GAGG:Ce detector:
Sinokubonelela nge-Dia60x180mm GAGG ingot, ngokwesicelo esahlukileyo, ubungakanani obulungiselelweyo buyasebenza.
Intshayelelo
KHD-1 scintillation detector sisizukulwana esitsha γ-ray isixhobo somlinganiselo.Idityaniswe negumbi elikhokelayo kunye ne-Multi-channel Analyzer (MCA) ukwenza i-Energy Spectrometer, esetyenziswa ngokubanzi kwindawo ebuthathaka yohlalutyo lwe-radioactivity, njengezinto zokwakha, ukutya, i-geology njl.
Inzuzo ye-KHD-1 scintillation detector iquka ubume obubambeneyo, ukusebenza ngokulula, imvelaphi ephantsi, isisombululo esigqwesileyo samandla, iziphumo ezizinzileyo, ukuthembeka okuphezulu, ukuqina kunye nokusebenza kakuhle kokuchongwa.
