摘要：

We describe a 24-element position-sensitive cylindrical NaI(Tl) detector which allows positron imaging with an on-axis position resolution of 3 cm FWHM and annihilation radiation energy resolution of 13% FWHM. Two such detectors will provide the trigger for the APEX experiment at Argonne National Laborarory, which is exploring anomalous positron and electron production observed in heavy-ion collisions.
