Sector 5-6, 6-7 & Point 7

Cryogenics conditions are now very stable below λ point Ice accumulation problems on current leads have been solved with the installation of dry air bags D2, Q4 & Q5 (4.5K magnets) have been powered to their nominal current (6 kA) Main arc circuits (MB & QF/QD) and correctors chains have been qualified at cold Quench protection systems and associated heaters have been validated Tests of Powering Interlock Controller are almost complete

Powering of the arc magnets is imminent … But repairs in sector 7-8 (replacement of 1055, PIMs, bus-bar on SSS 500, etc…) start early August

Need 4 weeks for warm-up, power tests have to stop prematurely

New Installation Schedule - General Features

Sector 4-5: Arc & DS ready cool-down without low- Sector 3-4: Delays with DSLC cool-down without DSLC

Get experience with HW commissioning of 2 sectors in parallel Time window for fixes after 1st HW commissioning period

Need for an extra warm-up/cool-down cycle

Sector 7-8: Repairs scheduled Aug.-Sept. power tests stop early July Sector 8-1: Repair low- (8R & 1L) before cool-down

Need to warm-up sector 7-8 before completion of first power tests programCool-down and test low- as early as possible

HW commissioning directly up to 7 TeVNeed to commission many sectors in parallelGet ready for physics by summer 2008
