The 248 meter Spallation Neutron Source accumulator ring is designed to operate with a beam intensity of 1.5·1014 ppp. A major concern for high intensity operation is the possibility of beam instabilities. Recently a series of experiments have been performed to systematically map out the instability parameter space. Beam instabilities have been measured versus betatron tune, ring RF voltage, lattice chromaticity, and beam intensity. The results of these studies are presented here

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.
