The effect of infrared laser on the activation energy of CR-39 polymeric detector

These results show that EB for post-exposed and pre-exposed samples remain, to within the experimental uncertainty, comparable to that of un-exposed sample which indicates that laser irradiation has a small effect on EB. Also, the results of ET for post-exposed and un-exposed samples are in close proximity with a slight increase for the former. The increase in ET of pre-exposed CR-39 polymer due to IR exposure is discussed on the basis of cross linking processes occurring during the exposure. This increase in ET leads to the hardening of the detector material of the pre-exposed sample. The hardening of the detector material is crucial in applications of CR-39 polymer such as in cosmic ray and cold fusion research.
