At BNL, work is in progress on the development of a volume production H{sup -} ion source having a toroidally shaped plasma generation region and a conical filter field. With the original, 20 cm diameter source, up to 50 mA of H{sup -} was measured at a current density of 25 mA/cm{sup 2} in pulsed operation. In first results with a version of this source scaled down to 9.7 cm diameter, up to 25 mA of H{sup -} at a current density of 50 mA/cm{sup 2} has been obtained. In both sources the extracted electron current is typically 3--10 times the H{sup -} current.
