Annealing characteristics of heavy ion radiation damage in ssntds and concept of single activation energy

Abstract

The concept of single activation energy of annealing introduced by Modgil and Virk [Nucl. Instr. and Meth. B12 (1985) 212] explains the annealing behaviour of radiation damage due to heavy ion beams in both organic and inorganic SSNTDs. The values of activation energy, E a, for soda-lime glass are found to be identical using three different annealing models. Furthermore, the value of E a is independent of the angle of incidence, the energy and the nature of the ion beam used for irradiation and is solely a detector property. It is interesting to note that track annealing based on length and diameter reductions yields similar values of E a for soda-lime glass. The activation energy for CR-39 is found to be 0.19 eV using different ion beam irradiations.
