Summer 2002. Dc H^- ion beam of 5 mA was obtained and investigated on the model of negative ion source with Penning geometry electrodes. The value measured for the normalized emittance 0.3 p mm mrad meets the requirements.

Tandem negative hydrogen ion source

A new concept for a dc 50 mA negative ion source was proposed.
