Optical Stochastic Cooling (OSC) is a beam-cooling technique that extends the well-known stochastic cooling to optical frequencies. It may be an effective high-bandwidth cooling technology for future hadron, lepton-ion, and muon colliders. The only machine that can demonstrate OSC in the near future is the Integrable Optics Test Accelerator (IOTA) ring, which is presently being commissioned at the Fermilab.

Objectives of the OSC group are as follows:

Develop the OSC experimental concept for the IOTA ring including lattice design and vacuum chamber design
Demonstrate passive OSC at IOTA without amplification
Demonstrate active OSC at IOTA with optical amplification
Develop technologies and techniques with relevance to OSC systems in future colliders

Various resources associated with OSC will be collected in a Redmine project (here).
