Preliminary Study on the Use of the Track Size Distribution on Electrochemically Etched CR-39 Foils to Infer Neutron Spectra
We are studying the relationship between neutron energy and track size distribution on electrochemically etched CR-39 foils using a two-stage etching procedure. Although the electrochemical etching process alters the track size, we now find that the track diameter is related to the neutron energy even after the second stage (blow-up) is completed. This relationship is complex, being affected by the etching parameters, including oven temperature, etching high voltage, and etching time. Current studies are directed at establishing the effect of each of these parameters on the track size distribution and at determining a optimal etching procedure for neutron spectra evaluation.
