摘要：
A Penning surface-plasma source (SPS) discharge chamber was enlarged 4X in two dimensions. To date, three pulsed discharge modes have been studied: two with noisy arcs ( APP GRTH 20% H- current fluctuations) and one with a quiescent arc ( APP GRTH 1% H- current fluctuations). Lower arc magnetic field and higher H//2 gas flow allow switching from the noisy to the quiescent mode. The noisy modes yield up to 120 mA of 29-keV H- beam; for 110 mA at 29 keV, the two-dimensional normalized rms emittance is 0. 017 multiplied by 0. 018 pi -cm-mrad. The quiescent mode yields 75 mA of 29-keV (H- beam; for 67 mA at 24 keV, the emittance is 0. 011 multiplied by 0. 012 pi -cm-mrad.
