Deconvolution study on the glow curve structure of LiF:Mg,Ti and LiF:Mg,Cu,P thermoluminescent detectors exposed to 1H, 4He and 12C ion beams

In the case of LiF:Mg,Ti detectors, the low temperature peaks and the main peak are characterized by a general efficiency decrease with the increase of the LET of the incident particle. No remarkable differences were found between detectors enriched with 6Li or 7Li. On the other hand, differences in the structure of the high temperature peaks between the two lithium isotopic compositions were found and discussed. Regarding LiF:Mg,Cu,P detectors, each peak shows a general monotonously decreasing relative efficiency with the increase of LET. In this case, a similar LET dependence was found between 6Li and 7Li based detectors. Furthermore, unusual efficiencies greater than 1 for the low temperature peaks of LiF:Mg,Cu,P exposed to low LET particle were observed.
