Beam parameters have been measured for both the Surface Ionization with Transverse Extraction (SITEX) and Volume Ionization with Transverse Extraction (VITEX) H/sup -//D/sup -/ ion sources. Both sources use a reflex discharge to generate the main plasma. Beam energies up to 18 keV were used for pulse lengths up to several seconds. For SITEX, Faraday cup magnetically analyzed D/sup -/ beam currents of 110 mA at extraction densities of 48 mA/cm/sup 2/ and at a source ion temperature of 4 eV have been measured. For the VITEX results, Faraday cup magnetically analyzed beam currents of up to 80 mA at extraction densities of 27 mA/cm/sup 2/ and at a source ion temperature of 0.5 eV have been measured. Virtually all extracted electrons were recovered at an energy of 10--30% of the accel beam energy, and there were none in the analyzed beam.
