摘要
A very small, low power rated H- multicusp source for the 30 MeV compact cyclotron at Swierk was optimized. H- yield in the beam injection line to the cyclotron was measured at different arc powers and plasma electrode potentials. The ion current exceeded 0.5 mA at a steady-state operation. Plasma electron density,temperature and plasma potential in the discharge chamber of the source were measured using a Langmuir probe. The effect of H- current saturation at low are voltage was interpreted on the basis of the plasma diagnostic results.
