　　Intense ion- and laser beams are complimentary tools to induce High Energy Density in matter, and fusion reactions. An overview will be presented of the projects in fusion related High Energy Density science at Xi’An Jiaotong University. Due to recent developments, we will address the proton-11Boron fusion reaction. We are investigating the reaction using conventional accelerator beams and intense laser generated proton beams. Accelerator facilities used were at the Institute of Applied Nuclear Physics (SINAP, Shanghai) and the 320 kV high voltage platform at the Institute of modern Physics in Lanzhou. There are different reaction channels, but in no case three alpha particles are emitted with each 2.7MeV energy. In the experiments at IMP-Lanzhou we also used hydrogen doped boron targets and the alpha yield in this case is increased by approximately 30%. In experiments with intense proton beams at the Laser Fusion Research Center in Mianyang we observed up to 10¹⁰/sr/ alpha particles per laser-shot. This presently constitutes the highest yield normalized to the laser energy on target.

　　报告人简介：

　　Professor Hoffmann graduated in physics from the Ruhr-Universit?t Bochum (Germany) in 1975. He then completed his doctorate at the Technical University of Darmstadt until 1979. This was followed by a stay abroad at Stanford University, California, USA (Alexander-von Humboldt fellowship) and again a position at the TU Darmstadt, which lasted until 1982. Professor Hoffmann then worked for the Max Planck Institute of Quantum Optics in Garching near Munich and for the Gesellschaft für Schwerionenforschung in Darmstadt. He habilitated at the TU Darmstadt in 1993 and accepted a professorship in experimental nuclear physics at the University of?Erlangen. In?1998 he became professor of nuclear physics in Darmstadt. In 2017 he accepted a professorship as especially appointed professor under the 1000 talents program of China.

　　Scientific Work: Professor Hoffmann is author and co-author of more than 400 peer reviewed scientific articles covering the areas of Nuclear Physics, Plasma Physics and Astroparticle Physics. His special interest is in High Energy Density Physics related to Fusion Science.
