Dynamic aperture of the chromatically corrected Collider lattice
A scheme for correcting the second order chromatic effects generated by the Interaction Regions (IRS) has been designed for the SSC Collider ring, where four families of sextupoles are located in the arc sectors next to the East Cluster. The effect of these sextupoles on the dynamic and momentum aperture of the machine has been evaluated with a simulation model in which alignment, field errors and operational corrections are realistically represented. Several optics configurations with different values of {beta} at the Interaction Points (IPs) have been studied for different sets of field error specifications in the IR quadrupoles. The local chromaticity correction system improves the momentum aperture of the Collider for every configuration studied with no relevant loss of dynamic aperture on momentum, when the effect of errors are taken into consideration.
