[Xrayops] Scheduled refill of the Storagering Canceled
APS Experiment Hall X-ray Operations Problem List

Wed Dec 17 17:46:44 CST 2008
The 19:45 refill of the storage ring tonight and, most likely, the 07:45
refill tomorrow will be canceled due to problem with the motorized fused
disconnect which provides power to the Booster RF system. This piece of
equipment is located outside and, due to the weather and lack of light,
no work can be performed on this system until tomorrow morning. We
should know between 10:00 and 12:00 tomorrow whether this equipment can
be repaired by 16:00. If it cannot be, we will schedule a storage ring
beam dump and switch to a back-up RF system. This switch will result in
no stored beam for approximately three hours.
If stored beam is lost before the equipment can be repaired, personnel
will be contacted to come in immediately and do the switch to the
back-up RF system at that time. The downtime in this case would be
expected to be in the 3-1/2 to 4 hour range.
We will send out an update at around 10:00 tomorrow, or earlier if we
have any information regarding the repair.
Storage Ring, Chief of Operations
