摘要：
The authors describe a plasma ion source that is based on low-voltage low-pressure hollow-cathode discharge in a magnetic field. The ions from the discharge plasma are extracted through a wide aperture in the emitter cathode without the use of a screen to stabilize the emitting plasma surface. The aperture area is equal to the cross-sectional area of the widest discharge region. An ion beam with a current of 0.2 A is obtained with an accelerating potential of 10 kV and a discharge current of 2 A.
