Description

Several superconducting lead cavities in the TM010 mode at 9.7 GHz were investigated at low rf input power (< or approx. =3 mW). The cavities were prepared by deep drawing copper substrates and then depositing lead by means of a new electroplating technique to obtain a continuous film on the inside surface of the cavity. Unloaded Q's on the order of 109 were routinely obtained and the lowest reported residual surface resistance value (2.0 x 10-8Ω) for either TM or TE modes was measured at X-band frequencies
