The PDS detector is composed of four actively shielded NaI(Tl)/CsI(Na) phoswich scintillators and has a field of view of 1.4 degrees (FWHM). The total geometric area is 795 cm/sup 2/. The authors present a description of the instrument and its development status with particular emphasis on the performance of the pulse shape analysis electronics.enconference paper10.1109/NSSMIC.1992.301366http://ieeexplore.ieee.org/xpls/abs_all.jsp?arnumber=30136654dcce078580fe1368eeae14
