BaF2 Scintillator, BaF2 crystal, BaF2 scintillation crystal

Kufotokozera mwachidule:

BaF2 scintillator ili ndi ma scintillation abwino kwambiri komanso kufalikira kwa kuwala pamitundu yosiyanasiyana.Amatengedwa ngati ma scintillator othamanga kwambiri mpaka pano.Chigawo chofulumira chikhoza kugwiritsidwa ntchito kuyeza nthawi molondola ndi kupeza nthawi yabwino yothetsera, yakhala ikutsatiridwa ngati scintillator yodalirika mu kafukufuku wa positron annihilation.Imawonetsa kuuma kwa ma radiation mpaka 106rad kapena zambiri.Makhiristo a BaF2 ali ndi zinthu zabwino kwambiri zopangira scintillation chifukwa amatha kutulutsa nthawi imodzi mwachangu komanso pang'onopang'ono zowunikira, zomwe zimathandiza kuyeza munthawi yomweyo mphamvu ndi mawonekedwe a nthawi ndi mphamvu yayikulu komanso kusanja nthawi.Chifukwa chake, BaF2 ili ndi ntchito zambiri pazambiri zamphamvu zamagetsi, sayansi ya nyukiliya ndi mankhwala a nyukiliya.

Ubwino

● Imodzi mwa ma scintillator othamanga kwambiri

● Kutulutsa mpweya wotuluka m'maso monga 'kuthamanga' ndi 'kuchedwa'

● Kuwala bwino komanso kuwala

● Zinthu zabwino za Rad-Hard

● Musawole ndi UV

Kugwiritsa ntchito

● Positron Emission Tomography (PET)

● Fiziki yamphamvu kwambiri

● Nuclear physics

● Zida zamankhwala za nyukiliya

● Optical UV-IR zenera

Mafotokozedwe Akatundu

BaF2 imayimira barium fluoride.Ndi gulu lopangidwa ndi maatomu a barium ndi fluorine.BaF2 ndi yolimba ya crystalline yokhala ndi mawonekedwe a cubic ndipo imawonekera ku radiation ya infrared.Chifukwa cha mawonekedwe ake abwino opatsirana pamtunda wautali wautali, amagwiritsidwa ntchito ngati zida zamagalasi, mazenera ndi ma prisms m'munda wa optics.Amagwiritsidwanso ntchito pa scintillation detectors, thermoluminescent dosimeters, ndi ntchito zina zomwe zimafuna kuzindikiridwa ndi ma radiation.BaF2 ili ndi malo osungunuka kwambiri ndipo imasungunuka m'madzi, zomwe zimapangitsa kuti ikhale yothandiza pa kutentha kwakukulu ndi malo owononga.

Kuyesa Magwiridwe

Mphamvu yamagetsi ya 2 × 2 × 3 mm3 BaF2 makhiristo amayezedwa pa (a) HF khwekhwe ndi (b) ASIC kukhazikitsa pa voteji bias 60 V, ndi mozungulira 100-mV muyeso HF ndi 6.6 mV kwa Kupanga kwa ASIC.Mawonekedwe a HF ndi mawonekedwe angozi, pomwe ASIC imawonetsa mawonekedwe a chowunikira chimodzi chokha.
