摘要：
Relative light yield (LY) dependence on temperature for Yb:YAG crystals containing 10% to 100% of Yb dopant is studied for 7 and a excitation. The maximum LY is achieved at 120 K < T< 140 K. LY=(13.5 +/- 2.5) x 10(3) Ph/MeV at T= 140K for (Yb 25%) YAG. Linearity of the light output is checked. alpha/gamma ratio is found to be 0.42 +/- 0.02. Pulse shapes induced by 7 and a particles and cosmic rays are investigated by analysing a set of single events recorded. 7 events are fast (iota < 4 ns), while other kinds of radiation give rise to more complicated and longer profiles, allowing particle discrimination. Dependence of scintillation properties on concentration of Yb and purity is discussed. (C) 2002 Elsevier Science B.V. All rights reserved.
