基于捕获的新型正电子束及应用

TRAP-BASED POSITRON BEAM TECHNIQUE AND ITS APPLICATIONS

基于捕获的新型正电子束技术是通过潘宁阱中捕获、约束和积累正电子而发展的新一代正电子束技术。本文介绍正电子的捕获、冷却,压缩技术,基于捕获的正电子束形成技术,以及该技术将来发展展望,最后讨论该技术在原子物理学和材料科学等多个领域的应用。

A new generation of positron beams in the form of trap-based beam sources has been developed by positron trapping, confinement and accumulation in a Penning trap. In this article we describe positron trapping, positron cooling, positron compression and beam formation techniques using traps. Then we discuss the future prospects for positron trapping and beam formation. Finally, we describe the applications of trap-based beam techniques in various areas of science and technology such as atomic physics and materials science.
