Abstract

The design of the pickup and kicker electrodes for the 4-8 GHz stochastic cooling system being designed for installation into the Pbar Accumulator Core at Fermilab is discussed. The electrodes are one-quarter-wavelength-long microstrip lines. Transit time effects due to the finite spatial extent of the coupling region between the electrodes and the particle beam can substantially decrease the bandwidth of the electrode. These effects are relieved by reducing the extent of the coupling region and electrode size. The desired aperture is achieved by the combination and the proper location of two electrodes
