Thermoluminescence properties of LiMgF3 doped with Ce, Er and Dy. Radiation protection dosimetry, 2002, Volume: 100, Issue:1-4 The main dosimetric properties are reported of a new perovskite, LiMgF3, doped with Ce, Er and Dy impurities. An annealing temperature of 400 degrees C for one hour is necessary to erase any previous signal and to stabilise its sensitivity. A readout up to 450 degrees C gives the same result. The glow curve structure consists of two intense and isolated glow peaks at 170 degrees C and 315 degrees C. The sensitivity of both glow peaks to beta irradiation increases as the dopant concentration increases. The sensitivity is higher than that of LiF:Mg,Ti using the glow peaks 4+5 integral. Other properties like TL dose response, fading, sensitivity versus successive readout and ammealing cycles, sensitivity versus the heating rate, sensitivity to light and trapping parameter evaluation were also carried out.

Guang pu xue yu guang pu fen xi = Guang pu, 2002, Volume: 22, Issue:4 A method of determinating the degree of polarization of grating, polarizer and analyzer at some wavelength is introduced. The degrees of polarization of LiF polarizers were determined with 1 m Seya-Namioka monochromator by this way. The source is hollow cathode source. The degrees of polarization of two, four and eight LiF plates were measured at 120, 149.2, 174.2, 214.2, 235.0, 300 and 340 nm. The theoretical and experimental reults were consistent within the error. The angular extinction dependence of the LiF polarizer and analyzer was measured at VUV wavelengths. The results showed the expected cosine square dependence, so a high degree of polarization was indeed produced. Also, the LiF polarizer was used to measure the polarization characters of the Al + MgF2 reflectance and the absolute grating efficiency at both parallel and perpendicular to their incident plane.
