PROBLEM TO BE SOLVED: To disclose an ion source assembly 10. SOLUTION: The assembly comprises a source sub-assembly having an ion source 20, a lead-out electrode 40 and an electrically insulating high voltage bushing 60 to support the lead-out electrode 40 relative to the ion source 20. The ion source assembly further includes a chamber 70 having an exit aperture to allow egress of ions to an ion implanter. The chamber 70 encloses one or more further electrodes 80, 90. The source sub-assembly is mounted to the chamber 70 via a hinge 150. This allows ready access to the inner walls of the chamber 70, which in turn allows easier maintenance and cleaning of the further electrodes 80, 90 as well as the inner walls of the chamber 70. Preferably, a liner 160 is employed on the inner walls of the chamber 70.
