Abstract
Computer simulations were made to study the decoherence of beam oscill ations in the SSC collider due to the tune shift generated by the head -on beam-beam interaction. Our simulation results on the average tune shift and the rms tune spread were compared with previous theoretical estimates and excellent agreement was found. Our simulations also conf irmed the expectation that the decoherence time increases with decreas ing tune spread in the beam. A simple procedure was presented to quant ify the decoherence time from the simulated growth of the beam emittan ce relative to the beam centroid.
