Abstract

This study presents a charged particle spectrometer with an aluminum range filter attached to a CR-39 detector that does not need a calibration curve of energy versus track diameter. A californium (Cf-252) radioactive source with an activity of 160 Bq was used to irradiate groups 1, 2, and 3 of CR-39 detectors, each of five samples, at alpha energies of 2.7, 3.86, and 5.11 MeV. Different alpha energies were achieved by changing the source–detector distance. Two aluminum range filters of thicknesses 17 and 11 μ m were used in conjunction with CR-39 detectors to separate alpha particles according to their energy. The thickness of the filter was determined by the SRIM 2013 version. The tracks in group 1 (bare CR-39) are for alpha particles with energies of 2.7, 3.86, and 5.11 MeV, while the tracks in group 2 (CR39 + 11 μ m filter) are for alpha particles with energies of 3.86 and 5.11 MeV. Alpha particles with an energy of 2.7 MeV are blocked by the 11- μ m Al filter. The filter in group 3 (17 μ m) blocked alpha particles with energies of 2.7 and 3.86 MeV and allowed the alpha particles of 5.11 MeV to pass and produce tracks. Therefore, the average number of tracks in group 3 is for 5.11 MeV alpha particles. The tracks for alpha particles of energy 3.86 MeV can be found by subtracting the tracks in group 3 from those in group 2. The difference between the average number of tracks in groups 1 and 2 is for alpha particles with an energy of 2.7 MeV. The present method could determine the tracks from each different alpha energy without using the calibration curve of energy versus track diameter.
