Positron Traps and Trap-Based Beams: Status and Future Prospects

摘要

We have developed methods to create cold, dense positron plasmas and cold, bright positron beams using single-component plasma trapping techniques. This paper is an overview of recent work and a look to the future. Applications of these techniques currently being pursued range from studies of atomic and molecular physics and plasma physics to the characterization of surfaces and bulk materials. Examples are briefly discussed.
