We report the H beam currents and emittances produced when Penning Surface-Plasma Sources (SPS), equipped with circular emitters, are pulsed at /approximately/1% duty factor. Two sources are now under investigation: the small-angle source (SAS) and the 4X source. The 4X source is designed to test the plasma scaling laws for Penning SPS; SAS is the 1X device. The 0.16 cmT discharge volume of the SAS is /approximately/30 times smaller than that of the 4X source, 4.6 cmT. With a 0.25-cm-diam circular emitter, the SAS produces 82 mA of 27-keV H beam with normalized rms emittance of 0.0053 x 0.0056 ( /center dot/cm/center dot/mrad)S. With a 0.26-cm-diam circular emitter, the 4X source produces 50 mA of 29-keV H beam with emittance of 0.0049 x 0.0050 ( /center dot/cm/center dot/mrad)S. The measured data are compared with the predictions of the ion-optical code SNOW. 10 refs., 7 figs., 1 tab.
