反氢产生的正电子等离子体诊断和温度控制
Positron plasma diagnostics and temperature control for antihydrogen production
摘要：
通过将反质子与冷的、受限的正电子等离子体混合来产生反氢原子，关键取决于等离子体密度和温度等参数。我们讨论了非破坏性的测量，基于一种新的，实时分析的激发，低阶等离子体模式，提供了全面的表征ATHENA反氢装置中的正电子等离子体。得到了等离子体的长度、半径、密度和总粒子数。讨论了等离子体温度变化的测量和控制，以及在反氢产生实验中的应用。
英文摘要：
Production of antihydrogen atoms by mixing antiprotons with a cold, confined, positron plasma depends critically on parameters such as the plasma density and temperature. We discuss non-destructive measurements, based on a novel, real-time analysis of excited, low-order plasma modes, that provide comprehensive characterization of the positron plasma in the ATHENA antihydrogen apparatus. The plasma length, radius, density, and total particle number are obtained. Measurement and control of plasma temperature variations, and the application to antihydrogen production experiments are discussed.
