Cooling of hadron beams is often the only technique by which accelerator facilities around the world achieve the necessary beam brightness necessary for their physics research. In this paper, we will give an overview of the latest developments in hadron beam cooling, for which high energy electron cooling at Fermilab’s Recycler ring and bunched beam stochastic cooling at Brookhaven National Laboratory’s RHIC facility represent two recent major accomplishments. Novel ideas in the field will also be introduced.

An analog wideband feedback system for damping e-p instabilities has been demonstrated at the PSR at Lansce. A mixed signal system is being developed and deployed at SNS. The status and expected performance of the of the system is discussed.
