Gamma Spectrometry Systems e nang le HPGe Detector

Selelekela sa Sehlahisoa :

RJ46 Gamma Spectrometry Systems e nang le HPGe Detector haholo-holo e kenyelletsa mofuta o mocha oa "high-purity germanium low-background spectrometer" e ntlafalitsoeng e ikemetseng. The spectrometer e nka mokhoa oa ho bala ketsahalo ea likaroloana, 'me e sebelisa mechine e mengata ea digital ho fumana le ho boloka matla (amplitude) le tlhahisoleseding ea nako ea lets'oao la tlhahiso ea HPGe detector.

 

Sebopeho sa sistimi:

Sistimi ea tekanyo ea RJ46 Gamma Spectrometry Systems e entsoe haholo ka likarolo tse tharo: detector e phahameng ea germanium, processor ea li-channel tse ngata, le kamore e etellang pele. Sehlopha sa detector se kenyelletsa HPGe main detector, digital multi-channel pulse processor, le matla a tlaase a phahameng le a tlaase a matla a motlakase; software ea khomphutha e amohelang haholo e kenyelletsa mojule oa tlhophiso ea parameter, tlhaiso-leseling ea ketsahalo ea karoloana e amohelang mojule, mojule oa tekanyo ea tsietsi / anti-coincidence, le module ea ponts'o ea spectrum.

 

Likaroloana:

① E ts'ehetsa litekanyo tse habeli tsa mabone a matla le mabone a nako

② Lintlha li ka fetisoa ka Ethernet le USB

③ Ka software ea ho lekanya hantle feela

④ Nako e phahameng le tharollo e phahameng ea matla, tšehetso e phahameng ea ho feta

⑤ Sebopeho sa filthara ea dijithale, ho tlosoa ha motheo oa othomathike

⑥ E khona ho fumana tlhaiso-leseling ea likaroloana le tlhaiso-leseling ea matla e fetisoang ke sesebelisoa ebe e e boloka e le polokelo

Matšoao a mantlha a tekheniki:

Mofuputsi:

① Mofuta oa kristale: germanium e hloekileng haholo

② Lethathamo la karabelo ea matla: 40keV ~ 10MeV

③ Bokhoni bo nepahetseng: ≥60%

④ Qeto ea matla: ≤2keV bakeng sa tlhōrō ea 1.332 MeV; ≤1000eV bakeng sa tlhoro ea 122keV

⑤ Peak to Compressor Ratio: ≥68:1

⑥ Peak sebopeho parameters: FW.1M/FWHM≤2.0

Digital Multi-Channel Analyzer:

① Sekhahla se phahameng sa ho sebelisa data: ha se ka tlase ho 100kcps

② Phaello: Beha phetoho e thata le e ntle ho fihlela litlhoko tsa ntlafatso ea ts'ebetso ea spectrum amplification.

③ E tsamaellana le li-preamplifiers tse hlokomelang tefiso, li-preamplifiers tsa hajoale, li-preamplifiers tsa motlakase, li-preamplifiers tsa mofuta oa reset, li-preamplifiers tsa mofuta oa ho itokolla, jj.

④ E ts'ehetsa litekanyo tse habeli tsa mabone a matla le mabone a nako

⑤ E fana ka phepelo e tloaelehileng ea DB9 preamplifier, e tsamaellanang le Slot ea NIM

⑥ Mekhoa e mene ea phetisetso: Raw Pulse View, Shaped View, Line View, le Particle Mode

⑦ Mokhoa oa Particle o ts'ehetsa ho lekanya nako ea ho fihla, matla, nako ea ho phahama, nako ea hoetla le lintlha tse ling tsa liketsahalo tsa ray (e ka tloaeleha ha ho hlokahala)

⑧ E ts'ehetsa tlhahiso ea lets'oao le le leng la detector le likenyelletso tse fihlang ho tse 8 tse ikemetseng

⑨ 16-bit 80MSPS, sampole ea ADC, e ka fana ka tšehetso ea mela e fihlang ho 65535
