The quality factor (Q{sub 0}) of most of the six LANL {beta} = 0.64 700-MHz 5-cell elliptical cavities starts to drop at E{sub acc} = 8-10 MV/m, which may be related to multipacting. Residual resistances of these cavities were measured to be 5.0-7.6 n{Omega}. The sensitivity of surface resistance to the external magnetic field was measured to be 0.22 n{Omega}/mG. Q disease tests have shown no significant Q{sub 0} degradation for both elliptical cavities and a spoke cavity with our 100 {micro}m BCP.
