Advanced diagnostics and applications of pulsed ion beams and lasers

Several kinds of experiments are shown concerning the generation diagnostics and applications of pulsed ion beams and lasers. The authors are interested in a few research fields of ICF, material and space sciences. Several high voltage machines both at Yokohama and Albuquerque were used to produce ion beams and laser lights. Proton beams of a few hundred kV energy were produced with a conventional magnetically insulated diode. A cryogenic anode with N2O ice as the candidate ion source was operated with the same kind of high voltage apparatus, and the beam species and divergence were measured with the Baryotrak. The purpose of this experiment was to check the possibility o medium mass ion beams as the ICF energy driver in the near future. Various species of ion beams were focused on to a few kinds of targets, and the ablation processes were observed. Two of the aims of these experiments were (1) to clarify the basic processes and (2) to apply the beams to material processing. One of the methods was to make thin films of YBCO or C3N4 as examples. Two kinds of KrF and a CO2 laser were planned to be applied to targets ablation. The authors use targets at cryogenic and room temperature, and substrates at cryogenic and high temperature. They also made some numerical simulations of target ablation processes with these lasers. The results will be presented, if they shall have enough minutes during the conference session. They also want to use the beams to simulate wall materials for the future advanced ICF reactors with lasers and Z pinches
