Are there more like this?

• We have seen 2 of 36– One bad– One good

• Can they be inspected?– Fire foam makes it difficult for a

visual inspection of the pvc coupler• Trying to look for other indicators

– Turn on order– Ground current

• What we learned– We understand the problem, process

and how to recover more quickly

Complex Status– Accelerators

• Recovering from MI ground fault• Monitoring systems during Kautz Road SubStation

test• Investigating issues, understanding, planning• No plans to switch back to Master SubStation

– Would like to see slip stacking – Maybe in February 2015

– NuMI• Beam to experiments

– Switchyard• Beam to experiments

– SeaQuest• Beam to experiments

– Meson Test• Intermittent users

– Meson Center• No users

– BNB• Horn replacement
