Proton beam dosimetry by CR-39 track-etched detector
Background: High and intermediate energy protons are not able to form a track in a solid state nuclear track detector (SSNTD) directly. However, such tracks can be formed through secondary particles created during primary radiation nuclear reactions in a SSNTD. Materials and Methods: The protons with primary energies of 9.6 and 30 MeV available at the cyclotron accelerator with corresponding lo...
متن کاملA parameterization of nuclear track profiles in CR-39 detector
In this work, the empirical parameterization describing the alpha particles’ track depth in CR-39 detectors is extended to describe longitudinal track profiles against etching time for protons and alpha particles. MATLAB based software is developed for this purpose. The software calculates and plots the depth, diameter, range, residual range, saturation time, and etch rate versus etching time. ...
متن کاملEffect of thermal annealing on optical properties of CR-39 polymeric track detector
The samples of CR-39 polymer (TASTRAK, Bristol, England) were annealled thermally at various temperatures ranging from 100oC to 180oC for 1 hour, in air. FTIR spectroscopy reveals the structural degradation of CR-39 polymer due to thermal annealing above its glass transition temperature. Optical band gap of pristine and thermally annealed samples has been determined using UV-Visible absorption ...

متن کاملEffect of Annealing on Track Density in Unirradiated and Gamma Irradiated Cr-39 When Used for Fast Neutron Detection*
The effect of annealing on track density in unirradiated CR-39 and gamma irradiated CR-39 neutron detectors was investigated. One group of CR-39 detectors (25.4 x 12.7 x 0.635 mm) was irradiated with 1.3 kGy of 6oCo gamma rays. The other group of detectors was not irradiated with gamma radiation. The two sets of detectors were then annealed at temperatures ranging from room temperature (2OOC) t...
