CRITICAL CASE: SECTOR 7-8

LSS8L

• Installation by CERN of the QRL in sector 7-8 gives the opportunity to:– Start with QRL sub-sector A and B (~600m left of point 8

(LSS8L)) in March 2005 and then, install magnets in parallel with the remaining of the QRL

– Start QRL cold testing in June 2005– Start installing magnets (LSS8L) in parallel with the

remaining of the QRL in August 2005– LSS8L cool down & power tests from October 2005 to

March 2006– Gather maximum experience on the field in 2005 with a

view to propose an optimized and reliable scenario for the other sectors

SUMMARY

• Installation dates:– LSS8L August 2005– LSS8R October 2005– LSS1L October 2005– LSS5L December 2005– LSS5R April 2006– LSS2L July 2006– LSS1R August 2006– LSS2R September 2006

• Each LSS is a particular case due to the specific configuration of the area and safety constraints such as: restriction on co-activities, on transports, on access during pressure tests, cold down and electrical tests.

• A Schedule Change Request (SCR) will be required for each LSS.
