Outline of Final Research Achievements

Collisionless shock experiments were conducted using supersonic counter-stream plasmas with parallel double-plane (DP) target. On Gekko XII HIPER laser experiment, collective Thomson scattering ion-term measurement was conducted. Electron and ion temperatures, flow velocity, electron density were measured for counter-streaming plasmas and shock, and their temporal-evolution was investigated.
On OMEGA laser (USA) experiment, Weibel filaments were observed by D-3He fusion produced proton radiography.
On the NIF laser (USA) experiment, DD neutrons/proton and strong x-ray emission from the hot plasmas in the middle of the two planes are observed with CD DP target. These results indicate that neutrons are produced in a shock-heated hot plasma.
