  Cooling of charged particle beams plays a key role in achieving peak luminosity in high-energy colliders. The presently undemonstrated technique of optical stochastic cooling (OSC)* holds promise for fast cooling of high energy protons and heavy ions. A proof-of-principle experiment with electrons is proposed at relatively modest cost using the MIT-Bates South Hall Ring, which is well suited for such a test due to its energy range, layout, and RF system, as well as its present availability. An overview of the experiment will be presented. The design of key systems for the achievement of OSC will be disucussed along with beam requirements and cooling projections.

  A proof-of-principal experiment of Optical Stochastic Cooling (OSC) at the MIT-Bates South Hall electron storage ring (SHR) has been proposed. To produce convincing cooling results, the ring will be run near 300 MeV. Beam emittances growth caused by Intrabeam scattering (IBS) is a major concern for the design of experiment. Touschek scattering imposes a dominant limit on beam lifetime. Evaluation of these effects is part of the design optimization process. Simulation analyses of cooling for a viable OSC experiment are presented.
