Abstract

A cylindrical single domain superconducting cavity resonator for microwave applications has been made by a net-shape melt processing using YBCO. The quality factor (unloaded Q) has been measured on the cavity sample, below the transition temperature, T/sub o/ in microwave frequencies. Experiments have been carried out to study the dependence of Q on the annealing temperature, as well as the influence of oxygen annealing history on Q value. Other factors, which influence the Q value, are also discussed.
