  1. Baseline assumptions used by all experiments for requirements analysis Resource planning

  2. Present understanding of schedule for both 2010 and 2011 No break

  3. Prelim. schedule 2010/11/12 • 2010 + 2011 • Running from mid-Feb – end Nov • Pb-Pb in November • In principle stop after 1 fb-1 ; plan to run 2 years • (0.2 in 2010, remainder in 2011) • 2012: shutdown of accelerator (but not computing) • Guidance on availability for physics is 50% • Must agree common assumptions for #days etc. • 182 days pp and 28 days HI in each 2010,2011 • 7.9 Ms pp + 1.2 Ms HI each year assuming 50% avail • Experiments will also take data in March (pp setup) and Oct (HI setup) • Assume 30 + 14 days at 35% availability • 1.3 Ms each year • Totals: • 7.9 Ms pp, 1.2 Ms HI, 1.3 Ms “setup” in each of 2010 and 2011 • NB: For 2010 this is greater than assumptions used so far for 2010 requirements. Pledges will not change (and may decrease!) – must take care in what is said to funding agencies • Probably we should adjust the 2010 numbers to be not more than existing requirements

  4. Process now • Agree preliminary requirements for 2010, 2011,12 today • Including final agreement on assumptions and baseline • Foresee a MB in March with LHCC and RSG reps present to finalise and agree what is presented to RRB in April. • In principle should say something about 2013 to the RRB • Not clear what can be said yet • Guidance? • NB: many sites (160!!) now depend for their planning on the schedule of the accelerator. It is important that we have some clear published schedules ...
