Product Introduction :
RJ46 Gamma Spectrometry Systems with HPGe Detector mainly includes a new type of high-purity germanium low-background spectrometer independently developed. The spectrometer adopts a particle event readout method, and uses digital multi-channel to obtain and store the energy (amplitude) and time information of the HPGe detector output signal.
System composition:
The RJ46 Gamma Spectrometry Systems measurement system is mainly composed of three parts: high-purity germanium detector, multi-channel signal processor, and lead chamber. The detector array includes the HPGe main detector, digital multi-channel pulse processor, and low-noise high and low voltage power supply; the host computer software mainly includes parameter configuration module, particle event information receiving module, coincidence/anti-coincidence measurement module, and spectrum line display module.
