Longitudinal uniformity, time performances and irradiation test of pure CsI crystals

F centre production in CsI and CsI ± Tl crystals under Kr ion irradiation at 15

We present results of simultaneous in situ luminescence and optical absorption studies in scintillator CsI and CsI±Tl crystals, exposed to very dense electronic excitations induced by Kr ions (8.63 MeV/amu). Irradiation at 15 K leads to the formation of the prominent F absorption band. In addition, several other features of the broad absorption between exciton and F bands were ascribed to an an...

Growth of CsI(Tl) crystals doped with Ca and Tm and investigation of its scintillation characteristics

In this work, the growth of CsI(Tl) crystals as gamma detector was performed using vertical Bridgman method with Ca and Tm co-dopants. For evaluation of the growth crystals, X-Ray Diffraction (XRD), photoluminescence and thermoluminescence spectra as well as recorded gamma spectra were employed. In addition, the scintillation properties including energy resolution, scintillation decay time, abs...

Light response of pure CsI calorimeter crystals painted with wavelength - shifting lacquer

We have measured scintillation properties of pure CsI crystals used in the shower calorimeter built for a precise determination of the π→πeνe decay rate at the Paul Scherrer Institute (PSI). All 240 individual crystals painted with a special wavelength-shifting solution were examined in a custom-build detection apparatus (RASTA—radioactive source tomography apparatus) that uses a 137Cs radioact...
