The changes in the absorption spectra induced by Co60 irradiation and high temperature annealing was studied for selected PbWO4 crystals. Based on radiation annealings spectra, four color centers are proposed, which could be responsible shaping spectrum of crystals below 3.6 eV, namely Pb3+, O−, F, F+ centers. Thermoluminescence (TSL) glow curves above room were also these samples to determine further trap levels resulting from irradiation. Correlation between results obtained TSL is discussed.

We report the properties of precision time structures cosmic nuclei He, Li, Be, B, C, N, and O fluxes over an 11-year solar cycle from May 2011 to November 2022 in rigidity range 1.92 60.3 GV. The show similar but not identical variations with amplitudes decreasing increasing rigidity. In particular, below 3.64 GV B fluxes, 2.15 are significantly less affected by modulation than He flux. observe that these differences linearly correlated spectral indices fluxes. This shows, a...
Correlated measurements of emission spectra, photoluminescence and scintillation decays, thermoluminescence, light yield were performed on a selected set undoped La-doped PbWO4 single crystals. The samples grown from 5N purity raw powders show the blue component only. Distinct influence La doping was found in thermoluminescence characteristics. It is discussed direct suppressing creation point defect centers lattice, which are involved energy transfer storage processes this material.
The Alpha Magnetic Spectrometer (AMS-02) is an experiment which will be mounted on the international space station (ISS) to measure primary cosmic ray spectra in space. A key element transition radiation detector (TRD) extract e/sup +/ or p/sup -/ signal reducing background by a rejection factor 10/sup 2/--10/sup 3/ energy range from 10 300 GeV. This used combination with electromagnetic calorimeter provide overall of 6/ at 90% efficiency. consists 20 layers 6 mm diameter straw tubes...
