TNSA and specifically the formation of the sheath field on the rear surface of the target needs to be better understood in order to optimize laser driven ion beams for applications such as medical hadron therapy. An understanding of the electron dynamics that control formation of the sheath field in the target is essential and studying x-ray emission from the interaction region provides valuable information about the electron population. For this purpose, preliminary measurements of the spatial and spectral characteristics of the interaction region generated by the irradiation of ultra-thin foil targets by the 1022W/cm2 J-KAREN-P laser have been made via penumbral imaging of the x-ray source and continuum x-ray spectroscopy., OPTO Symposium on Photon and Beam Science}, title = {Spatial and spectral x-ray characterization of the Target Normal Sheath Acceleration regime}, year = {2019} }
