This RUI project focuses on the study of toroidal electron plasma confinement with the following goals: 1) To design and build a toroidal electron plasma confinement device with a one kG confining magnetic field, better vacuum conditions than any previous device of its kind, and field symmetry comparable to cylindrical electron plasma experiments that demonstrate confinement times of minutes or hours, 2) to successfully confine toroidal electron plasmas in a (partially) toroidal trap for times longer than 50 milliseconds, longer than any prior experiment of its type, and permitting detailed investigation of equilibrium, stability and transport physics, 3) o observe the theoretically predicted magnetic pumping transport mechanism, a transport mechanism that results from toroidal effects, and 4) to develop a charge injection (and plasma diagnostic) strategy for use in a completely toroidal trap, opening up the possibility of studying electron plasma configurations with parallel current. The activity provide research experiences, as well as scientific authorship and presentation opportunities, for undergraduate students

本RUI项目主要研究环面电子等离子体约束，目标如下：1)设计并建造一个环形电子等离子体约束装置，该装置具有1 kG的约束磁场，比以往任何同类装置都更好的真空条件，并且具有与圆柱形电子等离子体实验相媲美的场对称性，证明约束时间为几分钟或几小时；2)成功地将环形电子等离子体限制在（部分）环形陷阱中，时间超过50毫秒，比以往任何同类实验都长。并且允许对平衡，稳定性和输运物理进行详细的研究，3)观察理论上预测的磁泵输运机制，这是一种由环面效应产生的输运机制，4)开发用于完全环面陷阱的电荷注入（和等离子体诊断）策略，开辟了研究平行电流下电子等离子体结构的可能性。该活动为本科生提供研究经验，以及科学写作和演讲的机会
