摘要：

In this paper, the measurements of energy loss and energy loss straggling for 1-10 key monoenergetic positrons passing through thin carbon foils of different thicknesses ranging from 1.0 to 5.0 mu g/cm(2) are presented. The stopping power dE/dx and positron transmission coefficient as a function of incident positron energy and foil thickness have also been investigated. Particularly, the experimental results obtained are compared with those from Monte Carlo simulation and theory with a view to providing a way to determine the actual thickness of a carbon foil. The ratio of the energy straggling to the foil thickness seems to have a linear relation with the beam energy. (C) 2011 Elsevier B.V. All rights reserved.
