Abstract

Three intense bunches (two electron and one positron) are accelerated on each RF pulse in the SLC (SLAC Linear Collider) linac. Careful control of the energy and energy spectrum of each bunch is needed to provide acceptable beams at the collision point and the positron production target. The required RF amplitude, timing, and phase adjustment can be calculated and adjusted in real time to correct for changing conditions. BNS damping and energy feedback systems reduce the available reserve energy, which is limited. Observations and stability of actual beams are reviewed. Implications for a future collider are discussed.<>
