Expected beams in the LHC at the end of September, collisions late October. This is a 6-week delay compared to the previous schedule...
The cause of this delay is due to several factors such as implementation of a new enhanced protection system for the busbar and magnet splices, installation of new pressure relief valves to reduce the collateral damage in case of a repeat incident, application of more stringent safety constraints, and scheduling constraints associated with helium transfer and storage.
In Chamonix there was consensus among all the technical specialists that the new schedule is tight but realistic.
The new pressure relief valves will be installed in the 4 warmed-up sectors this year, and they will be installed in the cold sectors in 2010.
A bientôt!
