The effect of alpha-particle dose on the dielectric properties of solid state nuclear track detectors

Dielectric constants and dielectric losses of CR-39 diglycol carbonate and Makrofol polycarbonate have been measured in the frequency range from 100 H z to 100 kHz for the solid stale nuclear track detector (SSNTD). The sample s from these detectors were irradiated with alpha-particles of initial ener gies at levels between 5.1 and 34 MeV. The dielectric constant and dielectr ic loss of the unirradiated samples are also measured to increase at heatin g up to 90 degrees C. The frequency dependence of the dielectric constant i s characterized by a primary relaxation process. In addition, the effects o f alpha-particle dose on the frequency dependencies of the dielectric const ant and its loss have been measured at room temperature. The alpha-particle dose gives an advantage for the increasing correlation between the dielect ric constant and the physical degradation which is related to the increase in the degree of soft segments.
