On-Line Model Driven Control of the SLC Electron Damping Ring

摘要

Model driven procedures have been used for control of the linac, beam transport lines and storage rings at SLAC. These procedures, based upon computer models of the machine lattice, are used for on-line calculation of the strengths of beam line components which yield desired lattice parameter values. They are also used for routine operation of the machine and for diagnosing and correcting errors of various types, as well as for aiding physicists in the acquisition and presentation of data. Successful operational experience in the use of such procedures at the PEP and SPEAR storage rings has led to the decision that this method of operation will be used for control of all of the SLC subsystems: two-mile Linac, Arcs, Final Focus Region, Positron Return Line and the Damping Rings and their associated injection/extraction beam transport lines. The purpose of this paper is to describe the development of the on-line model driven control procedures and their implementation in the SLC computer control system. (ERA citation 10:034422)
