High field Q slope and the effect of low-temperature baking at 3 GHz

A strong degradation of the unloaded quality factor with field, called high field Q slope, is commonly observed above B_{p}≅100  mT in elliptical superconducting niobium cavities at 1.3 and 1.5 GHz. In the present experiments several 3 GHz niobium cavities were measured up to and above B_{p}≅100  mT...
