Description

This article describes a system for rapidly sweeping a high-energy particle beam in a circular path on a target. The sweeping system deflects the beam in a single-turn rotating-field magnet that combines deflection in both planes into a single unit. The magnet current is up to 10 kA in amplitude and the sweep time is 1.6 {micro}s. The magnet consists of 4 conductors twisted to provide a uniform line-integral deflecting magnetic field, arranged inside a pressed-powder magnetic core. The pulsed power supply provides the current to the high radiation area of the target vault through several meters of stripline and ... continued below

Description

This article describes a system for rapidly sweeping a high-energy particle beam in a circular path on a target. The sweeping system deflects the beam in a single-turn rotating-field magnet that combines deflection in both planes into a single unit. The magnet current is up to 10 kA in amplitude and the sweep time is 1.6 {micro}s. The magnet consists of 4 conductors twisted to provide a uniform line-integral deflecting magnetic field, arranged inside a pressed-powder magnetic core. The pulsed power supply provides the current to the high radiation area of the target vault through several meters of stripline and coaxial cable by means of a magnetic pulse compression circuit based on saturing Ni-Fe and Metglas tape cores. At the Fermilab Antiproton Source increase proton beam intensities incident on the antiproton production target threaten to deliver energy densities sufficient to locally melt the target in a single pulse. 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.
