Study of Signal Shaping and Energy Repsonse of Large NaI(Tl) Spectrometers for Application at NAL

PDF Version Also Available for Download.

Description

Signal shaping properties are demonstrated with a large NaI(Tl) crystal assembly, 20 in. thick and 30 in. in diameter. Correlated energy resolution responses are shown for total energy absorption in the crystal from 580 MeV electrons. Light collection optics by diffuse reflection most likely determined the 10% to 90% rise-time of signals of 80 nsec, connected with the transit time of trapped light, before it reaches a photocathode surface. Using a signal clipping technique, the trailing edge of pulses are shaped to have base-lines entirely restored to zero. Providing good energy resolution, signals are obtained which are shaped to have ... continued below

Description

Signal shaping properties are demonstrated with a large NaI(Tl) crystal assembly, 20 in. thick and 30 in. in diameter. Correlated energy resolution responses are shown for total energy absorption in the crystal from 580 MeV electrons. Light collection optics by diffuse reflection most likely determined the 10% to 90% rise-time of signals of 80 nsec, connected with the transit time of trapped light, before it reaches a photocathode surface. Using a signal clipping technique, the trailing edge of pulses are shaped to have base-lines entirely restored to zero. Providing good energy resolution, signals are obtained which are shaped to have 200 nsec full-width at base. The energy resolution responses from signal pulse-height measurement are demonstrated. Further improvements to obtain shorter pulse-widths are discussed and the capability of these crystals to handle several types of background is shown.
