Status of the Nominal Proton Beam for LHC in the PS

The RF systems which are necessary for the generation of the nominal proton beam for the LHC in the PS Complex have been installed in the PSB and in the PS during the shutdown 97-98. This has permitted the complete set of longitudinal operations required by this beam to be tested and adjusted. The hardware status and the results achieved so far are summarised in this paper. The subjects of study, the foreseen improvements and the expected beam characteristics in 1999 are also described.
