Title: Coplanar interdigitated grid detector with single electrode readout

Abstract

The coplanar interdigitated grid technique with single electrode readout provides substantial spectral performance improvement over that of conventional full-area planar electrode detectors and over coplanar interdigitated grid detectors which measure the difference between the induced charge signals from two interdigitated coplanar grid electrodes. The signal from only one interdigitated grid electrode is read out. The signal response is optimized by changing the relative areas of the two grid electrodes and the bias applied across the detector. Only one preamplifier is needed and signal subtraction is not necessary. This eliminates the electronic noise contribution from the additional preamplifier used in the normal coplanar grid implementation, and conventional single-amplifier detector electronics can be used.
