Description
Several years will be required to reach the LHC nominal performances. During the
year 1 and 2, the LHC beam current will be limited, therefore the nominal
performances of the vacuum system are not required. In this context, the vacuum
performances for year 1 and 2 will be analysed. Particularly, the bake-out of the
Long Straight Sections could be questioned. The implications of an unbaked vacuum
system onto the resources, the installation schedule, the beam life time, the
quench
level, the dissipated power into the cold masses and the radiation dose onto the
machine elements will be discussed.
