There has been a great deal of interest in the use of LaBr3 (Ce) detectors for fast
timing measurements. Due to their excellent energy resolution, ≈ 3% at 1MeV,
they offer an improved signal to background over BaF2 which has ≈ 9% energy
resolution. Many groups are planning arrays of LaBr3 detectors. The 8π collaboration has recently acquired a small array of 6 2”x 2” cylindrical LaBr3 detectors to replace its BaF2 detectors. We have been investigating the effects of detector-to-detector scattering on timing resolution. We have further investigated the use of Compton-suppression shields with LaBr3 detectors. This will also be the first testing of the DANTE acquisition system in the 8π. A summary of the results of our optimization, scattering studies, and Compton-suppression tests will be presented.
