NaI(Tl) Scintillator, NaI(Tl) Crystal, NaI(Tl) Scintillation Crystal

inkcazelo emfutshane:

I-NaI(Tl) yeyona nto isetyenziswa kakhulu kwi-scintillation imathiriyeli ngenxa yokungabizi kakhulu.Inemveliso yokukhanya ephezulu, ukusebenza kakuhle kokubona, ubungakanani obukhulu obukhoyo kunye neendleko ezithe kratya xa kuthelekiswa nezinye izinto zescintillation.I-NaI(TI) ine-hygroscopic kwaye kufuneka ifakwe kwi-hermetically kwizindlu (iStainless Steel, i-Titanium Alloy, enye indawo ye-Al yezindlu).

Ubume kunye nobukhulu obuqhelekileyo: Ukuphela-kakuhle, i-cubic Shape, icala livuleke kakuhle, isilinda.Dia1"x1", Dia2" x2, Dia3"x3", Dia5"x5", 2"x4"x16", 4"x4"x16", Anti-Compton detector.

Ifumaneka kwikristale enye, i-polycrystalline okanye iikristale ezibunjiweyo kushishino lokugawulwa kweoyile.

Ingcaciso yeMveliso

I-NaI(Tl) imele i-sodium iodide edityaniswe nethallium.Yimathiriyeli ye-scintillation esetyenziselwa ukubona ukukhanya kwemitha, ngakumbi imitha ye-gamma.Xa imitha ye-gamma ibetha ikristale ye-NaI(Tl), ibangela ukuba ii-athom ze-Tl zikhuphe ilitha lokukhanya, elibhaqwe yi-photocathode kwaye liguqulwe libe ngumqondiso wombane.I-NaI(Tl) iqhele ukusetyenziswa kwi-gamma spectroscopy, umfanekiso wezonyango, kunye nokuhlolwa kokusingqongileyo.

I-polycrystalline scintillator yi-scintillator eyenziwe ngeenkozo ezincinci ze-crystal ezininzi endaweni ye-crystal enkulu efana ne-crystal scintillator enye.La masuntswana amancinane adla ngokukhuliswa kunye ngenkqubo ebizwa ngokuba yi-solid-state sintering, apho amasuntswana ngamanye adityaniswa kunye aze afudunyezwe kumaqondo obushushu aphezulu ade adibane kunye.Oku kwahlukile kwinkqubo yokukhula kwekristale enye esetyenziselwa i-crystal scintillators enye.I-Polycrystalline scintillators ineenzuzo ezininzi ngaphezu kwe-crystal scintillators enye, njengeendleko eziphantsi zemveliso kunye nokuphucula ukuzinza komatshini kunye ne-thermal.Nangona kunjalo, banokuba nesisombululo esisezantsi samandla kunye nokukhutshwa kokukhanya okuphantsi xa kuthelekiswa ne-crystal scintillators enye.
