Description

The highest gradient with niobium sc rf cavities at beta = 1 was viewed historically. There is no progress from 40 MV/m since 1995. Is this due to no finding breakthrough technology, or does it mean a theoretical field limitation? In this paper, the best results are compared to the lower critical magnetic field (Hcl) or superheating field of niobium material measured in KEK, The highest 40 MV/m might be the upper limitation from Hcl of niobium material.
