Abstract :
The energy of the Stanford Linear Collider is stabilized by using a hardware-based feed-forward system. The three bunches are stored and cooled in the damping rings, and coaccelerated in a single machine cycle. Prior to extraction of the stored bunches, the energy gain of the accelerator is set by rephasing of klystrons to correct for anticipated beam loading effects. A discussion is presented of the hardware associated with determining the intensities and the appropriate energy corrections to compensate for variations in energy due to beam loading effects. Machine tuning procedures, diagnostics, and operational experience are discussed.<>
