Impact of metallographic polishing on the RF properties of Niobium for SRF applications
Oleksandr Hryhorenko, Anne-Marie Valente-Feliciano, David Longuevergne +6
The performance of superconducting radio-frequency (SRF) cavities made of Niobium is tied to the quality of their inner surfaces exposed to the radio frequency (RF) waves. Future s…
