Evaluation of dose level in a laser-driven ion accelerator using PHITS code

Abstract

The laser-driven particle accelerator has become attractive in view of recent progress in laser-handling techniques and the development of various target materials. To develop a laser-driven accelerator, it is necessary to establish a benchmark for the difference between the simulated and measured radiation shielding level. The Monte Carlo particle and heavy ion transport code system (PHITS) was used to establish the benchmark dose for a laser-driven cluster-target-type accelerator. The result was in good agreement with the measurement data.
