Activities related to Microstructural Studies of Nb3Sn Coatings for SRF Cavities

Due to limited microcopy capabilities at Fermilab, the PI has approached Professor David Seidman’s group at Northwestern University to collaborate for this work. A postdoctoral associate from Dr. Seidman’s group will spend six person-months dedicated to study of Nb3Sn films from Fermilab, including the microscopy studies described above. The postdoctoral associate will engage closely with the PI, Dr. Posen, who will guide the studies and generate samples to perform microscopic analysis on. The activities carried out by the postdoctoral associate may also include development of techniques to remove a small amount of material from the coatings without affecting their superconducting RF properties.
