Cranfield Online Research Data (CORD). Poster. https://doi.org/10.17862/cranfield.rd.10109921.v2https://dspace.lib.cranfield.ac.uk/handle/1826/21446Non-linear Compton scatter (NCS) and bremsstrahlung radiation both contribute to the X-rays produced in laser-solid interactions. While it is expected that NCS will efficiently generate X-rays for next generation lasers, the weaker NCS yields from laser-solid interactions in existing facilities have not yet been observed due to the bremsstrahlung background. This work attempts to derive a quantitative description of the bremsstrahlung efficiency, for interactions between ultrahigh-intensity short-pulse lasers and thin-foil targets. This model was tested against simulations from the particle-in-cell code EPOCH, which has been extended to include bremsstrahlung modelling capabilities. The relative efficiencies of bremsstrahlung and NCS will be compared to seek NCS signatures for experimental observation.CC BY-NC 4.0https://creativecommons.org/licenses/by-nc/4.0/'Bremsstrahlung''Laser''Synchrotron''DSDS19 Poster''DSDS19''Condensed Matter Imaging''Lasers and Quantum Electronics'Poster10.17862/cranfield.rd.10109921.v2
