Abstract

Monte Carlo simulations of the light collection for various tapered scintillator/photodiode configuration have been performed to find geometries that result in best light collection. From the simulation results, scintillators with the most favorable geometry, the conical frustrum, have been fabricated and evaluated. The response of a large conical frustum (top-2 inches, bottom-1 inches, 2 inches high) CsI(Tl) scintillator coupled with a 1 inches HgI2 PD is measured. The spectrum shows much higher detection efficiency than those from smaller scintillators, i.e., much higher peak-to-Compton ratio in the spectrum.
