Abstract:
The Metrology Light Source (MLS) is in user operation since April 2008 working at energies ranging from 105 MeV up to 630 MeV, operating currents from a single electron up to 200 mA and different values for the momentum compaction factor. In parallel to machine commissioning, an automated finite state machine has been developed. This code knows, controls and coordinates a broad manifold of machine states and meanwhile has been evolved to an automated operator acting by itself on demand of a few high level commands. Actions range from plain device I/O to complex transactions including filesystem operations and multiple device I/O. The aim is to always keep machine and control system in a well-defined state. We describe the program and report on the experience with the automated operation using this application.
