This work is a study of laser-driven neutron production effected by different internal target structures via the Particle in Cell code KLAPS and a Monte Carlo post-processor. It has been illustrated in the manuscript titled “Effects of internal target structures on laser-driven neutron production” [Zhang et al 2019 Nucl. Fusion https://doi.org/10.1088/1741-4326/ab1cda].
