Umugenzuzi wa Scintillation akora iki?Ihame ry'akazi rya Scintillation

A icyuma gipimani igikoresho gikoreshwa mugushakisha no gupima imirasire ya ionizing nka imirasire ya gamma na X-ray.

Ihame ry'akazi rya aicyuma gipimairashobora kuvunagurwa muburyo bukurikira:

1. Ibikoresho bya Scintillation: Deteter igizwe na kristu ya scintillation cyangwa scintillator.Ibi bikoresho bifite umutungo wo gusohora urumuri iyo ushimishijwe nimirasire ya ionizing.

2. Imirasire yibyabaye: Iyo imirasire ya ionizing ikorana nibikoresho bya scintillation, yohereza imbaraga zayo mumashanyarazi ya elegitoronike ya atome mubikoresho.

3. Ibyishimo no de-kwishima: Ingufu zihererekanwa mugikonoshwa cya electron zitera atome cyangwa molekile mubikoresho bya scintillation gushimishwa.Atome cyangwa molekile zishimye noneho zisubira vuba mubutaka bwazo, zirekura ingufu zirenze muburyo bwa fotone.

4. Igisekuru cyumucyo: Fotone yasohotse isohoka mubyerekezo byose, ikora urumuri rwumucyo mubikoresho bya scintillation.

5. Kumenyekanisha urumuri: Fotone yasohotse noneho igaragazwa na Photodetector, nka tube Photomultiplier tube (PMT) cyangwa umuyoboro wa silicon Photomultiplier tube (SiPM).Ibi bikoresho bihindura fotone yinjira mubimenyetso byamashanyarazi.

6. Kwiyongera kw'ibimenyetso: Ikimenyetso cy'amashanyarazi cyakozwe na fotodetector cyongerewe imbaraga kugirango cyongere ubukana bwacyo.

7. Gutunganya ibimenyetso no gusesengura: Ikimenyetso cyamashanyarazi cyongerewe imbaraga gitunganywa kandi kigasesengurwa numuzunguruko wa elegitoroniki.Ibi birashobora kuba bikubiyemo guhindura ibimenyetso bisa nibimenyetso bya digitale, kubara umubare wa fotone yagaragaye, gupima imbaraga zabo no gufata amakuru.

Mugupima ubukana nigihe cya flash yakozwe na aicyuma gipima, ibiranga imirasire yibyabaye, nkimbaraga zayo, ubukana, nigihe cyo kuhagera, birashobora kugenwa.Aya makuru arashobora gukoreshwa mubikorwa bitandukanye mumashusho yubuvuzi, amashanyarazi ya kirimbuzi, gukurikirana ibidukikije, nibindi byinshi.
