LHC "bird-bread" strike

On Tuesday 3 November, a bird carrying a baguette bread caused a short
circuit in an electrical outdoor installation that serves sectors 7-8 and
8-1 of the LHC. The knock-on effects included an interruption to the
operation of the LHC cryogenics system. The bird escaped unharmed but
lost its bread.

The standard failsafe systems came into operation and after the cause
was identified, re-cooling of the machine began and the sectors were
back at operating temperature last night. The incident was similar in
effect to a standard power cut, for which the machine protection systems
are very well prepared.
