Kubva payakavandudzwa pakati pezana ramakore rechi20, nzira yekuverenga yemvura scintillation yave musimboti wekutsvagisa muminda yenyukireya fizikisi, biomedical uye sainzi yezvakatipoteredza. Musimboti wemusimboti uri muchokwadi chekuti twumipundu twakaburitswa panguva yekuora kweradionuclides kudyidzana ne scintillation fluid, ichishandura simba kuita mafotoni anooneka. Aya mafotoni anoshandurwa kuita masaini emagetsi nemafotodetectors (semuenzaniso, machubhu ephotomultiplier, PMTs), ayo anozoongororwa kuti averenge huwandu hwezvinhu zvine radioactive.

Kunyangwe iyo aura ye liquid scintillation kuverenga matekiniki anowanzo kutariswa pane detector kana scintillating fluid pachayo, scintillation vials, semidziyo inoisa zvakananga sampuli uye scintillating fluid, chinhu chakakosha chakavanzika chinotaridza kubudirira kana kutadza kwekuyedza.

Dhizaini ye scintillation vials muchidzidzo chazvino ichine matambudziko. Chinangwa chebepa rino ndechekuongorora zvine hungwaru pesvedzero yebasa uye dhizaini ye scintillation vials pakuita kwavo, uye kupa vaongorori hwaro hwedzidziso uye nhungamiro inoshanda mukusarudza nekushandisa scintillation mabhodhoro nekuongorora basa, optimize dhizaini, kusarudza izvo zvinyorwa, uye kuvandudza mashandiro.Panguva imwecheteyo, inotarisira kune ramangwana rekusimudzira maitiro, ichipa rutsigiro rwekuwedzera optimization uye nekuwedzera kwekushandisa kweLSC tekinoroji.

Mhedziso yeLiquid Scintillation Counting Technology

1. Nheyo Yekutanga: Precision Chain yeKushandura Kwesimba

Iyo musimboti weiyo liquid scintillation kuverenga iri mukuita kwese kushandura radioactive kuora simba kuita optical sign kuburikidza ne scintillation fluid, uye maitiro ayo ehunyanzvi anogona kupatsanurwa kuita radiation excitation, photon chizvarwa, optical sign capture, uye data analysis.

2. Kuongororwa kweChikamu Technology Segments

• Kugadzikana kutonga kwe scintillation solution: dzivisa hydrolysis (semuenzaniso ethylene glycol-based scintillation solution inoda kuwedzera antioxidant BHT) kana photolysis (toluene-based solution inoda kuchengetwa kure nechiedza); chikamu che scintillation solution (eg ethylene glycol system ine PPO) iri nyore kutora makristasi pakudzika kwakadzika (＜4 ℃), izvo zvinotungamirira kukudonha kamwe kamwe mukubudirira kwekubuda kwechiedza.
