Abstract: A prototype of a laser driven proton accelerator is built at Peking University.Protons exceeding 10MeV are accelerated from micrometer-thick ahuminum targets irradiated by tightly focused laser pulse with 1.8J energy and 30fs duration.The beam energy spectrum and charge distribution are measured by a Thomson parabola spectrometer and radiochromic film stacks.The sensitivity of proton cut-off energy to the focusing of the laser beam,the pulse duration,and the foil thickness are systematically investigated in the experiments.Stable proton beams have been produced with an optimized parameter set,providing a cornerstone for the future applications of laser accelerated protons.
