摘　　要：主要给出了“闪光二号”加速器高功率离子束 (HPIB)产生及应用研究的初步结果 .介绍了强箍缩反射离子束二极管的结构及工作原理 ,给出了考虑阴阳极产生的等离子体运动对二极管间隙影响的饱和顺位流修正公式 .实验得到的离子束峰值能量约 5 0 0keV ,峰值电流约 16 0kA .介绍了利用高功率离子束 (质子束 )轰击1 9F靶产生 6— 7MeV准单能脉冲γ射线的初步实验结果 ,给出了利用高功率脉冲离子束模拟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 ～160kA is obtained with a peak energy of ～500keV. Experimental investigations of generating 6—7MeV 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 1keV black body radiation x-rays, are also discussed.
