The Rise of Ingot Niobium as a Material for Superconducting Radiofrequency Accelerating Cavities
P. Kneisel, G. Ciovati, P. Dhakal +4
As a result of a collaboration between Jefferson Lab and niobium manufacturer CBMM, ingot niobium was explored as a possible material for superconducting radiofrequency (SRF) cavit…
Status Report on Multi-Cell Superconducting Cavity Development for Medium-Velocity Beams
W. Hartung, C. C. Compton, T. L. Grimm +3
Three prototype 6-cell superconducting cavities for acceleration in the velocity range of 0.40 to 0.53 times the speed of light have been fabricated. The quality factor (Q) of the…
Investigations of surface quality and SRF cavity performance
G. Wu, M. Ge, P. Kneisel +4
Magnetic field enhancement has been studied in the past through replica and cavity cutting. Considerable progress of niobium cavity manufacturing and processing has been made since…
The Continuous Electron Beam Accelerator Facility at 12 GeV
P. A. Adderley, S. Ahmed, T. Allison +136
This review paper describes the energy-upgraded CEBAF accelerator. This superconducting linac has achieved 12 GeV beam energy by adding 11 new high-performance cryomodules containi…
Low temperature laser scanning microscopy of a superconducting radio-frequency cavity
G. Ciovati, Steven M. Anlage, C. Baldwin +10
An apparatus was developed to obtain, for the first time, 2D maps of the surface resistance of the inner surface of an operating superconducting radio-frequency niobium cavity by a…
