Description
Pre-requisites for switching from p-p to Pb-Pb operation of the LHC
(optics,controls, vacuum, instrumentation, etc.). Plan for
commissioning the main rings with lead ions. Differences from p-p
operation (RF, vacuum requirements, beam instrumentation, separation
and optics in collision). Evolution of beam intensity,emittance and
luminosity; effect of vacuum, the number of experiments illuminated,
length of fills and any reduction in beam energy. Elucidation of
performance limits (quenches from Pb81+, collimation) in the "Early
Ion Scheme" and evolution to nominal luminosity.
