The energy deposition and transportation of intense heavy ion beams in dense plasmas are the frontier topics in fields like high energy density physics and fusion science and technology. They have great potential of making great breakthough and having new discoveries. It was predicted that complex, nonlinear behavior can emerge due to the strong electro-magnetic fields driven by the intense ion beam in dense plasma. These behaviors are far to be fully understood, and high-precision experimental data are scarce. In this proposal, we will use the three laser beams from XGIII to investigate the beam-driven electro-magnetic fields as well as the nonlinear energy deposition and transportation properties of intense ion beam in dense plasma. The foam samples are heated by the X rays from ns laser-driven hohlraum radiation to create uniform quasi-quiescent dense plasmas. The intense ion beams are generated by ps laser through Target Normal Sheath Acceleration mechanism. The electro-magnetic fields in the plasmas are diagnosed by proton beams generated through fs laser acceleration. Based on the experimental data, we will benchmark the related models and establish the physical pictures during the interaction of intense ion beam with dense plasma. The results will give great support for the ion-driven high energy density physics as well as fast ignition.
