Operational Aspects of the SLAC Main Control Center

The SLAC Main Control Center (MCC) incorporates functions that were previously handled in two separate control rooms; i.e., (1) the setup and maintenance of interlaced beams in the accelerator and (2) the delivery of the beams to separate experimental areas. The complexity of beam operation has increased with the activation of the new SPEAR facility. This experimental area uses low energy electrons and positrons which run simultaneously with a full complement of six other beams. Considering all the operational requirements, the MCC instrumentation plays a major role in determining the operation efficiency.
