Role of microstructure on flux expulsion of superconducting radio frequency cavities
B. D. Khanal, S. Balachandran, S. Chetri +8
The trapped residual magnetic flux during the cool-down due to the incomplete Meissner state is a significant source of radio frequency losses in superconducting radio frequency (S…
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…
Field, frequency and temperature dependence of the surface resistance of nitrogen diffused niobium superconducting radio frequency cavities
P. Dhakal, B. D. Khanal, A. Gurevich +1
We report the RF performance of several single-cell superconducting radio-frequency cavities subjected to low temperature heat treatment in nitrogen environment. The cavities were…
Temperature, RF Field, and Frequency Dependence Performance Evaluation of Superconducting Niobium Half-Wave Cavity
N. K. Raut, B. D. Khanal, J. K. Tiskumara +4
Recent advancement in superconducting radio frequency cavity processing techniques, with diffusion of impurities within the RF penetration depth, resulted in high quality factor wi…
Quench Detection in a Superconducting Radio Frequency Cavity with Combine Temperature and Magnetic Field Mapping
B. D. Khanal, P. Dhakal, G. Ciovati
Local dissipation of RF power in superconducting radio frequency cavities create so called hot spots, primary precursors of cavity quench driven by either thermal or magnetic insta…
Evaluation of flux expulsion and flux trapping sensitivity of srf cavities fabricated from cold work Nb sheet with successive heat treatment
B. D. Khanal, P. Dhakal
The main source of RF losses leading to lower quality factor of superconducting radio-frequency cavities is due to the residual magnetic flux trapped during cool-down. The loss due…
