BaF2 Scintillator, BaF2 kristu, BaF2 ya kirisiti

BaF2 Scintillator, BaF2 kristal, BaF2 scintillation kristu Yerekanwe

ibisobanuro bigufi:

BaF2 scintillator ifite ibintu byiza bya scintillation hamwe nogukwirakwiza optique kumurongo mugari.Bifatwa nkibisumizi byihuta kugeza ubu.Ikintu cyihuta gishobora gukoreshwa mugupima igihe neza no kubona igihe cyiza cyo gukemura, cyakurikiranwe nka scintillator itanga icyizere mubushakashatsi bwo kurimbura positron.Irerekana ubukana bwimirasire igera kuri 10⁶rad cyangwa nibindi byinshi.Ikirangantego cya BaF2 gifite ibintu byiza cyane bya scintillation bitewe nubushobozi bwabo bwo gusohora icyarimwe ibice byihuse kandi bitinda, bigafasha icyarimwe gupima ingufu nigihe cyerekanwa hamwe ningufu nyinshi hamwe nigihe cyo gukemura.Kubwibyo, BaF2 ifite uburyo bwinshi bwo gukoresha mubijyanye na fiziki yingufu nyinshi, fiziki ya kirimbuzi nubuvuzi bwa kirimbuzi.

Ibisobanuro ku bicuruzwa

BaF2 bisobanura fluoride ya barium.Nibintu bigizwe na atome ya barium na fluor.BaF2 ni kristalline ikomeye ifite imiterere ya cubic kandi ikorera mu mucyo.Bitewe nuburyo bwiza bwogukwirakwiza hejuru yumurambararo mugari, ikoreshwa nkibikoresho bya lens, windows na prism mubijyanye na optique.Irakoreshwa kandi muri disikete ya scintillation, dosimeter ya thermoluminescent, nibindi bikorwa bisaba kumenya imirasire.BaF2 ifite aho ishonga cyane kandi ntishobora gushonga mumazi, bigatuma iba ibikoresho byingirakamaro mubushyuhe bwinshi hamwe nibidukikije byangirika.

Kwipimisha Imikorere

Ingufu zerekana ingufu za 2 × 2 × 3 mm3 za kirisiti ya BaF2 yapimwe kuri (a) HF na (b) Gushiraho ASIC kuri voltage ya bias ya 60 V, hamwe na 100-mV yo gupima HF na 6.6 mV kuri Gushiraho ASIC.Ikirangantego cya HF ni ibintu byahuriranye, mugihe ASIC yerekana urutonde rwikintu kimwe gusa.
