Latest Development of Electropolishing Optimization for 650 MHz Niobium Cavity
arxiv(2024)
摘要
Electropolishing (EP) of 1.3 GHz niobium superconducting RF cavities is
conducted to achieve a desired smooth and contaminant-free surface that yields
good RF performance. Achieving a smooth surface of a large-sized elliptical
cavity with the standard EP conditions was found to be challenging. This work
aimed to conduct a systematic parametric EP study to understand the effects of
various EP parameters on the surface of 650 MHz niobium cavities used in the
Proton Improvement Plan-II (PIP-II) linear accelerator. Parameters optimized in
this study provided a smooth surface of the cavities. The electropolished
cavity showed significantly a higher accelerating gradient meeting baseline
requirement and qualified for further surface treatment to improve the cavity
quality factor.
