Scenarios and Technological Challenges for a LHC Luminosity Upgrade: Introduction to the LHC Upgrade Program and Summary of Physics Motivations

After a general introduction to the motivations for a LHC upgrade, the lectures will discuss the beam dynamics and technological challenges of the increase of the LHC luminosity, and the possible scenarios. Items such as a stronger final focus with larger aperture magnets, crab cavities, electron cloud issues, beam-beam interaction, machine protection and collimation will be discussed.
