The energy resolution of a LaBr(Ce) detector has been studied as a function of the count rate up to 340 kHz by using a 12bit 250 MS/s V1720 digitizer.

Abstract

The energy resolution of a LaBr(Ce) detector has been studied as a function of the count rate up to 340 kHz by using a 12bit 250 MS/s V1720 digitizer. The time resolution achieved by processing off line the digitized signals has been also determined. When results are compared with the ones obtained by using standard NIM electronics, it appears that the energy resolution obtained with the V1720 digitizer is better than the one with the NIM standard whereas the time resolution is poorer. However the time resolution by using the V1720 digitizer of about 1.2 ns [FWHM] seems to be sufficient for applications in Non-Destructive Analysis of large objects with tagged neutron beams.
