Gamma-Radiation CdZnTe Micro Spectrometer

μSPEC

Gamma-Radiation Micro spectrometer μSPEC is a very compact high performance device with changeable CdZnTe detection modules. The μSPEC is based on application of high-sensitivity room temperature operating CdZnTe semiconductor detectors and miniature multi channel analyser MikroMCA527 (GBS Elektronik GmbH). The μSPEC allows measurements of gamma-radiation spectra and storing it for processing in a PC via USB port. The changeable detection modules contain the high quality CdZnTe quasi-hemispherical detector of volume 60 mm3, 500 mm3 or 1500 mm3.

The μSPEC is a self-sufficient device and consists of the CdZnTe detector, charge sensitive preamplifier, main amplifier, digital signals processor, high and low voltages power supplies and computer interface. It is communicated and powered from the PC via USB port.

The μSPEC is operated and entirely compatible with the Windows based GBS MCA166/MCA527 WinSPEC software.
