Frequency dependence of trapped flux sensitivity in SRF cavities
Mattia Checchin, Martina Martinello, Anna Grassellino +6
In this letter, we present the frequency dependence of the vortex surface resistance of bulk niobium accelerating cavities as a function of different state-of-the-art surface treat…
Advancement in the understanding of the field and frequency dependent microwave surface resistance of niobium
M. Martinello, S. Aderhold, S. K. Chandrasekaran +6
The radio-frequency surface resistance of niobium resonators is incredibly reduced when nitrogen impurities are dissolved as interstitial in the material, conferring ultra-high Q-f…
Unprecedented Quality Factors at Accelerating Gradients up to 45 MV/m in Niobium Superconducting Resonators via Low Temperature Nitrogen Infusion
A. Grassellino, A. Romanenko, Y. Trenikhina +9
We report the finding of new surface treatments that permit to manipulate the niobium resonator nitrogen content in the first few nanometers in a controlled way, and the resonator…
