Steve Myers has pointed out that the overlap knockout resonances are potentially harmful to the stability of two beams with different revolution periods. In this note we present a follow-up study of this effect for the SSC. One possible reason for the two beams to have different revolution periods is operation at different energies, especially at injection. The velocity difference then translates into a difference in revolution periods. Another case is when the two beams have different horizontal orbit distortions (even when they have the same energy), which in turn makes the circumferences different. A third possible cause is when there is a circumference difference due to survey errors during construction. These effects can in principle be compensated by adjusting the rf frequencies, but this is done at the cost of aperture and ought to be avoided if possible.
