Accelerator Operations

The Accelerator Operations group is responsible for the operation of the accelerators of the synchrotron light source Sirius. The group has operators trained to identify, diagnose, and act on any subsystems of the machine.

In its activities, the group daily monitors thousands of parameters related to the operation of the accelerators and their subsystems. In the event of anomalies, the groups responsible for each subsystem are communicated to correct them, ensuring the full operation of the accelerators in high availability and reliability.

The group also assists users of the synchrotron light source in matters related to the unavailability of a beamline due to failure, to instabilities observed in the experiment that may be confronted with the machine parameters, and to the sharing of information on the operation of the machine.
