An overview of the requests from the experiments for 2011 (2012?) will be given. This will include integrated luminosity considerations, special runs and special beam conditions. Based on assumptions of achievable beam parameters, a proposal for the 2011 physics run scenario will be presented.

The first year of LHC operation was very successful regarding the peak and integrated luminosity targets, but the luminosity lifetime could probably have been better. For this reason, the luminosity evolution during physics fills is studied and correlated to single beam lifetimes and emittance growth in order to try and understand possible causes of luminosity lifetime decrease, e.g. IBS,...

The experiments do not only require high collision rates and integrated luminosity, but also an absolute normalization of the observed cross sections. This normalization can be derived from theoretical predictions or the determination of the absolute luminosity. During the 2010 proton run, the Van Der Meer scan method was used to provide a first measurement of the absolute luminosity from...
