Description

The SRE3020 is a camera module for X-ray and gamma spectroscopy which can be used in a variety of applications, such as radiation hot-spot location, isotope identification, nuclear power plant monitoring, or compton scatter collimation. The module is mounted with a single cadmium zinc telluride (CZT) sensor with the dimensions of 20×20×15 mm$^3$. The sensor readout is pixelated, and it consists of array of 11×11 pixels (121 pixels in total). We present basic characterization of this assembly: (1) characterization of the readout electronics; (2) calibration procedure; (3) spectral response to various radionuclide and calibrated X-ray sources, and (4) fluence rate response of the camera. We also discuss the possibilities of using the setup as a Compton camera.
