Deflection of High-Energy Cosmic Radiation Ions using a Bent Crystal Shield
摘要：
本文介绍了一种利用离子沟道效应使所有原子序数的宇宙辐射离子偏离航天器的弯曲晶体屏蔽。它的重，高能量离子的透射角分布的影响，其特征在于使用Monte Carlo沟道模拟。达到由弯曲晶体曲率半径设定的能量极限的离子被全曲率角偏转。一个弯曲的晶体屏蔽与1 × 1厘米2的表面积能够偏转这样的离子与能量高达100 GeV/核子的制造，其中在整个入口表面的晶格平面均匀对齐。
英文摘要：
A bent crystal shield which is capable of deflecting cosmic radiation ions of all atomic numbers away from spacecraft using the ion channeling effect is described. Its effect on the transmitted angular distribution of heavy, high-energy ions is characterized using Monte Carlo channeling simulations. Ions up to an energy limit set by the bent crystal curvature radius are deflected by the full curvature angle. A bent crystal shield with a 1 x 1 cm2 surface area capable of deflecting such ions with energies up to 100 GeV/nucleon is fabricated in which the lattice planes across the entrance surface are uniformly aligned.
