technique, developed in recent years, of embedding scintillating fibers of 1 mm diameter into a lead matrix has been adopted for the most upstream part of the calorimeter. A more conventional system, of alternating layers of lead and scintillator strips, was used for the rest. Details of module construction as well as results obtained when modules were exposed to electron and muon beams are presented.
