E. Tsyganov et al., DECOHERENCE OF BEAM OSCILLATIONS IN THE SSC DUE TO BEAM-BEAM COLLISIONS, IEEE transactions on nuclear science, 41(5), 1994, pp. 1791-1794
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.
