英文摘要	We report a high-performancepulsed optically pumped (POP) Rb clock based on a novel magnetrontype microwave cavity. The cavity has a volume of 30 mL, enabling a highly homogenous microwave field distribution. With the laser frequency tuning to the ground-state hyperfine level F = 2 of the D2 line, we observe a Ramsey fringe contrast of 52% in terms of optical absorption detection. The resultant shot noise limit is estimated to be 1.6 x 10(-14) tau(-1/2). The clock frequency stability is measured as 2.3 x 10(-13) tau(-1/2) (1-100 s), which is limited by the relative intensity noise of the light.
