Accelerating fields up to 49 MV/m in TESLA-shape superconducting RF niobium cavities via 75C vacuum bake
A. Grassellino, A. Romanenko, D. Bice +9
In this paper we present the discovery of a new surface treatment applied to superconducting radio frequency (SRF) niobium cavities, leading to unprecedented accelerating fields of…
Commissioning And First Results From The Fermilab Cryomodule Test Stand
E. R. Harms, M. Awida, C. Baffes +34
A new test stand dedicated to Superconducting Radiofrequency (SRF) cryomodule testing, CMTS1, has been commissioned and is now in operation at Fermilab. The first device to be cool…
The Effect of Mechanical Cold Work on the Magnetic Flux Expulsion of Niobium
S. Posen, S. K. Chandrasekaran, A. C. Crawford +5
Expulsion of ambient flux has been shown to be crucial to obtain high quality factors in bulk niobium SRF cavities. However, there remain many questions as to what properties of th…
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…
