This award is made in response to a proposal submitted to and reviewed under the NSF-DoE Partnership in Plasma Science and Engineering joint solicitation, NSF 09-596. The award provides funds to support undergraduate participation in the overall research effort, which is being funded separately by the DoE Award No. DE-FG02-10ER55080.1Cold antimatter is important in a range of applications. This project will develop new physics tools for antimatter research. Cyclotron cooling of positrons has proven to be an effective and useful tool. The limits of this technique and methods to improve cooling rates will be explored. The rotating wall technique, whereby rotating electric fields are used to compress plasmas radially inward across the magnetic field, has proven to be an exceedingly useful way to achieve high plasma densities and long confinement times. Research will be conducted to find improved ways to compress plasmas and to form cold high-density states. Additionally, a method will be developed to form specially tailored (e.g., cold, bright) positron beams from trapped plasmas, including beams extracted from the magnetic field of the Penning-Malmberg trap. The undergraduate participation, enabled by this award, adds a broader educational impact through the early-year training of students by introducing them to scientific research as a possible career path.

该奖项是为了响应向 NSF-DoE 等离子体科学与工程合作伙伴联合征集 (NSF 09-596) 提交并审查的提案而颁发的。该奖项提供资金支持本科生参与整个研究工作，该研究工作由美国能源部奖号 DE-FG02-10ER55080.1 单独资助。1冷反物质在一系列应用中非常重要。该项目将为反物质研究开发新的物理工具。 正电子回旋冷却已被证明是一种有效且有用的工具。 将探讨该技术和提高冷却速率的方法的局限性。 旋转壁技术，利用旋转电场在磁场中径向向内压缩等离子体，已被证明是实现高等离子体密度和长限制时间的极其有用的方法。将进行研究以找到压缩等离子体和形成冷高密度态的改进方法。 此外，还将开发一种方法，从捕获的等离子体中形成专门定制的（例如，冷的、明亮的）正电子束，包括从彭宁-马尔姆伯格陷阱的磁场中提取的束。通过该奖项，本科生的参与通过对学生的早期培训增加了更广泛的教育影响，向他们介绍科学研究作为可能的职业道路。
