Gamma-Radiation CdZnTe Micro Spectrometer

µSPEC

Gamma-Radiation CdZnTe Micro Spectrometer is a high performance device based on application of room temperature operating CdZnTe semiconductor detectors and a very small and low consuming digital multichannel analyzer (MCA) MicroMCA527 (GBS-Elektronik GmbH). The microspectrometer allows measuring gamma-radiation spectra and storing it for processing in a PC through the USB port. It is a self-sufficient device and consists of two modules - a base MCA module μSPEC/μSPEC+ and a replaceable detector module.

The base module contains an amplifier, a digital signal processor, a high voltage power supply of the detector, a low voltage power supply and computer interface.

Exchangeable detector modules contain a charge sensitive preamplifier and usually a high quality CdZnTe detector. There are detector modules with different CZT detector volumes from 5 mm3 to 1600 mm3. In addition, scintillation detector exchangeable modules are presented.

The microspectrometer is communicated and powered by a PC via USB port. It is made to operate under control of MS Windows based GBS WinSPEC for Inspectors free of charge software.

Clustered high efficiency gamma-radiation spectrometers

MultiSPEC

Clustered high efficiency gamma-radiation spectrometers MultiSPEC2000 / MultiSPEC6000 are based on application of the serial microspectrometers. It is an assembly of 4 serial microspectrometers combined by a special holder. All microspectrometers work in parallel, creating one common spectrum. For the collection and processing of the obtained spectra a special MS Windows based GBS software WinSPECx16 is used. Clustered spectrometer is communicated and powered by a PC via USB port. Spectrometers holder can be mounted on a mini tripod.
