In-situ Synchrotron X-Ray Photoelectron Spectroscopy Study of Medium-Temperature Baking of Niobium for SRF Application
Alena Prudnikava, Yegor Tamashevich, Anna Makarova +2
In the present work the chemical composition of niobium surface upon 200-400 °C baking similar to "medium-temperature baking" and "furnace baking" of cavities is explored in-situ b…

Improved RF Performance of Niobium Cavities via In-situ Vacuum Heat Treatment Technique
Yegor Tamashevich, Alena Prudnikava, Alexander Matveenko +3
Vacuum thermal treatments (baking) are known to improve the superconducting properties of the RF surface layer of niobium cavities, and are employed as a last processing step to in…

A model to explain the Q-increase by moderate-temperature treatment in Nb SRF cavities
Yegor Tamashevich, Alena Prudnikava, Jens Knobloch
It is well known that moderate temperature baking of niobium cavities can improve the surface resistance. Presently, it is believed that the diffusion of oxygen into the bulk, resu…
