A umtshina we-scintillationiyithuluzi elisetshenziselwa ukubona nokulinganisa imisebe ye-ionizing njengemisebe ye-gamma nama-X ray.
Umgomo wokusebenza we-aumtshina we-scintillationingafingqwa kanje:
1. Impahla ye-Scintillation: Umtshina wakhiwe ngamakristalu e-scintillation noma i-liquid scintillator.Lezi zinto zinempahla yokukhanya lapho zijatshuliswa imisebe ye-ionizing.
2. Imisebe yesigameko: Lapho imisebe ye-ionizing ihlangana nento yokwenza i-scintillation, idlulisela amanye amandla ayo kumagobolondo e-electron ama-athomu kumpahla.
3. Ukudlidliza kanye nokususa isasasa: Amandla adluliselwa kugobolondo le-electron abangela ama-athomu noma ama-molecule ezinto ze-scintillation ukuthi ajabule.Ama-athomu noma ama-molecule ajabulile abe esebuyela ngokushesha esimeni sawo, akhiphe amandla engeziwe ngendlela yama-photons.
4. Isizukulwane sokukhanya: Ama-photon akhululiwe akhishwa kuzo zonke izinhlangothi, okwenza ukukhanya kokukhanya ngaphakathi kwe-scintillation material.
5. Ukutholwa kokukhanya: Amafotoni akhishiwe abe esetholwa yisithwebuli sezithombe, njengeshubhu le-photomultiplier (PMT) noma ishubhu le-silicon photomultiplier (SiPM).Lawa madivaysi aguqula ama-photon angenayo abe amasignali kagesi.
6. Ukukhulisa isignali: Isignali kagesi ekhiqizwe i-photodetector ikhuliswa ukuze ikhulise ukuqina kwayo.
7. Ukucubungula nokuhlaziywa kwesignali: Isignali kagesi ekhulisiwe icutshungulwa futhi ihlaziywe ngamasekethe kagesi.Lokhu kungase kuhlanganise ukuguqula amasignali e-analog abe amasignali edijithali, ukubala inani lama-photon atholiwe, ukulinganisa amandla awo kanye nokurekhoda idatha.
Ngokukala ukushuba nobude besikhathi sokukhanya okukhiqizwa ngu-aumtshina we-scintillation, izici zemisebe yesigameko, njengamandla ayo, ukuqina, nesikhathi sokufika, zinganqunywa.Lolu lwazi lungasetshenziselwa izinhlelo zokusebenza ezihlukahlukene ekufanekisweni kwezokwelapha, izitshalo zamandla enuzi, ukuqapha indawo ezungezile, nokuningi.
