Abstract :
Beam orbits in the SLC are monitored in real time, and the data are stored for future trend and correlation analysis. Software has been developed that permits both real-time and offline continuous monitoring and analysis of the beam orbits in all parts of the machine. A background process acquires beam position monitor (BPM) and toroid data on a periodic basis and saves the general quantities such as orbit RMS and beam intensity in addition to the individual readings. Some of this data is archived by the SLC history buffer facility and the rest is saved in files for later analysis. This has permitted the tracing of interaction point instabilities to specific devices as far away as the damping rings. In addition, the data are displayed for the operators both in summary and in full form. The different displays can be configured from the control consoles.<>
