A review will be given of vacuum effects for the LHC upgrade following the decision to coat all room temperature sections with getter films. Recent measurements in the SPS of the electron cloud and of beam induced multipacting (BIM) will be interpreted in the light of secondary ionisation of the residual gas by the electron cloud. An estimate of the space charge of the ion cloud will be given. The implication of the resulting additional ion bombardment of the vacuum chamber on the conventional vacuum stability criterion, specifying an upper limit for the product of ion induced desorption yield and beam current (hI)_crit will be given.
