Beam sweeping system

The sweeping system deflects high-energy proton and antiproton beams in a single-turn rotating-field magnet that combines deflection in both planes into a single unit. The magnet current has a peak amplitude of 10 kA and the sweep rime is 1.6 /spl mu/s. At the Fermilab Antiproton Source increasing proton beam intensities incident on the antiproton production target threaten to damage the target. The purpose of the sweep magnet is to spread the hot spot on the target with a sweep radius of up to 0.5 mm, greatly reducing the peak energy deposition.
