Dataset for "Narrow-band acceleration of gold ions to GeV energies from ultra-thin foils"

Dataset underpinning the results presented in the article titled, "Narrow-band acceleration of gold ions to GeV energies from ultra-thin foils", Pulished in Communication Physics (2023) Abstract of the paper: Interaction of intense lasers with nm thick targets provides an attractive regime for the acceleration of ions of all types. Acceleration of heavy ions however is undermined in the presence of low charge contaminant species due to their higher charge-to-mass ratio. Here we show a narrow-band acceleration of very heavy Au ions from ∼15 nm Au foils driven by a sub-Petawatt laser, with spectral peaks of 1.5 ± 0.5 GeV at fluxes on the order of 10^12 particles per steradian. 3D and 2D particle- in-cell simulations show a complex interplay between different acceleration mechanisms at different stages of interaction, suggesting the spectrally peaked Au ion bunches stem from strong radiation pressure acceleration on a heavy-ion dominant plasma in the moments just before transparency, followed by an efficient acceleration due to transparency-enhanced mechanisms.
