The protons in the front low-density hydrogen target layer accelerated by the space-charge field of the laser-driven hot electrons can penetrate through the high-Z high-mass and high-density ion layer, resulting in an energetic proton bunch. A part of the latter is further accelerated by the space-charge field of the hot electrons in the vacuum behind the high-Z ion layer. With this scheme, quasimonoenergetic proton bunches can be produced using presently available laser pulses of moderate contrast and durationengArticle is made available in accordance with the publisher's policy and may be subject to US copyright law.
