Update re. Unexpected 520 MeV cyclotron downtime

[Lisa Lambert]

Colleagues -
During the ramp up after the power outage, the Linde cryoplant for TRIUMF's 520 MeV cyclotron experienced significant technical issues which have to be addressed before being able to start the cyclotron up again. Teams are currently warming the system up to prepare for an assessment of the situation, which will be followed by repairs to safely and speedily return the system to regular operations so that we can be delivering beam.
At present, the estimate is a three-day turnaround for repairs and to bring the 520 MeV cyclotron back online. As such, we do not expect to resume beam delivery before this Thursday, October 25.
We will provide updates when repair work is further along and when beam delivery can be confirmed.
We're sorry to those impacted and inconvenienced by this unexpected cyclotron downtime, particularly those losing experimental beam time. We're grateful for your understanding as we work diligently to resolve the matter.
Sent on behalf of
Reiner Kruecken
TRIUMF Deputy Director, Research
