Description
The LHC physics programme with heavy ions (lead-lead) collisions at
a luminosity of 1027 cm-2s-1 can be achieved by upgrading the ion
injector chain: Linac3-LEIR-PS-SPS. The conversion of the Low Energy
Antiproton Ring (LEAR) to a Low Energy Ion Ring (LEIR) has already
started. The conversion includes new magnets and power converters, a
high-current electron cooling system, broad-band rf cavities,
upgraded beam diagnostics and vacuum equipment to achieve 10-12
mbar. The start-up of the beam commissioning is planned for summer
2005. The impact on the proton LHC start-up of the major hardware
changes in Linac3 (installation of the new ECR source and the
test of the energy ramping cavity), LEIR, PS (new injection system,
rf gymnastics),the stripping insertion between PS and SPS and their
commissioning is discussed The milestones, schedule and an
estimation of the lead beam brilliance and intensity in LHC are
tentatively shown.
