A study of the CR-39 track detector sensitivity to heavy charged particles of space radiation

摘要

The sensitivity of the 1-mm-thick solid-state CR-39 TASTRAK track detector to space radiation particles in a wide linear energy transfer range, alpha particles with energies near the Bragg peak, and accelerated Ar-39 nuclei with different angles of incidence has been measured. Various approaches to track scanning and data processing algorithms were used to measure the sensitivity. Comparative analysis of experimental results is presented. Practical recommendations on the application of obtained results for evaluation of nuclear track detectors exposed in low-Earth orbit were developed.
