Direct extraction H- ion source
Description
A direct extraction H- ion source of the Penning design described by Dudnikov was built and tested. To date a beam of 108 mA was extracted from a 10 x 0.5 mm2 slit and transported through a 900 bending magnet into a Faraday cup at a duty factor of approximately 7 Hz x 700 μs (0.5 percent). The duty factor limitation is imposed by operating temperature requirements so that at reduced arc current a dc beam of 4 mA was reached
