【Abstract】 In this paper, the thermal break down of superconducting cavity is introduced and the relation between the possible maximum magnetic field and RRR value is discussed. A kind of nondestructive RRR detection technique-Eddy Current method and its experimental setup are also introduced. Finally, some results of RRR test for two kinds of Niobium materials are presented.更多还原
