Optimisation of physics-to-physics duration -Later in 2015: decision on special runs “when and duration” (90m optics): not in the 1 st part of the year. Waiting LHCC recommendation -Pb-Pb run: one month at the end of 2015 The goal for Run 2 luminosity is 1.3 x 10 34 cm -2 s -1 and operation with 25 ns bunch spacing (2800 bunches), giving an estimated pile-up of 40 events per bunch crossing. “A maximum pileup of ~50 is considered to be acceptable for ATLAS and CMS”

The CERN neutrino programme is now well underway and active, in particular through the support for the preparation for two neutrino experiments (short- and long- baseline). A strategic collaboration has therefore been formed with FNAL for a long- term neutrino programme. The long-term strategy will allow for an important European role in future long- and short-baseline experiments at FNAL. MTP 2015 includes the construction of one detector cryostat (out of a total of four that are required) as an in-kind contribution to the facility.
