LHC work this week includes cold-testing of more magnets, cryostating of more magnets (fitting the cooling systems to replacement magnets), upgrades to the magnet interconnects (one of which failed last year), and replacements of pressure nozzles throughout the ring to deal with the case of magnet quenches. More technical details here.
CERN has also posted the slides and some talks from the Chamonix LHC performance workshop that examined LHC repairs and recommended a new schedule for operations in the coming year.
