Scintillation Detector e Etsa'ng?Scintillation Detector Molao-motheo oa Mosebetsi

A scintillation detectorke sesebelisoa se sebelisetsoang ho lemoha le ho metha mahlaseli a ionizing joalo ka mahlaseli a gamma le X-ray.

Molao-motheo oa ts'ebetso ea ascintillation detectore ka akaretsoa ka tsela e latelang:

1. Sesebediswa sa scintillation: detector e entsoe ka scintillation crystals kapa liquid scintillator.Lisebelisoa tsena li na le thepa ea ho ntša leseli ha li thabisoa ke mahlaseli a ionizing.

2. Mahlaseli a ketsahalo: Ha mahlaseli a ionizing a kopana le thepa ea scintillation, e fetisetsa matla a eona ho likhetla tsa elektronike tsa liathomo tse teng.

3. Ho hlasimolla le ho hlasimolla: Matla a fetisetsoang ho khetla ea elektrone a etsa hore liathomo kapa limolek'hule tse linthong tsa scintillation li hlasimolohe.Liathomo kapa limolek'hule tse thabileng li khutlela sebakeng sa tsona ka potlako, li ntša matla a feteletseng ka mokhoa oa photon.

4. Moloko oa leseli: Li-photon tse lokollotsoeng li hlahisoa ka mahlakoreng 'ohle, li hlahisa mahlaseli a leseli ka har'a lisebelisoa tsa scintillation.

5. Ho lemoha khanya: Joale li-photon tse hlahisoang li bonoa ke mochine oa lifoto, tse kang photomultiplier tube (PMT) kapa silicon photomultiplier tube (SiPM).Lisebelisoa tsena li fetolela li-photon tse kenang ho ba matšoao a motlakase.

6. Matlafatso ea lipontšo: Letšoao la motlakase le hlahisoang ke photodetector le matlafatsoa ho eketsa matla a lona.

7. Ts'ebetso ea lipontšo le tlhahlobo: Letšoao le matlafalitsoeng la motlakase le sebetsoa le ho hlahlojoa ke lipotoloho tsa elektronike.Sena se ka kenyelletsa ho fetolela matshwao a analoge ho matshwao a dijithale, ho bala palo ya difoto tse fumanweng, ho lekanya matla a tsona le ho rekota data.

Ka ho metha matla le nako ea ho benya e hlahisoang ke ascintillation detector, litšobotsi tsa mahlaseli a ketsahalo, joalo ka matla, matla le nako ea ho fihla li ka khethoa.Tlhahisoleseding ena e ka sebediswa bakeng sa mefuta e fapaneng ya ditshebediso litšoantšong tsa bongaka, limela tsa matla a nyutlelie, tlhokomelo ea tikoloho, le tse ling.
