The attached zip contains both data and analysis scripts for the first two particle-in-cell examples in the associated paper. In particular,

(1) The BeamExpansion folder contains output z vs r phase space data from the quasi-Helmholtz FEMPIC code used in the paper at 3 ns (fempic.csv), as well as the equivalent data from an XOOPIC simulation (xoopic.txt).
