Answer

Delivered

Beam is available for the scheduled program.

 

User Off
 
Scheduled FACET user is not able to take the deliverable beam or makes an access.

 

Tuning
 
Beam conditions do not meet the requirements to carry out the scheduled program, and accelerator adjustments are being made to bring the beam to a deliverable state.

 
Config Δ’s
 
User has requested a configuration change. Time is the time to restore a deliverable beam.

 

Accel Down
 
Accelerator hardware or software problem is preventing the beam from being delivered. User hardware down is NOT Accelerator Down time.  Include specific problems causing downtime in the shift summary, with approximate time (-x.x hours). The EOIC (or their designee) is responsible for creating a CATER(s) to document all accelerator downtime for the shift.
