Theory design of proton imaging magnetic lens for hot spot measurement in inertial confinement fusion

摘要: 根据加速器束流输运线设计的比例定律，设计了适用于ICF内爆DD反应产生的3.6 MeV准单能质子束成像的磁透镜系统。通过公式推导以及束流动力学追踪模拟，获得了类似于几何光学成像中的物像关系，并使用三维粒子追踪模拟验证了磁透镜成像的物像关系。物像关系的满足，使得可以对磁透镜系统进行封装，然后根据物像关系, 选择不同的物距以及相应的相距, 就可以对物体成不同大小的像。Abstract: The magnetic lens used in high energy proton radiography system can alleviate the degradation of resolution which is induced by multi scattering of protons. A magnetic lens used for 3.6 MeV protons produced from DD fusion reactions in the implosion region is designed based on the scaling law of beamline design. A similar object-image relationship as in geometrical optical is deduced. 3D particle tracing simulation is also carried out to demonstrate the object-image relationship of the magnetic lens.
