BNL volume H{sup {minus}} sources

Conference ·
OSTI ID:10167289
An H{sup -} 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 -} current of up to 35 mA was extracted from a 0.5 cm{sup 2} aperture.In both sources, the electron-to-H{sup -} ratio is typically < 10, and often < 5.
