The successful high current, long-pulse SITEX source experiments with H/sup -/ beams have been extended to D/sup -/ operation and to short-pulse H/sup -/ and D/sup -/ beam acceleration. Extracted D/sup -/ beam current densities of 100 mA/cm/sup 2/ at the plasma grid have been achieved for 3 s at a total beam of 260 mA and 10 keV. The extracted electron-to-D/sup -/ ratio is < 5% with roughly-equal 100% of the extracted electrons collected at 2 keV. Short-pulse beams down to 10 ms in length have been accelerated with the minimum pulse length determined by the power supply time constants. Optics of the accelerated beam is theta(1/e)/sub perpendicular/ = +- 0.48/sup 0/, which corresponds to a normalized emittance perpendicular to the slot of 0.0007..pi.. cm-mrad. These data place an upper limit on the surface conversion D/sup -/ ion temperature of 0.7 eV.
