1. Fermilab

Electro-chemical Polishing (EP) is one of the key technologies of surface treatments for niobium superconducting cavities. Fermilab has established cold EP method and applied on all single cell cavities (1.3 GHz~3.9 GHz) processed at Fermilab EP facility. Cold EP method allows achieving continuous large current oscillations during EP process and providing the uniform removal over the cell with the variation of ±15%. Here we report details of Fermilab EP facility and cold EP method in this paper.
