[APS Experiment Hall X-ray Operations Problem List]

The MCR lost communication with a number of Storage Ring IOCs.  Almost all
storage ring power supplies have tripped, several injector power 
supplies tripped
and all LINAC water systems have tripped.  The building 450 Operator 
notified
Operations that at the APS experienced problems, 450 experienced a power 
bump
that shut off most of their equipment.   MCR has no way to assess any 
potential
impact on beamline systems.   MCR has activiated the emergency major event
list for the accelerator.
