摘要
最近,放射压力加速(RPA ) 被建议了并且广泛地学习了,它证明那循环地极化了(CP ) 激光脉搏能在 phase-stable-acceleration (PSA ) 加速单音精力充沛的离子捆从 ultrathin 陪衬的方法。自我组织的质子横梁能稳定地在 10 点在和一个平面目标的 CP 激光的相互作用被加速到 GeV,这被发现 < 啜 class= “ a-plus-plus ” > 22 </sup> W/cm < 啜 class= “ a-plus-plus ” > 2 </sup> 。称为紧缩的激光血浆质子加速器(CLAPA ) 的一个工程最近被大多数在中国同意。激光的一个原型驾驶质子加速器(1 ~ 15 MeV/1 Hz ) 将基于 PSA 机制和血浆透镜在下一五年里在北京大学被造。它以后将为惯性的范围熔化为象癌症治疗,血浆成像和快点火那样的应用被升级到 200 兆电子伏。
Recently, radiation pressure acceleration (RPA) has been proposed and extensively studied, which shows that circularly polarized (CP) laser pulses can accelerate mono-energetic ion bunches in a phase-stable-acceleration (PSA) way from ultrathin foils. It is found that self-orgizing proton beam can be stably accelerated to GeV in the interaction of a CP laser with a planar target at 1022 W/cm2. A project called Compact LAser Plasma proton Accelerator (CLAPA) is approved by MOST in China recently. A prototype of laser driven proton accelerator (1 to 15 MeV/1 Hz) based on the PSA mechanism and plasma lens is going to be built at Peking University in the next five years. It will be upgraded to 200 MeV later for applications such as cancer therapy, plasma imaging and fast ignitiou for inertial confine fusion.
