DESCRIPTION
The μSPEC gamma-radiation micro spectrometer is a high performance device based on application of CdZnTe semiconductor detectors that operate at room temperature and MCA. The μSPEC allows measuring gamma-radiation spectra and storing it for processing in a PC through the USB port. In the spectrometer accepts three different detector modules equipped with quasi-hemispherical volumes of high quality CdZnTe of either 60 mm3, 500 mm3 or 1500 mm3.
The μSPEC is a fully self-sufficient device and consists of the detector, charge sensitive preamplifier, main amplifier, digital signals processor, high and low voltage power supplies and computer interface. It is powered from the computer USB.
