Abstract
A system for controlling a high-power ion beam is disclosed, such as for steering, measuring, and/or dissipating the beam's power. In one embodiment, the ion beam can be controlled by being imparted into a cylindrical tube (e.g., a faraday cup), and deflected to strike an interior tube wall at an angle, thereby increasing an impact area of the beam on the wall. By also rotating the deflected beam around a circumference of the interior wall, the impact area of the ion beam may be further increased, thereby absorbing (dissipating) the high-power ion beam on the wall. In another embodiment, the ion beam may be passed through first, second, and third adjustable magnetic rings. By adjusting a relative angle between the rings and a combined rotation angle of all of the rings, a deflected ion beam may be rotated around a circumference of the interior wall of a power-absorbing tube, accordingly.
