Abstract:
A novel homogeneous calorimeter concept is being pursued by CalVision: a collaboration of multiple universities and national laboratories for the proposed high energy physics (HEP) Higgs factory. Dense, UV-transparent and cost-effective inorganic scintillators are required for a longitudinally segmented precision electromagnetic calorimeter (ECAL) with multiple readout. Novel heavy inorganic scintillators, if cost-effective enough, may also be used for a homogeneous hadronic calorimeter (HHCAL) concept which promises a jet mass resolution at a level of 20\%;/\sqrt{E}. We report an investigation on cerium-doped aluminoborosilicate (ABS) and cerium-doped DSB (BaO·2SiO2) glass samples. Optical and scintillation properties are characterized at room temperature, including X-ray excited emission, longitudinal and transverse transmittance, pulse height spectrum, light output, decay time, and light response uniformity for long samples. Their emission weighted quantum efficiency (QE) and photon detection efficiency (PDE) are calculated for photomultiplier (PMT) and silicon photomultiplier (SiPM) readouts respectively, and are compared to BGO, BSO and PWO crystals.
