Welcome address

• Lyn Evans (CERN)

Room: AB Auditorium Meyrin

Linac4 Project

• Maurizio Vretenar (CERN)

Room: AB Auditorium Meyrin Overview of the Linac4 project

Operational Scenarios within the Complex

• Bettina Mikulec (CERN)

Room: AB Auditorium Meyrin - Versatility of the (present) machine (to be maintained) - Generation of “exotic” beams (some thoughts on machine activation?) - Transfer of LHC type (and other) beams to the PS

Linac4 Beam Characteristics

• Alessandra Lombardi (CERN)

Room: AB Auditorium Meyrin - Generation of energy modulation - Beam characteristics to be expected around the PSB injection (distribution region up to injection point) - Tunability, uncertainties

PS Booster beam dynamics with L4

• Christian Carli (CERN)

Room: AB Auditorium Meyrin - Longitudinal painting - Simulation of beams with strong direct space charge forces, - Limitations due to H- injection hardware, - Planned studies (investigations on feasibility of collimation)

Upgrade of distribution and injection region

• Wim Weterings (CERN)

Room: AB Auditorium Meyrin - Layout, apertures magnets of the distributor region - Layout, apertures, magnets and vacuum aspects of the injection region - Foil handling mechanism - Environment seen by the beam (BS inside/outside vacuum, shielding of cavities created ..)

Operational aspects and maintenance of the injection region

• Brennan Goddard (CERN)

Room: AB Auditorium Meyrin - Transverse painting and aperture aspects, impact of injection failures on foil - Foil exchange procedures (activation, time …) - Control of injection losses and beam dump - Specific instrumentation

Commissioning of the PSB with Linac4

• Klaus Hanke (CERN)

Room: AB Auditorium Meyrin - Commissioning strategies - Milestones - Possible difficulties and cures (use of instrumentation)

RF aspects and possible limitations

• Alfred Blas (CERN)

Room: AB Auditorium Meyrin - Instabilities with higher intensities - Beam loading problem at present with C04 cavities - Future low RF level system (communication with Linac4 for chopping)
