Abstract

The Monte Carlo Particle and Heavy Ion Transport code (PHITS) was used for diagnosing the focusing and defocusing action of a triplet of permanent magnet quadrupoles on laser-accelerated proton bunches of short duration. The code predicts reasonably well the observed transverse beam profile as measured with a CR-39 track detector demonstrating that PHITS can be used to simulate proton bunch transport by conventional ion optics in the laser-driven case.
