High Thermal Conductivity Cryogenic RF Feedthroughs for Higher Order Mode Couplers
Proceedings of the 2005 Particle Accelerator Conference
The use of higher-order-mode (HOM) pickup probes in the presence of significant fundamental RF fields can present a thermal challenge for CW or high average power SRF cavity applications. The electric field probes on the HOM-damping couplers on the JLab "High Gradient" (HG) and "Low Loss" (LL) seven-cell cavities for the CEBAF upgrade are exposed to approximately 10% of the peak magnetic field in the cavity. To avoid significant dissipative losses, these probes must remain superconducting
