Research in Fundamental Superconducting Radiofrequency (SRF)

这项拨款申请用于支付学生和博士后工资、旅费和运营资金，以支持超导射频(SRF)使用由单独的NSERC RTI资助的基础设施。目标是开发新的加工技术和新材料，以实现在理解和性能方面的突破，同时培养高素质的人员(HQP)。RTI中包括制造两个同轴谐振器的资金，这两个谐振器将用于测试作为加速场和工作频率函数的射频表面电阻。还包括在TRIUMF的β-核磁共振设施中建造一台新的光谱仪的资金，该光谱仪在平行于样品表面的磁场方向具有高磁场能力。该光谱仪将用于表征经过处理的Nb样品以及新的SRF材料，如Nb3Sn和多层材料，作为对muSR[1][2]的表征的补充。这项提案的资金将利用2015年成功获得的RTI资金，并支持学生和博士后实施和操作设备，以实现突破，解决目前SRF社区面临的主要问题。

This grant request is for student and post-doc salaries and travel plus operational funds to support superconducting radiofrequency (SRF) using infrastructure funded through a separate NSERC RTI. The goal is to develop new processing techniques and new materials to achieve a breakthrough in understanding and performance while training highly qualified personnel (HQP). Included in the RTI are funds to fabricate two coaxial resonators that will be used to test rf surface resistance as a function of accelerating field and operating frequency. Also included are funds to construct a new spectrometer in the beta-NMR facility at TRIUMF with high magnetic field capability in a field direction parallel to the sample face. This spectrometer will be used to characterize treated Niobium samples as well as new SRF materials like Nb3Sn and multi-layer materials as a complement to characterizations being done with muSR [1][2]. The funds from this proposal will leverage the RTI funds successfully secured in 2015 and support students and post-docs to implement and operate the equipment to enable breakthroughs that attack the major questions facing the SRF community today.
