CERN studies on niobium-coated 1.5 GHz copper cavities [PDF]
, 2001 Studies at CERN on niobium-coated 1.5 GHz superconducting cavities are aimed at understanding and possibly curing the causes of the residual resistance increase observed when increasing the accelerating gradient above 15 MV/m. Amongst the possible causes,
