Buffered spectrally-peaked proton beams in the relativistic-transparency regime

N. P. Dover, M. J. V. Streeter, C. A. J. Palmer +23

Spectrally-peaked proton beams ($E_p\approx 8$ MeV, $\Delta E\approx 4$ MeV) have been observed from the interaction of an intense laser ($>10^{19}$ Wcm${}^{-2}$) with ultrathin CH foi…
