Abstract :
A system for controlling vertical single bunch instability is described. The vertical position of each of the 1,113 bunches in the Fermilab Main Ring is digitized and stored in a memory. After an interval determined by counting RF cycles, the memory is read. The delayed position signal is sent to a distributed amplifier. A transmission line serves as a beam deflector.
