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 - 160 kA is obtained with a peak energy of -500 keV. Experimental investigations of generating 6-7 MeV quasi-monoenergetic pulsed γ-rays with high power ion (proton) beams striking 19F 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.
