Abstract

We have implemented a capacitive charge-division readout for a germanium 5×5 orthogonal strip detector. We present measurements of non-linearity, and of energy and position resolution as a function of energy (60 and 662 keV) and of network capacitance. Energy and position non-linearities, which are worse for low capacitance networks, appear in the response along the charge division network, as well as along the length of each detector strip. The nonlinearities can be corrected by using an independent gain calibration for each pixel, allowing for use of a lower capacitance charge division network which provides better position resolution
