Two different origins of the Q-slope problem in superconducting niobium film cavities for a heavy ion accelerator at CERN
Superconducting niobium film cavities deposited on copper substrates (Nb/Cu) have suffered from strong field-dependent surface resistance, often referred to as the Q-slope problem, since their invention. We argue that the Q-slope may not be an intrinsic problem, but rather originates from a combinat...
