Establishing Limits for Positron Plasmas -- Long Term Storage, High Densities, and Cold Beams

涉及正电子（即电子的反粒子）的现象在许多领域都很重要，包括天体物理学、等离子体和原子物理学以及材料科学。通过利用非中性等离子体技术的实验室实验，最近在这些领域取得了很大进展。本提案描述了一个研究计划，以创建和理解参数空间新区域中单组分正电子等离子体的新状态的物理学。反过来，这些反物质等离子体将用于一系列科学和技术应用。

Phenomena involving positrons (i.e., the antiparticles of electrons) areimportant in many fields including astrophysics, plasma and atomic physics, and materialsscience. Much progress has been made recently in these areas through laboratory experimentsthat exploit nonneutral plasma techniques. This proposal describes a program of research tocreate and understand the physics of novel states of single-component positron plasmas in newregions of parameter space. These antimatter plasmas will be used, in turn, for a range ofscientific and technological applications.
