An H[sup [minus]] current of up 30 mA has been extracted from a 1 cm[sup 2] aperture in a 20 cm diameter volume source with a conical filter field. From a 9.7 cm diameter version of this source, an H[sup [minus]] current of up to 35 mA was extracted from a 0.5 cm[sup 2] aperture. In both sources, the electron-to-H[sup [minus]] ratio is typically [lt]10, and often [lt]5.
