The Effect of Cathode Configuration on the Distribution of Nuclear Tracks on CR-39 Plastic Detector Chips During Electrolysis

Previous work by this group has shown that nuclear particles generated during electrolysis can be registered by CR39 plastic detectors placed just below the metal cathode. To better understand this phenomenon, the researchers are investigating the distribution of nuclear tracks in CR39 detectors as a function of cathode configuration. Comparisons are made between disk-shaped, annular, and point-source cathodes. Since alpha particles have a charge of -2, it is possible that the distribution of nuclear tracks could be influenced by the intensity and direction of the electric field between the cathode and the CR39 detector. If there is a cathode configuration that yields a higher track density, then this will facilitate further investigation of this phenomenon.
