Title Spectral modification of laser-accelerated proton beams by self-generated magnetic fields
Contributors
Abstract Target normal measurements of proton energy spectra from ultra-thin (50–200?nm) planar foil targets irradiated by 1019?W?cm?2 40?fs laser pulses exhibit broad maxima that are not present in the energy spectra from micron thickness targets (6??m). The proton flux in the peak is considerably greater than the proton flux observed in the same energy range in thicker targets. Numerical modelling of the experiment indicates that this spectral modification in thin targets is caused by magnetic fields that grow at the rear of the target during the laser–target interaction.
