标题： Design of a Unique Open-Geometry Cylindrical Penning Trap

摘要： 德克萨斯A&M大学Penning阱设施是一个即将建成的离子阱，将用于搜索T=2超允许的$\beta$延迟质子衰变中的可能标量电流，如果发现这些电流，将表明存在超出标准模型的物理现象。 此外，TAMUTRAP将为回旋加速器研究所的各种其他应用提供低能、点状的离子源。 该实验围绕一个独特的、补偿的圆柱形Penning阱展开，该阱采用了一种特殊的优化$\mathrm{length}/\mathrm{radius}$电极结构比例，其他设施并未使用该比例。 这使得几何结构能够表现出前所未有的90毫米自由半径，比任何现有陷阱都更大，同时保持可处理的整体长度。 该阱的几何结构是从基本原理设计的，适用于各种核物理实验。 特别是，电极结构既“可调节”又“正交化”，这使得阱中心能够产生接近四极电场，这是进行精确质量测量所必需的特性。 显示英文摘要

摘要： The Texas A&M University Penning Trap facility is an upcoming ion trap that will be used to search for possible scalar currents in T=2 superallowed $\beta$-delayed proton decays, which, if found, would be an indication of physics beyond the standard model. In addition, TAMUTRAP will provide a low-energy, point-like source of ions for various other applications at the Cyclotron Institute. The experiment is centered around a unique, compensated cylindrical Penning trap that employs a specially optimized $\mathrm{length}/\mathrm{radius}$ ratio in the electrode structure that is not used by any other facility. This allows the geometry to exhibit an unprecedented 90 mm free radius, which is larger than in any existing trap, while at the same time remaining a tractable overall length. The trap geometry was designed from first principles to be suitable for a wide range of nuclear physics experiments. In particular, the electrode structure is both "tunable" and "orthogonalized", which allows for a near quadrupole electric field at the trap center, a feature necessary for performing precision mass measurements.
