Michael, There's some confusion about the pileup numbers for the high energy LHC scenarios. The current baseline has 50 ns bunch spacing because of concerns about electron cloud and the energy, but they still seem to be quoting the pileup numbers for the 25 ns case. I'll check on this. In any event, the pileup for the 100 TeV case is to low. It should be the same or a bit (~10%) higher than the 30 TeV case, whatever the number is. I'll look into this and get back to you quickly. -Eric On Mar 7, 2013, at 12:40 AM, Peskin, Michael E. wrote: > Dear Colleagues, > > Finally, everyone concerned has gotten back to me, and we are ready to post the > "Official Energy Frontier Facilities List".
