Abstract

The Rare Isotope Accelerator project involves generating heavy element ion beams for use in a fragmentation target line to produce selected ion beams for physics research experiments. The main beam and fission fragments, after passing through the target, are collected and passed along by a series of collecting magnets and a dipole magnet. In the first dipole magnet, the main beam impacts onto a beam dump located on each side of the magnet vacuum chamber. A dump design that involves rotating cylinders and internal water cooling passages has been designed to absorb the glancing impact of the main beam. The beam power designed for is 100 kW and water cooling is by turbulent sub-cooled forced convection.
