Abstract: (4508 Views)
In this paper, we optimized the magnetic-field configuration for a penning ion source by using permanent magnets. This ion source is designed for a 200keV electrostatic accelerator. By simulating particle behavior in the ion source with CST particle studio, the appropriate magnets design parameters has been optained.The purpose of this design is to increase the effieciency of the ion source by producing a dense plasma that affect the beam characteristict. The designed magnetic system consist of two ring magnets around the anode at the same distance from each other.the arrangement of the magnetic field behaves like a magnetic mirror that causes to trap more particle inside the source. So the particle density increase before plasma formation that causes to organization of more dense plasma.
