Tevatron Operational Status and Possible Lessons for the LHC
This talk will provide an overview of the
Tevatron Run II luminosity progress and V.A. Lebedev (Fermilab)
plans, including SC magnet measurements
and modeling of field errors in view of the LHC operation, electron cooling progress and results, slip-stacking and
optimized use of the injectors for antiproton production, and improvements in the antiproton source.
RHIC Operational Status and Upgrade Plans
Since 2000 RHIC has collided, at 8 energies,
4 combinations of ion species, ranging from W. Fischer (BNL)
gold ions to polarized protons, and including
the collisions of deuterons with gold ions. During that time the heavy ion luminosity increased by 2 orders of
magnitude, and the proton polarization in store reached 46% on average. Planned upgrades include the evolution
to the Enhanced Design parameters by 2008, the construction of an Electron Beam Ion Source (EBIS) by 2009, the
installation of electron cooling for RHIC II, and the implementation of the electron-ion collider eRHIC. We review the
expected operational performance with these upgrades.
LHC Luminosity and Energy Upgrades
LHC upgrade studies are ongoing as part of
the EU CARE-HHH network and in the US- W. Scandale (CERN)
LARP collaboration. The aim is a ten-fold
increase of the LHC luminosity by about 2014 and a possible upgrade of the injector complex to inject at 1 TeV
and, at a later stage, to raise the collider energy. This talk will provide an overview of the beam dynamics and
technological challenges associated with the LHC upgrade, including magnet R&D plans, electron cloud and beambeam
limitations, preferred scenarios to maximize the integrated luminosity, and machine experiments on beambeam
compensation or crystal collimation.
