A positron-sensitive surgical probe is being built based on a multi-anode PMT and a dual-layer detector, which consists of an 8 x 8 array of thin plastic scintillators and a matched GSO crystal array. Our probe uses three selection criteria to identify positrons and suppress background gammas, including annihilation 511 keV gammas. First an energy threshold was applied on the plastic signals; next a second energy threshold was applied on the PMT sum signal; finally, a coincidence techniquedoi:10.1109/nssmic.2001.1008408 fatcat:clgjc6qn4baidk4lexxtwi23ki
