CR-39 is an example of a solid state nuclear track detector commonly used in the inertial confinement fusion field. These detectors can detect energetic particles such as alphas, protons, deuterons, and tritons as well as neutrons. Recent experiments using CR-39 detectors in Pd/D co-deposition experiments have shown that energetic particles and neutrons are formed and that the source of particles and neutrons is the cathode. The kinetic energy of these particles can be directly converted into electricity. In order to optimize this process, the energy of the particles needs to be determined. In this communication, the results of experiments utilizing spacers between the CR-39 detector and cathode as well as track modeling will be discussed.
