| Abstract: | The influence of magnetic field on plasma parameters in a magnetic mu-Itipole line-cusp argon ion source are studied.It is shown that the electrons in the discharge chamber consist of two components having different temperature Maxwellium distributions when discharge voltage is less than 50V,Low magnetic field has little effect on the movement of ions,and ions flow nearly isotropically from the ion production region within the chamber.However,ions will be confined to some extent when the magnetic field is higher than 900G.In this case,the ion leakage width through a cusp is approximately equal to twice the ion gyroradius. |
