Abstract :
A scintillating LXe/LKr electromagnetic calorimeter has been built at the ITEP and tested at the BATES (MIT) accelerator. The detector consists of PMT matrix and 45 light collecting cells made of aluminized 50 microns Mylar partially covered with p-terphenyle as a wavelength-shifter (WLS). Each pyramidal cell has (2.1×2.1)×40×(4.15×4.15) cm dimensions and is viewed by FEU-85 glass-window photomultiplier. The detector has been exposed at 106-348 MeV electron beam. The energy resolution σE/E≅5%/√E at 100-350 MeV range in LXe, the coordinate resolution σx≅0.7, the time resolution σt≅0.6 ns for single cell have been obtained. Possible ways to improve energy resolution are discussed
