“…The physical properties of the nuclear track detector CR-39 will be evaluated with PDS. When traversing a plastic material such as CR-39, charged particles create along their ionization track a region that is more sensitive to chemical etching than the rest of the bulk [2]. CR-39 is convenient for the detection of alpha particles and fast neutrons because of high detection efficiency, high sensitivity, and short etching time [3].…”

A novel technique is presented for the assessment of the track response of the detector CR-39 to alpha particles by photothermal deflection spectroscopy and image analysis. The 2 new techniques can be implemented to CR-39 as in situ measurements. The proposed techniques offer the possibility of monitoring nuclear radiation directly. Photothermal deflection is described to detect the change in the thermal and optical properties of the track nuclear detector CR-39 when irradiated to alpha particles. In situ image analysis of the photothermal deflection spot is presented to assess the detection of the CR-39 of any nuclear particle or radiation instantaneously.

“…In 1978, Cartwright et al [1] were the first to demonstrate that Columbia Resin 39 (CR-39), an optically clear, amorphous, thermoset plastic, could be used to detect nuclear particles. When an energetic, charged particle traverses through a solid state nuclear track detector (SSNTD) such as CR-39, it creates along its path an ionization trail that is more sensitive to chemical etching than the bulk material [1,2]. After treatment with a chemical etchant, tracks due to the energetic particles remain in the form of holes or pits which can be examined with the aid of an optical microscope.…”

Solid state nuclear track detectors (SSNTDs), such as CR-39, have been used to detect energetic charged particles and neutrons. Of the neutron and charged particle interactions that can occur in CR-39, the one that is the most easily identifiable is the carbon breakup reaction. The observation of a triple track, which appears as three alpha particle tracks breaking away from a center point, is diagnostic of the 12 C(n, n)3α carbon breakup reaction. Such triple tracks have been observed in CR-39 detectors that have been used in Pd/D co-deposition experiments. In this communication, triple tracks in CR-39 detectors observed in Pd/D co-deposition experiments are compared with those generated upon exposure to a DT neutron source. It was found that both sets of tracks were indistinguishable. Both symmetric and asymmetric tracks were observed. Using linear energy transfer (LET) curves and track modeling, the energy of the neutron that created the triple track can be estimated.
