The call for proposals for Cycle 29 (January to June 2019) has been cancelled. All projects that have had shifts cancelled due to this outage will have the same number of shifts scheduled during our next cycle.

Update: December 19, 2018: 

Dear Users,

I am pleased to inform you that our repairs to the electron source are on track for the start-up of operations.

We suffered a minor setback last week, as a specialized transformer needed repairs; however, we had built-in contingency for such an event and are still on schedule to deliver user beam by late January 2019. We will communicate once we have successfully brought all machine systems back into operation in the New Year.

As previously communicated, all projects that have had shifts cancelled due to this outage will have the same number of shifts scheduled during our next operating cycle. We have tentatively scheduled January and February beamtime, and the remainder of the shift allocations for the cycle will be finalized and scheduled in early 2019.

The draft schedule for 2019 is available here:  

The development (D) shifts in January are reserved to bring back our accelerator suite (linac, booster, and storage ring) to full operations, which has been down for six months. The similarly large number of normal special (NS) shifts are intended for bringing back our beamlines, which likewise have been idle for 6 months. In addition, the two-month outage in March and April (M shifts) is intended to replace the booster radio-frequency power supply, which has been identified as another high-risk single point of failure.

If you have any questions or concerns about the beamtime rescheduling process, please contact the User Services Office at or 1-306-657-3700.

Lastly, on behalf of our entire staff, thank you for your patience and loyalty throughout this difficult period.

Happy holidays, and we look forward to seeing you in the New Year.


Mark Boland

Machine Director
