Method for the intrinsic calibration of CsI (Tl) detectors

摘要

A method for the intrinsic energy calibration of photomultiplier-coupled CsI (Tl) detectors is described. A simple empirical model of the scintillation light pulse-shape of CsI (Tl) crystals for light charged particles has been applied to simulate the particle identification matrix as it follows from the pulse-shape analysis method. The calibration procedure for the large-area CsI (Tl) detectors of the scintillator shell of the 4(pi)-array FOBOS for ions with Z<4 at energies below 100 AMeV is based on the energies of the particle punch-through points. 28 refs., 10 figs., 1 tab.
