The Colliding Beams Sequencer

A description is given of the Colliding Beam Sequencer (CBS), a computer program used to operate the p-p collider by synchronizing the applications programs and simulating the activities of the accelerator operators during filling and storage. The Sequencer acts as a metaprogram, running otherwise stand-alone applications programs to perform the set-up, beam transfers, acceleration, low beta turn on, and diagnostics for the transfers and storage. The Sequencer and its operational performance are discussed along with its special features, which include a periodic scheduler and command logger.<>
