摘要:
St. Benedict离子捕获系统旨在测量超允许-混合镜跃迁中的β-ν角相关参数,该系统正在 Notre Dame 大学建设中。这些测量将提供大量数据以提高 CKM 矩阵中 V_ud 元素的准确性。该系统的一个主要组件是射频四极子冷却-压缩器,用于生成低发散率的离子束以注入测量 Paul 捕获器。使用钾离子源对冷却-压缩器进行离线调试,确定该设备能够产生具有 50 纳秒全宽半高响应时间宽度的冷却离子束。调试结果还确定了捕获效率为 93(1)%,捕获半衰期为 20.0(5) 秒。
英文摘要:
The St. Benedict ion trapping system, which aims to measure the $β-ν$ angular correlation parameter in superallowed-mixed mirror transitions, is under construction at the University of Notre Dame. These measurements will provide much-needed data to improve the accuracy of the $V_{ud}$ element of the CKM matrix. One of the major components of this system is the radio frequency quadrupole cooler-buncher, which is necessary to create low-emittance ion bunches for injection into the measurement Paul trap. The off-line commissioning of the cooler-buncher, using a potassium ion source, determined that the device could produce cooled ion bunches characterized by a 50-ns full-width-half-maximum time width. The commissioning results also determined the trapping efficiency to be 93(1)$\%$ and the trapping half-life to be 20.0(5) s.
