Simulation of longitudinal phase space in the SLC

Upon leaving the damping ring, the SLC (SLAC Linear Collider) beam passes through the ring-to-linac transfer line (RTL), the linac, and the arcs on its way to the collision point. In an earlier paper by K. Bane and R. Ruth (1989), calculations of the longitudinal distributions of the lengthened damping ring beam were presented, calculations that agreed remarkably well with measurements. The author presently propagates the damping ring distributions through the rest of the machine. Among the effects that are included in the calculations are the curvature of the compressor RF and the limited energy aperture in the RTL, the wakefields in the linac, and the momentum compaction in the arcs.<>
