Abstract
We report performance measurements of a sub-millimeter resolution CdZn Te strip detector developed as a prototype for astronomical instrument s. The prototype is a 1.4 mm thick, 64 x 64 stripe CdZnTe array with 0 .375 mm pitch in both dimensions. Pulse height spectra in orthogonal s tripe coincidence mode were recorded at several energies. The room-tem perature energy resolution is <10 keV (FWHM) for 122 keV photons with a peak-to-valley ratio >5:1. We also demonstrate spatial resolution ca pabilities finer than the stripe pitch.
