Preliminary research results for generation and application of high power ion beams on FLASH II accelerator

Preliminary results for the generation and application of the high power ion beam(HPIB) on the FLASH II accelerator are reported. The structure and principle of the pinch reflex ion beam diode are introduced. The equation of parapotential flow is corrected for the reduction of diode A-K gap due to the motion of cathode and anode plasma. The HPIB peak current of similar to 160kA is obtained with a peak energy of similar to 500keV. Experimental investigations of generating 6-7MeV quasi-monoenergetic pulsed gamma-rays with high power ion(proton) beams striking F-19 target are presented. In addition, the results of the thermal-mechanical effects on the material irradiated with HPIB, which are applied to the simulation of 1 keV black body radiation x-rays, are also discussed.
