Development of Printed Circuit Board Radio Frequency Quadrupole (PCB RFQ) Ion Traps for High Precision Mass Spectrometry

我们建议利用印刷电路板技术开发新型的离子陷阱。选择印刷电路板制造，而不是传统制造，使这些新型离子陷阱具有精确度、坚固性和成本效益。第一批原型已经在爱丁堡大学建造并委托使用。一个悬而未决的挑战是这些新离子陷阱的放气和真空行为。在这笔赠款中，我们要求提供资金，以系统地研究建造离子陷阱原型的性能。研究结果将为基于PCBRFQ的新型RFQ束线和注入陷阱的开发和建设提供指导。新系统将提高GSI的FRS离子捕捉器的灵敏度和分辨率，并能够在核结合的极限下对非常奇异的核进行新的质量测量。这将给我们提供对原子核结构的洞察，并塑造我们对原子核的理解。

We propose to develop novel types of ion traps using printed circuit board technology. Choosing PCB manufacturing over traditional manufacturing makes these novel ion traps precise, robust and cost effective. First prototypes have been build and commissioned at the University of Edinburgh. An open challenge is the outgassing and vacuum behaviour of those new ion traps. In this grant we request funds to systematically investigate the performance of the prototype ion trap build. The results will guide the development and construction of a new RFQ beam line and injection trap based on PCB RFQs. The new system will boost the sensitivity and resolving power of the FRS Ion Catcher at GSI and enable new mass measurements of very exotic nuclei at the limits of nuclear binding. This will give insights into nuclear structure and shape our understanding of the atomic nucleus.
