Dosimetry of Charged Particles Using Lyoluminescence Method
Abstract
Interaction of charged particles – protons, nitrogen, oxygen and carbon ions with LiF single crystals were studiedusing lyoluminescence method. Obtained linear energy transfer profiles were compared with those onescalculated by Monte Carlo method. The shape of the calculated and measured profiles was found to becomparable with Brag’s curve. Analyses of differences in shape of calculated and experimentally measuredcurves were performed. It is demonstrated that by gradually dissolving the crystal in the form of a disk, rotatingit with constant angular rate around its axis of symmetry, it is possible to determinate the defect distribution overthe crystal depth with a resolution of the order of 1μm according to measurements of lyoluminescence intensity.Also, a good precision of lyoluminescence intensity measurement and agreement of experimental energy lossprofiles with the theoretical ones are noted. Significant deviations from calculated profiles were observed indistances closer than 10-6 m to solid surface.
