Abstract:
Generation and propagation of fast electron bunches from interaction of short, ultra intense laser with cone-sandwich target are investigated by PIC (particle-in-cell) simulation. Results are compared with those in the interaction of the same laser parameters with cone-channel target, cone-wire target and cone target. Fast electrons generated by the interaction of intense laser with cone-sandwich target can be effectively collimated and propagated by the quasi-static strong magnetic field generated by the material surface of different densities. Compared with the other three cone-structured target, the more number and the higher energy of the fast electrons are generated by cone-sandwich target. This can well improve the energy conversion efficiency of the laser to fast electrons and the quality of fast electron bunches, which are favorable for the fast ignition energy deposition.
