Abstract

Fermilab has been working on bunched beam transverse stochastic cooling in the Tevatron since 1990. In that time much progress has been made in understanding the difficulties of making such a system work with reasonable cooling times. Problems with common mode rejection of longitudinal signals, wide band GHz signal transmission using fiber optics, and specialized optical techniques of recursive notch filters have been researched and employed. Specialized planar loop pickup and kicker arrays were developed. Signal suppression has been observed. Efforts are underway to eliminate the coherent signals that dominate the Schottky spectrum
