Abstract
IT has been found possible to draw a 10-milliampere current of positive hydrogen ions from a high-frequency discharge maintained at a pressure of about 10-3 mm. A self-sustained discharge cannot be maintained at this pressure with constant potentials even up to 20 kilo-volts, and it is thus possible to use constant potentials of this order to extract positive ions from the discharge and to focus them into a beam. The arrangement is shown in the accompanying diagram.
