I-Gamma Spectrometry Systems ene-HPGe Detector

Isingeniso Somkhiqizo :

I-RJ46 Gamma Spectrometry Systems ene-HPGe Detector ikakhulukazi ihlanganisa uhlobo olusha lwe-high-purity germanium low-background spectrometer ethuthukiswe ngokuzimele. I-spectrometer isebenzisa indlela yokufunda yomcimbi wezinhlayiyana, futhi isebenzisa ishaneli eminingi yedijithali ukuze ithole futhi igcine amandla (i-amplitude) kanye nolwazi lwesikhathi lwesiginali yokuphumayo komtshina we-HPGe.

 

Ukwakhiwa kwesistimu:

Isistimu yokulinganisa ye-RJ46 Gamma Spectrometry Systems ikakhulukazi yakhiwe izingxenye ezintathu: umtshina we-germanium we-high-purity, iphrosesa yesiginali eneziteshi eziningi, negumbi lomthofu. I-detector array ihlanganisa umtshina omkhulu we-HPGe, i-digital multi-channel pulse processor, kanye nomsindo ophansi amandla kagesi aphezulu naphansi; isofthiwe yekhompiyutha ephethe ngokuyinhloko ihlanganisa imojula yokumisa ipharamitha, imojula yokwaziswa komcimbi wezinhlayiyana, imojula yokulinganisa ukuhlangana kwengozi/ukungqubuzana, kanye nemojula yokubonisa i-spectrum line.
