I-BaF2 Scintillator, i-BaF2 crystal, i-BaF2 scintillation crystal

incazelo emfushane:

I-BaF2 scintillator inezici ezinhle kakhulu zokucwenga kanye nokudluliswa kwe-optical phezu kobubanzi be-spectrum.Ithathwa njengama-scintillator ashesha kakhulu kuze kube manje.Ingxenye esheshayo ingasetshenziswa ukukala isikhathi ngokunembile futhi uthole isixazululo sesikhathi esihle, ilandelwe njenge-scintillator ethembisayo ocwaningweni lokuqothulwa kwe-positron.Ibonisa ubulukhuni bemisebe obuhle kakhulu obufika ku-10⁶rad noma ngisho nangaphezulu.Amakristalu e-BaF2 anezici ezinhle kakhulu zokucwenga ngenxa yekhono lawo lokukhipha ngesikhathi esisodwa izingxenye zokukhanya okusheshayo nokunensa, okuvumela ukukala ngesikhathi esisodwa kwamandla ne-spectra yesikhathi ngamandla aphezulu kanye nokulungiswa kwesikhathi.Ngakho-ke, i-BaF2 inohlu olubanzi lwezinhlelo zokusebenza emkhakheni we-high energy physics, i-nuclear physics kanye nemithi yenuzi.

Incazelo Yomkhiqizo

I-BaF2 imele i-barium fluoride.Kuyinhlanganisela eyakhiwe ngama-athomu e-barium kanye ne-fluorine.I-BaF2 iyi-crystalline solid enesakhiwo se-cubic futhi ibonakala ngale emisebeni ye-infrared.Ngenxa yezakhiwo zayo ezinhle zokudlulisela phezu kobubanzi obubanzi be-wavelength, ivame ukusetshenziswa njengempahla yamalensi, amafasitela namaprism emkhakheni we-optics.Ibuye isetshenziswe kuzitholi ze-scintillation, ama-dosimeters we-thermoluminescent, nezinye izinhlelo zokusebenza ezidinga ukutholwa kwemisebe.I-BaF2 inezinga eliphezulu lokuncibilika futhi ayincibiliki emanzini, okuyenza ibe into ewusizo lapho izinga lokushisa eliphezulu kanye nezindawo ezigqwalile.

Ukuhlolwa kokusebenza

I-spectra yamandla yamakristalu e-BaF2 angu-2 × 2 × 3 mm3 akalwe (a) ekumisweni kwe-HF kanye (b) nokusetha kwe-ASIC kuvoltheji echema engu-60 V, enomkhawulo ongu-100-mV wesilinganiso se-HF kanye no-6.6 mV Ukusethwa kwe-ASIC.I-spectrum ye-HF iyi-spectrum ye-coincidence, kuyilapho i-ASIC ibonisa i-spectrum yomtshina owodwa kuphela.
