摘　　要：　给出用"闪光二号"加速器高功率离子束轰击19F靶产生6～7MeV准单能脉冲γ射线的实验结果;提出采用离子束传输法分离和降低轫致辐射干扰的方法,利用闪烁体探测器和半导体探测器,测出质子传输不同距离后轰击C2F4靶产生的6～7MeV准单能脉冲γ射线信号以及相比轫致辐射的延迟时间;介绍了模拟材料的软X射线的热 力学效应等方面的高功率离子束的应用,给出一些实验和理论计算结果。The results obtained in the theoretical and experimental studies for the application of high power ion beams in certain areas of nuclear physics and material science are reported. The preliminary experimental results of generating 6-7 MeV quasi-monocnergetic pulsed γ-rays with high power pulsed proton beams striking 19F target on the Flash II accelerator are presented. By placing the target far enough downstream, the quasi-monoenergetic pulsed γ-rays can be discriminated from the diode bremsstrahlung. This article also describes the other applications of high power ion beams and the preliminary experimental and theoretical results in simulation of soft X-ray thermal-mechanical effects, generation of high intense pulsed neutrons, equation of state and shock-wave physics experiments, surface modification and so on.
