Research in Fundamental Superconducting Radiofrequency (SRF)

这项拨款申请是为学生和博士后的工资和旅行加上运营资金，以支持超导射频（SRF）使用基础设施，通过单独的NSERC RTI资助。目标是开发新的加工技术和新材料，在培养高素质人才（HQP）的同时，在理解和性能方面取得突破。RTI中包括制造两个同轴谐振器的资金，用于测试射频表面电阻作为加速场和工作频率的函数。还包括在TRIUMF的β -核磁共振设施中建造一个新的光谱仪的资金，该光谱仪在平行于样品面的磁场方向上具有高磁场能力。该光谱仪将用于表征处理过的铌样品，以及新的SRF材料，如Nb3Sn和多层材料，作为对用muSR[1][2]进行表征的补充。该提案的资金将利用2015年成功获得的RTI资金，支持学生和博士后实施和操作设备，以实现突破，解决SRF社区今天面临的主要问题。

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.
