In order to deliver good quality beam, FACET spends a lot of machine time to daily maintenance activities and machine development. We therefore do not schedule experiments around the clock (maximum shift length is usually 12 hours).
Shifts are of flexible duration according to the science needs. Users must have a written procedure for their work that clearly indicates the time that is needed. That procedure will be agreed upon with FACET staff and then executed. If the tasks take longer than expected and the agreed upon length of the shift needs to be extended, this can usually be accommodated but will require discussion with facility staff.
