Emittance and and luminosity evolution during collisions in the SSC collider

The nominal beam storage time in the SSC Collider is 24 hours. During this period, there are many co-existing effects that have impacts on the luminosity-intrabeam scattering, synchrotron radiation, pp collisions, beam-gas scattering and beam collimation. A computer program has been written which takes these effects into account simultaneously, and calculates the emittances and luminosity as a function of time. These evolution curves are compared for different operation scenarios (i.e., different initial conditions of the beam current, emittances, and beam energies.)
