GDS-100

CZT readout system for high resolution gamma-ray spectroscopy.

Product Description

The GDS-100 is a system made to read out CZT detectors. The system is based on an IDEAS readout ASIC with charge-sensitive preamplifier inputs for each CZT pixel and includes the necessary analog and digital electronics for controlling and performing the readouts.

The GDS-100 includes a digital core with pre-installed IDEAS firmware, a calibration circuit for charge injection, and is powered by a single 6 V supply, and controlled via Ethernet. High-voltage bias for the CZT detectors must be applied externally. The front-end is based around a readout ASIC from IDEAS with 121 charge-sensitive pre-amplifier inputs. Up to four front-ends can be inserted.

The system is delivered with a rudimentary PC software for control and data acquisition. An API is also included, letting the user design their own data acquisition software.
