微纳结构中镶嵌微纳梁的制备
Making Micro- and Nano-beams by Channeling in Micro- and Nano-structures
摘要：
非常小截面的粒子束在许多加速器应用中是有用的，包括生物和医学应用。我们展示了在单晶的表面上使用微米尺寸的结构或使用纳米管的沟道技术的能力，以产生横截面低至1平方微米（或纳米）的光束。引导的光束可以被偏转，从而在角度和空间上与初级和散射粒子很好地分离。利用蒙特卡罗模拟对微梁的特性进行了模拟。对于质子和离子，可以实现低至0.1-0.001纳米弧度的发射率和高达每秒每平方微米100万个粒子的通量。
英文摘要：
A particle beam of very small cross-section is useful in many accelerator applications including biological and medical ones. We show the capability of the channeling technique using a micron-sized structure on a surface of a single crystal, or using a nanotube, to produce beam of a cross-section down to 1 square micrometer (or nanometer). The channeled beam can be deflected and thus well separated in angle and space from the primary and scattered particles. Monte Carlo simulation is done to evaluate the characteristics of a channeled microbeam. Emittances down to 0.1-0.001 nanometer radian, and flux up to 1 million particles per square micron per second, can be achieved for protons and ions.
