Waxaan ku siin karnaa qalabka wax baadha ee PMT, SiPM ama PD.Waxa lagu dabaqi karaa ujeeddooyin badan sida spectrometer shucaaca, qiyaasaha shakhsiyeed, sawirka amniga, signalka garaaca wadnaha, signalka dhijitaalka ah, tirinta sawirka iyo cabbirka.
Taxanaha alaabtayadu waa sida soo socota:
1. Baadhiyaha taxanaha SD
2. Baadhiyaha taxanaha aqoonsiga
3. Qalabka raajo ee tamarta hoose
4. Baadhiyaha taxanaha SiPM
5. Baadhiyaha taxanaha PD
Baadhaha Taxanaha SD
Baadhitaannada taxanaha SD waxay ku duubaan crystal iyo PMT hal guri, taas oo ka gudubta faa'iido darrada hygroscopic ee kiristaalo qaarkood oo ay ku jiraan NaI (Tl), LaBr3: Ce, CLYC.Marka baakadaha PMT, walxaha gaashaanka juqraafiyeedka gudaha ayaa hoos u dhigay saameynta goobta geomagnetic ee qalabka wax baaraha.Lagu dabaqi karo tirinta garaaca wadnaha, cabbiraadda spectrum tamarta iyo cabbirka qiyaasta shucaaca.
Baadhaha Taxanaha Aqoonsiga
Kinheng waxay awood u leedahay naqshadaynta isku dhafan.Iyada oo ku saleysan aaladaha taxanaha SD, baareyaasha taxanaha aqoonsiga waxay isku daraan qaybaha elektiroonigga ah, fududeeyaan interface-ka, oo ay fududeeyaan adeegsiga qalabka wax baaraha gamma.Iyada oo ay taageerayaan wareegyada isku-dhafka ah, qalabka aqoonsiga taxanaha aqoonsiga ayaa bixiya isticmaalka tamarta hoose, dhawaaqa calaamadaha hoose, iyo hawlo badan oo awood leh marka la barbardhigo qalabkii hore ee isku midka ah.
Qeexitaan baaraha:
Qalabka wax lagu baadho waa qalab isticmaala scintilators si loo ogaado loona cabbiro noocyada kala duwan ee shucaaca sida alfa, beta, gamma iyo raajada.Scintillators waa walxo iftiimaya marka ay ku faraxsan yihiin shucaaca ionizing.Iftiinka la sii daayo ayaa markaas lagu ogaanayaa iyadoo la isticmaalayo sawir-qaade sida tuubbada sawir-qaadista (PMT), taasoo iftiinka u beddeleysa calaamad koronto oo la cabbiri karo lana falanqeyn karo.
Qalab-sheegaha waxa uu ka kooban yahay kristaan, hagaha nalka ama milicsada, sawirqaade, iyo qalab elektaroonik ah oo la xidhiidha.Marka shucaaca ionizing uu galo kristal scintilator, wuxuu kiciyaa atamka gudaha, taasoo ka dhigaysa inay dhalaalto.Iftiinka ayaa markaa haga ama ka muuqda sawir-qaade, kaas oo iftiinka u beddelaya calaamad koronto oo u dhiganta tamarta shucaaca dhacdada.Qalabka elektaroonigga ah ee isku xidhan ayaa markaa farsameeya calaamada oo bixiya cabbirka qiyaasta shucaaca.
Dareemayaasha Scintillator ayaa si weyn loogu isticmaalaa sawirka caafimaadka, daaweynta shucaaca, fiisigiska nukliyeerka, la socodka deegaanka, iyo codsiyada kale ee u baahan ogaanshaha iyo cabbirka shucaaca ionizing.Dareenkooda sare, xallinta tamarta wanaagsan, iyo waqtiga jawaabta degdegga ah ayaa ka dhigaya kuwo ku habboon codsiyo kala duwan.
