Nitrogen-Doped 9-Cell Cavity Performance in a Test Cryomodule for LCLS-II
Dan Gonnella, Ralf Eichhorn, Fumio Furuta +13
The superconducting RF linac for LCLS-II calls for 1.3 GHz 9-cell cavities with an average intrinsic quality factor Q0 of 2.7x10^10 at 2 K and 16 MV/m accelerating gradient. Two ni…
Thermocurrents and their Role in high Q Cavity Performance
R. Eichhorn, C. Daly, F. Furuta +12
Over the past years it became evident that the quality factor of a superconducting cavity is not only determined by its surface preparation procedure, but is also influenced by the…
On superconducting niobium accelerating cavities fired under N2-gas exposure
Ralf Eichhorn, Daniel Gonnella, Georg Hoffstaetter +2
The dependence of the Q-value on the RF field (Q-slope) is actively studied in various accelerator laboratories. Although remedies against this dependence have been found, the phys…
