Abstract

The thermally stimulated luminescence (TSL) and exoemission (TSE) in Li and Cu doped NaF and LiF single crystals irradiated with electron high energy electron beams of (10 MeV, doses 0.75 and 2 MGy) have been investigated. The results obtained reveal important properties that suggest that the crystals have a sufficient radiation stability and sensitivity for high energy electron beams and are promising for application as high-dose detectors of electron radiation.

Highlights

  • Considerable progress has been made over the last decades in the development and characterization of many kinds of thermoluminescence (TL) phosphors among which alkali fluorides have always been of notable importance [1,2,3,4]

  • Commercial thermoluminescence dosimeters (TLDs) based on LiF:Mg,Ti (TLD100/600/700) and LiF:Mg,Cu,P (TLD-100H/600H/700H) and their modifications are well accepted in the industry

  • It was recently shown that LiF based TLD may be prospective for application in extremely wide dose range of up to twelve orders of magnitude. This inspired us to test thermally stimulated processes of NaF and LiF doped with Li and Cu irradiated with ultra-high dose of electron beam. To this end we performed an experimental study of TL and thermally stimulated exoemission (TSEE) glow curves of LiF and NaF doped with Li and Cu irradiated with ultra-high doses of 10 MeV electron beams
