WE HAVE A SUBSCRIPTION MAILING LIST! Woohoo! If you’re receiving this email, it’s because your email has been added to the list. If you know someone who hasn’t received this email, please send them this link (https://lists.triumf.ca/mailman/listinfo/physical-sciences) so they can subscribe to receive important division updates and other information, but most importantly, notices of our upcoming mixers 😉

If you wish to be removed from the mailing list, no hard feelings – you can do that at the same link above – but I can’t guarantee you won’t miss out 😉

Hope to see you all there!

Science Talk Abstract;

The elemental metal Nb is the de facto material for fabricating superconducting radiofrequency (SRF) cavities, which are common components of particle accelerators. The performance of these devices is intimately linked to the metal's surface treatment, with defects, dopants, and coatings playing important roles. While macroscopic RF testing has long been the key driver of SRF material R&D, developing a better microscopic understanding of these adulterations is needed to advance the field. In this talk, I survey ongoing efforts to improve our "bottom-up" understanding of Nb and its surface adulterations through the use of implanted radioactive spin-probes (e.g., the positive muon or lithium-8). The unique electromagnetic sensitivity and spatial resolution (i.e., depths between 10 to 150 nm) of these beam-based approaches provide unique insight into the nature of Nb's superconductivity and how we may better engineer the metal for SRF applications.
