Gamma Spectrometry Systems yokhala ndi HPGe Detector

Zoyambitsa Zamalonda :

RJ46 Gamma Spectrometry Systems yokhala ndi HPGe Detector makamaka imaphatikizapo mtundu watsopano wa germanium low-background spectrometer wopangidwa pawokha. Ma spectrometer amatengera njira yowerengera zochitika za tinthu, ndipo amagwiritsa ntchito digito yamitundu yambiri kuti apeze ndikusunga mphamvu (matalikidwe) ndi chidziwitso cha nthawi ya chizindikiro cha HPGe chowunikira.

 

Kapangidwe kadongosolo:

Dongosolo la kuyeza kwa RJ46 Gamma Spectrometry Systems limapangidwa makamaka ndi magawo atatu: chowunikira chapamwamba cha germanium, purosesa yamakina ambiri, ndi chipinda chotsogolera. Gulu la detector limaphatikizapo chojambulira chachikulu cha HPGe, purosesa ya digito ya multi-channel pulse, ndi phokoso laling'ono lapamwamba komanso lamagetsi; Mapulogalamu apakompyuta omwe amakhala nawo amaphatikizanso gawo losinthira magawo, chidziwitso cha zochitika za tinthu tating'onoting'ono, gawo loyezera zochitika mwangozi / zotsutsana ndi zochitika, ndi gawo lowonetsera mzere.

 

Mawonekedwe:

① Imathandizira kuyeza kwapawiri kwa sipekitiramu mphamvu sipekitiramu ndi nthawi sipekitiramu

② Zambiri zitha kusamutsidwa kudzera pa Ethernet ndi USB

③ Ndi pulogalamu yoyeserera yokhazikika

④ Kukhazikika kwanthawi yayitali komanso mphamvu zambiri, kuthandizira kopitilira muyeso

⑤ Kujambula kwa digito, kuchotseratu koyambira

⑥ Kutha kulandira zidziwitso zamagawo ndi zidziwitso zama sipekitiramu zamagetsi zomwe zimaperekedwa ndi chipangizocho ndikusunga ngati nkhokwe

Zizindikiro zazikulu zaumisiri:

Chodziwira:

① Mtundu wa Crystal: germanium yoyera kwambiri

② Kuyankha kwamphamvu: 40keV ~ 10MeV

③ Kuchita bwino kwachibale: ≥60%

④ Kusintha kwa mphamvu: ≤2keV kwa 1.332 MeV pachimake; ≤1000eV kwa 122keV pachimake

⑤ Peak to Compressor Ration: ≥68:1

⑥ Mawonekedwe apamwamba kwambiri: FW.1M/FWHM≤2.0

Digital Multi-Channel Analyzer:

① Kuchulukitsa kwa data: zosachepera 100kcps

② Kupindula: Khazikitsani zosinthika komanso zosinthika bwino kuti mukwaniritse zofunikira pakusintha kwa spectrum amplification

③ Zimagwirizana ndi ma preamplifiers tcheru, preamplifiers panopa, voteji preamplifiers, bwererani mtundu preamplifiers, self-discharge mtundu preamplifiers, etc.

④ Imathandizira kuyeza kwapawiri kwa sipekitiramu mphamvu sipekitiramu ndi nthawi sipekitiramu

⑤ Amapereka magetsi oyambira a DB9, ogwirizana ndi kagawo ka NIM

⑥ Mitundu inayi yotumizira: Raw Pulse View, Mawonekedwe Owoneka, Mawonekedwe a Line, ndi Particle Mode

⑦ Particle mode imathandizira kuyeza nthawi yofika, mphamvu, nthawi yokwera, nthawi ya kugwa ndi zidziwitso zina za zochitika za ray (zosintha mwamakonda)

⑧ Imathandizira kuyika kwa siginecha imodzi yayikulu komanso zolowetsa 8 zodziyimira pawokha

⑨ 16-bit 80MSPS, zitsanzo za ADC, zimatha kupereka chithandizo cha mizere ya 65535

⑩ Nthawi yayitali komanso kukonza mphamvu zambiri, kuthandizira kwambiri

⑪ Programmable mkulu mphamvu ndi kuwonetsera

⑫ Zambiri zitha kusamutsidwa kudzera pa Ethernet ndi USB

⑬ Kujambula kwa digito, kuchotseratu koyambira, kuwongolera kutayika kwa ballistic, kuponderezana kwaphokoso pafupipafupi, kukhathamiritsa kwadzidzidzi, zero zero, kuwongolera nthawi yakufa, kukonzanso kwapachiyambi ndi ntchito ya oscilloscope

⑭ Ndi pulogalamu ya GammaAnt yowunikira komanso kukonza makina, imatha kuzindikira ntchito monga kuzindikira kwa nuclide ndi kuyeza kwachitsanzo.

Chipinda chotsogolera chochepa:

① Chipinda chotsogolera ndi choyambirira chophatikizika

② makulidwe otsogolera ≥10cm

Kusanthula kwa Spectrum ndi pulogalamu yopezera:

① Itha kupeza ma sipekitiramu, kuyika magawo, ndi zina.

② Kutha kulandira zidziwitso zamagawo ndi zidziwitso zama sipekitiramu amagetsi zomwe zimaperekedwa ndi chipangizocho ndikusunga ngati nkhokwe

③ Spectral line data processing ntchito amatha kuzindikira tinthu ndi mphamvu sipekitiramu kusanthula deta, kukonza ndi kuonera, ndi kuthandiza deta kuphatikiza, kuwunika ndi kugawa ntchito.

④ Ndi pulogalamu yoyeserera bwino komanso mawonekedwe a kafukufuku
