Impact of medium temperature heat treatment on flux trapping sensitivity in SRF cavities
Pashupati Dhakal, Bashu Dev Khanal, Eric Lechner +1
The effect of mid-T heat treatment on flux trapping sensitivity was measured on several 1.3 GHz single cell cavities subjected to vacuum annealing at temperature of 150 - 400 $^\ci…
Multi-metallic conduction cooled superconducting radio-frequency cavity with high thermal stability
G. Ciovati, G. Cheng, U. Pudasaini +1
Superconducting radio-frequency cavities are commonly used in modern particle accelerators for applied and fundamental research. Such cavities are typically made of high-purity, bu…
Flux expulsion in niobium superconducting radio-frequency cavities of different purity and essential contributions to the flux sensitivity
Pashupati Dhakal, Gianluigi Ciovati, Alex Gurevich
Magnetic flux trapped during the cooldown of superconducting radio-frequency cavities through the transition temperature due to incomplete Meissner state is known to be a significa…
High Frequency Nonlinear Response of Superconducting Cavity-Grade Nb surfaces
Bakhrom Oripov, Thomas Bieler, Gianluigi Ciovati +9
Nb Superconducting Radio-Frequency (SRF) cavities are observed to break down and lose their high-Q superconducting properties at accelerating gradients below the limits imposed by…
Determination of the magnetic field dependence of the surface resistance of superconductors from cavity tests
J. R. Delayen, H. Park, S. U. De Silva +2
We present a general method to derive the magnetic field dependence of the surface resistance of superconductors from the Q-curves obtained during the cryogenic tests of cavities.…
Effect of Low Temperature Baking in Nitrogen on the Performance of a Niobium Superconducting Radio Frequency Cavity
Pashupati Dhakal, Santosh Chetri, Shreyas Balachandran +2
We report the rf performance of a single-cell superconducting radiofrequency cavity after low temperature baking in a nitrogen environment. A significant increase in quality factor…
