Summary

enlarge

Block diagram of the ASIC, including three front-end channels, two for amplification of the two grid signals (collecting and non-collecting) and one for amplification and processing of the cathode signal.

This invention offers an Application Specific Integrated Circuit (ASIC) for Cadmium Zinc Telluride Co-Planar grid (CPG) sensor. This ASIC is capable of amplifying and suitable processing signals from CPG sensors and therefore is attractive for building portable and battery-operated detection systems.

Description

Describes a method for measuring a depth of interaction of an ionizing event using a co-planar collecting electrode and a non-collecting electrode. The method comprises of obtaining a difference in time between a time of occurrence of an ionizing event as detected by one of the collecting electrode and the non-collecting electrode and a time of detection of a charge generated by the ionizing event at the collecting electrode and using this to calculate the depth of interaction of the ionizing event.
