TL;DR: In this paper, a 1.9 MeV beam line composed of permanent quadrupole magnets (PMQs), a radio frequency (rf) phase rotation cavity, and a tunable monochromator is developed to evaluate and to test the simulation of laser-accelerated proton beam transport through an integrated system for the first time.

TL;DR: The authors obtain a new equation to estimate the forward component of a photon dose generated through the interaction between a target and a short pulse high power laser that can reproduce experimental results obtained and the dose result calculated at other laboratories.
