Advanced Photon Source

An Office of Science National User Facility

Operations Directorate (OPS Directorate)


A group chartered by the Associate Laboratory Director for the Advanced Photon Source that includes the responsible Division Directors and other appropriate APS operations personnel.The Operations Directorate collectively coordinates operating decisions that affect the facility as a whole and establishes both long- and short-term schedules, including scheduled maintenance and facility improvement periods.

The Operations Directorate is the APS forum in which decisions regarding operations are discussed: These include, but are not limited to:

  • Safety issues related to operations
  • Operational Schedule
  • Global operating parameters within the defined and approved operational and safety envelopes, such as energy, maximum circulating beam current
  • Any unique fill patterns or operational modes to be used during a given scheduling period
  • New operational modes

The Operations Directorate's conclusions are forwarded as recommendations to the PSC ALD (APS Director) for final decision.
