“…Monte Carlo simulations were performed using the ITS one dimensional TIGERP Monte Carlo computer program 46,47 to calculate the absorbed energy deposition (AED) or the pulse height spectrum for energy deposition in the CsI (Tl) crystal. The AED gives the number of energy deposition events in an energy bin of width (E + ∆E) as a function of energy E. Simulations were performed for 28 different thickness combinations of CsI (Tl) and lead equivalent of leaded glass radiator (see Table 3-1).…”
