Stochastic cooling is a broadband microwave feedback system used in particle accelerators to reduce beam size growth. Because stochastic cooling is a random process, the performance of the system is directly proportional to the bandwidth of the system. Electrodes that sense and correct the position of particles in the beam must accommodate octave bandwidths in the range from 1 to 16 GHz. This article will outline the theory, design, and measurements of planar electrodes that achieve these wide bandwidths.
