Abstract:
1. A method of qualifying niobium and/or other super conducting materials suitable for the reliable fabrication of SCRF cavities, which will invariably deliver the desired high accelerating field corresponding to the respective superconducting material comprising: identification of both the best superconducting lower critical field H (i) measuring the H (ii) subjecting the sample to mechanical stress and noting the variations/effects thereof if any, in the H (iii) annealing the sample at various temperatures and noting the changes in the H (iv) subjecting the sample to chemical treatments and noting the variations in the H (v) subjecting the chemically treated sample to baking/annealing and noting the variations in the H (vi) measuring the thermal conductivity with the best identified H
