BaF2 Scintillator, BaF2 crystal, BaF2 scintillation crystal

wehewehe pōkole:

Loaʻa i ka scintillator ʻo BaF2 nā waiwai scintillation maikaʻi loa a me ka lawe ʻana i ka optical ma luna o ka laulā ākea ākea.Manaʻo ʻia ʻo ia ka scintillators wikiwiki loa i kēia manawa.Hiki ke hoʻohana ʻia ka ʻāpana wikiwiki e ana i ka manawa kūpono a loaʻa ka hoʻonā manawa maikaʻi, ua alualu ʻia ʻo ia ma ke ʻano he scintillator hoʻohiki i ka noiʻi ʻana o ka positron annihilation.Hōʻike ia i ka paʻakikī radiation maikaʻi a hiki i ka 10⁶rad a oi aku paha.Loaʻa i nā kristal BaF2 nā waiwai scintillation maikaʻi loa ma muli o ko lākou hiki ke hoʻokuʻu i nā mea māmā wikiwiki a lohi i ka manawa like, hiki ke ana like i ka ikehu a me ka manawa kikoʻī me ka ikaika kiʻekiʻe a me ka hoʻonā manawa.No laila, loaʻa i ka BaF2 ka nui o nā noi ma nā kahua o ka physics ikehu kiʻekiʻe, ka lāʻau nuklea a me ka lāʻau nuklea.

ʻO BaF2 ke kū nei no ka barium fluoride.He hui ia i hui ʻia me ka barium a me nā ʻātoma fluorine.ʻO ka BaF2 kahi paʻa kristal me kahi ʻano cubic a ʻike ʻia i ka radiation infrared.Ma muli o kāna mau waiwai hoʻoili maikaʻi ma luna o kahi ākea ākea ākea, hoʻohana pinepine ʻia ʻo ia ma ke ʻano he mea no nā lens, nā puka makani a me nā prisms i ke kula optics.Hoʻohana ʻia ia i nā mea ʻike scintillation, thermoluminescent dosimeters, a me nā noi ʻē aʻe e koi ana i ka ʻike radiation.He wahi heheʻe kiʻekiʻe ʻo BaF2 a ʻaʻole hiki ke hoʻoheheʻe ʻia i loko o ka wai, e lilo ia i mea pono i ka wela kiʻekiʻe a me nā kaiapuni corrosive.

ʻIke ʻia ka ikehu o nā kristal 2 × 2 × 3 mm3 BaF2 i ana ʻia ma ka (a) hoʻonohonoho HF a me (b) hoʻonohonoho ASIC ma kahi voli uila o 60 V, me ka paepae o 100-mV no ke ana HF a me 6.6 mV no ka Hoʻonohonoho ASIC.ʻO ka HF spectrum he coincidence spectrum, ʻoiai ke hōʻike nei ka ASIC i kahi kikoʻī o hoʻokahi wale nō mea ʻike.
