Efficient expulsion of magnetic flux in superconducting RF cavities for high applications
S. Posen, A. Grassellino, A. Romanenko +5
Even when cooled through its transition temperature in the presence of an external magnetic field, a superconductor can expel nearly all external magnetic flux. This Letter present…
Cooling Dynamics Through Transition Temperature of Niobium SRF Cavities Captured by Temperature Mapping
M. Martinello, A. Romanenko, M. Checchin +4
Cool-down dynamics of superconducting accelerating cavities became particularly important for obtaining very high quality factors in SRF cavities. Previous studies proved that when…
Magnetic Flux Dynamics in Horizontally Cooled Superconducting Cavities
M. Martinello, M. Checchin, A. Grassellino +4
Previous studies on magnetic flux expulsion as a function of cooling details have been performed for superconducting niobium cavities with the cavity beam axis placed parallel resp…
