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…

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…
