350keV 40mm CZT Gamma Ray Detector Module
SRE4001-CZT40 SRE4001with 40mm CZT

The micro-IDM compact gamma ray detector module comes with a room temperature Cadmium-Zinc-Telluride (CZT) semi-conductor sensor with 256 pixels, arranged in a 16×16 matrix. Each pixel is connected to a channel with amplification and trigger circuitry implemented in application specific integrated circuits (ASICs).

The ASIC amplifies and samples the analog signal when the input signal is above a user programmable threshold. The trigger signal, the address of the triggered channel and the charge signal is then available at the at the output interface. The output self-resets after a predetermined time.

The SRE4001 allows for gamma ray energy measurements up to 350 keV. The module has been measured to with a Co-57 source and at room temperature. The Co-57 photo-peak at 122 keV has 5.4 keV full-width-half-maximum (FWHM) energy resolution.

The modules can be arranged to create gamma ray cameras of different geometries. Typical applications include arrays of SRE4001 modules, creating a larger imaging array. The module has two M2 threaded holes for mounting. The module has two electrical connectors, which allows for mounting on a carrier board.

The detector modules are insensitive to magnetic fields and can be operated in vacuum/space.

The module is also available with 25.4 mm x 25.4 mm CZT crystal: SRE4001-25.4, or without a crystal: SRE4001.

The SRE4001 is also available in a 700 keV-charge range version: SRE4001-CZT25.4

Carrier boards for multiple SRE4001 modules can be delivered, contact IDEAS for more information.
