Scintillating LXe/LKr electromagnetic calorimeter
- ITEP, Moscow (Russian Federation); and others
A scintillating LXe/LKr electromagnetic calorimeter has been built at the ITEP and tested at the BATES (MIT) accelerator. The detector consists of a PMT matrix and 45 light collecting cells made of aluminized Mylar partially covered with p-terphenyl as a wavelength-shifter (WLS). Each pyramidal cell has (2.1 x 2.1) x 40 x (4.15 x 4.15) cm dimensions and is viewed by an FEU-85 glass-window photomultiplier. The detector has been exposed to the 106--348 MeV electron beam. The energy resolution is {sigma}{sub E}/E {approx_equal} 5%/{radical}E at 100--350 MeV range in LXe; the coordinate resolution is {sigma}{sub X} {approx_equal} 0.7 cm; the time resolution is {sigma}{sub {tau}} {approx_equal} 0.6 ns for a single cell. Possible ways to improve energy resolution are discussed.
