摘要
In 2014, the study on laser ion sources at IMP was mainly focused on the carbon ion production with a doublepulselaser irradiation scheme, simulations of Direct Plasma Injection Scheme (DPIS), and PoP experiments onlaser ion beam acceleration in a Hybrid Single Chamber (HSC) Linac with DPIS.An optical method was developed to realize thedouble-pulse laser irradiation scheme, with which onecan irradiate a target with two successive laser pulsesusing only one laser. As shown in Fig. 1, the laser beamoutput by a 3 J/ 8 ns Nd:YAG laser is split into twobeams by a beam splitter, then the two laser beamspassing through different optical paths are combined byanother splitter and transported by the same optical system.
