In this week's update from the LHC, CERN reports that all replacement magnets to be installed in the LHC this year have been fitted with cryostats (the insulating vessel that allows the superconducting magnets to be chilled to close to absolute zero).
In the tunnel itself, workers are repairing the connections between the superconducting magnets and the pipeline that supplies them with liquid helium that were damaged in last September's incident; these repairs should be complete within one month.
The replacement for a problematic superconducting magnet from another sector of the LHC is in place and workers are now connecting it to its neighbors.
Technical details from CERN.
