Experimental results are reported for stochastic cooling of the energy spread in a proton beam. The behavior of the damping rates is studied as a function of the beam phase density, number of working harmonics, and feedback circuit gain. The steady-state energy spread in the beam was determined by the noise in the electronic equipment. Coherent beam instability was found to be associated with movement of the beam in the pickup electrode. The limitations of the experimental method due to noise from the electronic equipment and collective effects in intense beams are discussed.
