| description | Ion sources and methods of operating an electromagnet of an ion source for generating an ion beam with a controllable ion current density distribution. The ion source (10) includes a discharge chamber (16) and an electromagnet (42; 42a-d) adapted to generate a magnetic field (75) for changing a plasma density distribution inside the discharge chamber (16). The methods may include generating plasma (17) in the discharge space (24), generating and shaping a magnetic field (75) in the discharge space (24) by applying a current to an electromagnet (42; 42a-d) that is effective to define the plasma density distribution, extracting an ion beam (15) from the plasma (17), measuring a distribution profile for the ion beam density, and comparing the actual distribution profile with a desired distribution profile for the ion beam density. Based upon the comparison, the current applied to the electromagnet (42; 42a-d) may be adjusted to modify magnetic field (75) the magnetic field in the discharge space and, thereby, alter the plasma density distribution. |
