| Abstract | The QAAS (Quality Assurance and Acceptance System) of superconducting material for RAON's cavities has been set up. The subject was selected by how the part is affected by RF (Radio Frequency) in the cavity operation at cryo-temperature. The QAAS consist of property analysis and checking the surface condition. Each step has criteria its own to pass the assurance and acceptance system. The method to analyze the properties and to inspect the niobium surface was described. The certificates were classified by RRR values of Nb pieces due to distribution of RRR value. The Nb properties slightly different by RRR values, so we will set a bunch of niobium pieces for one specific cavity with Nb pieces having similar RRR value. | |||||
