BaF2 Scintillator, BaF2 crystal, BaF2 scintillation crystal

I-BaF2 Scintillator, ikristale ye-BaF2, ikristale ye-BaF2 ye-scintillation yekristale ebonakalayo

inkcazelo emfutshane:

I-BaF2 scintillator ineepropathi ezigqwesileyo ze-scintillation kunye nokuhanjiswa kwe-optical kuluhlu olubanzi lwe-spectrum.Ithathwa njengezona scintillators zikhawulezayo ukuza kuthi ga ngoku.Icandelo elikhawulezayo lingasetyenziselwa ukulinganisa ixesha ngokuchanekileyo kunye nokufumana isisombululo sexesha elifanelekileyo, liye lalandelwa njenge-scintillator ethembisayo kuphando lokutshabalalisa i-positron.Ibonisa ubulukhuni bemitha yemitha ukuya kuthi ga kwi-10⁶rad okanye nangaphezulu.Iikristale ze-BaF2 zineempawu ezigqwesileyo ze-scintillation ngenxa yokukwazi kwabo ukukhupha ngaxeshanye izinto ezikhawulezayo nezicothayo zokukhanya, okwenza umlinganiselo wamandla ngaxeshanye kunye ne-spectra yexesha ngamandla aphezulu kunye nesisombululo sexesha.Ke ngoko, i-BaF2 inoluhlu olubanzi lwezicelo kwiinkalo zefiziksi yamandla aphezulu, ifiziksi yenyukliya kunye namayeza enyukliya.

Ingcaciso yeMveliso

I-BaF2 imele i-barium fluoride.Yikhompawundi eyenziwe nge-barium kunye neeathom ze-fluorine.I-BaF2 yikristale eqinileyo enesakhiwo se-cubic kwaye iyabonakala kwimitha ye-infrared.Ngenxa yeempawu zayo ezilungileyo zothumelo kuluhlu olubanzi lwamaza, lihlala lisetyenziswa njengesixhobo seelensi, iifestile kunye neeprism kwintsimi ye-optics.Ikwasetyenziswa kwi scintillation detectors, thermoluminescent dosimeters, kunye nezinye izicelo ezifuna ukuchongwa ngeradiation.I-BaF2 ineqondo eliphezulu lokunyibilika kwaye ayinyibiliki emanzini, nto leyo eyenza ibe yinto eluncedo kumaqondo obushushu aphezulu kunye neendawo ezidlekayo.

Uvavanyo lokuSebenza

Imbonakalo yamandla e-2 × 2 × 3 mm3 yeekristale ze-BaF2 ezilinganiswe (a) kulungiselelo lwe-HF kunye (b) nokuseta i-ASIC kumbane othambekele ekusetyenzisweni kwama-60 V, kunye nomda we-100-mV kumlinganiselo we-HF kunye ne-6.6 mV Ukusekwa kwe-ASIC.I-spectrum ye-HF yi-spectrum ye-coincidence, ngelixa i-ASIC ibonisa i-spectrum ye-detector enye kuphela.
