Calculation of BAS-TR imaging plate responses to carbon and titanium ion beams

Abstract

We calculate BAS-TR imaging plate (IP) responses to laser-accelerated heavy ion beams such as carbon ion beam and titanium ion beam. We introduce two theoretical models widely used for the prediction of an IP response. We perform Monte Carlo simulations based on these two models, and compare the predictions with the available experimental data. Our calculations of the IP response to carbon ions show discrepancy in the location of the maximum IP response, while those to titanium ions present a different slope in the IP response curve. We find that both the linear and the exponential models are insufficient to explain the measured IP responses to carbon and titanium ion beams, and attempt to explain the reason for these differences.
