The IUCF Cooler-A Storage Ring with Electron Cooling for Internal Target Experiments

A project to construct a ring to store beams of light ions with magnetic rigidities up to 3.6 T-m is underway at the Indiana University Cyclotron Facility. Beams from the cyclotron will fill the ring, be adjusted in energy, then cooled by electron immersion while impinging on thin targets within the ring for nuclear interaction experiments. The motivation is to explore the potential for improved resolution and reduced background of the cold storage technique. The status of the project and of selected subsystem designs will be presented.
