| description | The invention belongs to the technical field of ion beam machining, and particularly relates to high-efficiency low-damage defect surface ion beam polishing equipment and method. The equipment comprises an ion beam polishing equipment chamber and an ion source system, wherein a workpiece is mounted in the ion beam polishing equipment chamber; the ion source system is connected with the radio frequency power supply, the bias power supply and the lead-out power supply; according to the method, after fused quartz is selected as a workpiece to be fixed, the normal direction of the machined surface of the workpiece is parallel to the incident direction of an ion beam, an equipment cavity is closed and vacuumized, working gas is introduced, the working gas is excited and ionized, high-density plasma is generated, and meanwhile a bias power supply and extraction voltage are started; and bombarding the surface of the workpiece by using a multi-component ion beam formed by alternately led-out positive and negative ion |
