CdZnTe semiconductor detector GR1
A small, lightweight, high-resolution semiconductor detector for gamma rays that can be used at room temperature, for quality inspection of radioactive drugs, nuclear physics research, and decommissioning.
The GR1 is a gamma-ray detector that uses a large-volume CdZnTe semiconductor detector measuring 10x10x10mm. It is compact and lightweight, approximately 25x25x63mm (60g), yet it is a complete gamma-ray spectrometer with an integrated 4k channel MCA. While the energy resolution (FWHM) of a typical NaI(Tl) scintillation detector is about 7%, the GR1 has a high energy discrimination capability of less than 2.5% (at 662 keV). Additionally, it does not require cooling to liquid nitrogen temperatures like Ge semiconductor detectors, making it ready for use at any time without incurring running costs. Operation is simple; you can start measuring immediately by connecting the GR1 to a PC (Windows 10 or higher) using a commercially available USB cable. A basic control program is provided free of charge. The GR1 can perform spectral measurements with excellent energy resolution even under high dose rates of approximately 1 mSv/hr.
