The temperature dependence of optically stimulated luminescence from α-Al2O3:C
B.G. Markey,Stephen W.S. McKeever,Mark S. Akselrod,Lars Bøtter-Jensen,N. Angersnap Larsen,L.E. Colyott +5 more
TL;DR: In this article, the results of experimental measurements and computer simulations on optically stimulated luminescence (OSL) from α-Al 2 O 3 :C are described and the intensity of the OSL observed during illumination of irradiated specimens with visible light is temperature dependent.
Journal ArticleDOI
Ionisation density dependence of the optically and thermally stimulated luminescence from Al2O3:C.
TL;DR: An overview of recent results on ionisation density dependence of the thermally stimulated luminecence (TL) and optically stimulated luminescence (OSL) signals from Al2O3:C is presented, with emphasis on the sensitivity, efficiency, shape of the TL/OSL curves and the emission spectrum.
Journal ArticleDOI
A fiber-dosimetry method based on OSL from Al2O3: C for radiotherapy applications
R. Gaza,Stephen W.S. McKeever,Mark S. Akselrod,Anna E. Akselrod,T. Underwood,C. Yoder,Claus E. Andersen,Marianne C. Aznar,C. J. Marckmann,Lars Bøtter-Jensen +9 more
TL;DR: Two modes of operation of the high-sensitivity, fiber-optic dosimetry system based on optically stimulated luminescence (OSL) and radioluminescence from Al 2 O 3 :C single-crystal fibers (detectors) are described and algorithms that provide accurate estimation of dose rate and integrated dose in near real time are discussed.
Journal ArticleDOI
The natural thermoluminescence of meteorites: II. Meteorite orbits and orbital evolution
TL;DR: In this paper, the authors used thermoluminescence (TL) data for 26 meteorites to calculate the equilibrium natural TL level in ordinary chondrites that are indicative of TL's usefulness as an indicator of perihelion.
Journal ArticleDOI
Relative optically stimulated luminescence and thermoluminescence efficiencies of Al2O3:C dosimeters to heavy charged particles with energies relevant to space and radiotherapy dosimetry
Gabriel O. Sawakuchi,Eduardo G. Yukihara,Stephen W.S. McKeever,Eric Benton,R. Gaza,Yukio Uchihori,Nakahiro Yasuda,H. Kitamura,H. Kitamura +8 more
TL;DR: In this paper, a comprehensive characterization of the thermoluminescence and optically stimulated luminescence (OSL) relative luminecence efficiencies of carbon-doped aluminum (Al2O3:C) for heavy charged particles (HCPs) with atomic numbers ranging from 1 (proton) to 54 (xenon) and energies ranging from 7 to 1000 MeV/u, was presented.
