英文摘要	Proton acceleration driven by resonance electrons, which are generated through direct laser acceleration in the near critical dense plasma, is proposed. These energetic electron beam is dense and directional. When interacting with a thin foil target, resonance electrons can transmit the target and drive periodical electrostatic field at the back surface with a much longer scale length than the classical target normal sheath field. Therefore protons are more efficiently accelerated in propagation direction of resonance electrons. For a Gaussian laser pulse with pulse duration of 80fs and peak intensity I0 = 1.38??1018W/cm2, the cutoff energy of the output collimated proton beam is 14 MeV, enhanced by a factor of 4. The scaling law predicts proton beam over 100 MeV energy can be generated in laser intensity of 1020W/cm2.; EI; 0
