Theoretical and experimental study of the CR-39 behavior under electron beam

Abstract This work concerns the action of an electron beam on some physical properties of the poly(diethylene bis(allyl carbonate)) CR39 manufactured in Bristol and Limoges laboratories. The material undergoes structural, physical and chemical modifications induced by the incident electrons energy transfer in the substrate. This is similar to the processes generated by the secondary electrons created during ion beam-polymers interactions. An experimental study of the topographic modifications on the CR39 under electron beam is presented. In parallel, a theoretical study using Monte-Carlo simulations and concerning the 3D energy transfer for one diameter of the spot is developed in order to evaluate the radio induced process.
