CsI calorimeter development for a high-precision, general-purpose detector for a Tau-Charm Factory

摘要

Design, fabrication techniques, and preliminary tests for a CsI calorimeter for the Tau-Charm Factory (TCF) proposed for construction in Spain are presented. Selected CsI calorimeter studies undertaken by the US Tau-Charm Collaboration, including simulations of machine-induced detector backgrounds in the CsI calorimeter, radiation change characterization of CsI(Tl) and CsI(Na) crystals from five manufacturers, crystal segmentation and photodiode/wavelength shifter readout schemes, and development of mechanical support structure, are reviewed. A test of a prototype CsI calorimeter conducted in the TRIUMF in M11 (120--400 MeV) and M13 (30--120 MeV) beamlines is discussed.
