Charge resolution of CR-39 plastic nuclear track detectors for intermediate energy heavy ions

• The charge resolution (delta Z) for heavy ions (nuclear charge: Z = 60 mu m (30 h etching), saturation occurs and there is no further improvement in delta Z. Analysis of the correlations between projectile Z, energy, detector response, and fluctuation of the response make it possible to develop a model to predict the delta Z for projectiles of given Z and energy. The predicted and measured values of delta Z show good agreement within 10%. We conclude that 4
