Review on PS Booster with Linac4

15 Jan 2009, 09:00 → 16 Jan 2009, 12:00 Europe/Zurich

AB Auditorium Meyrin (CERN)

Thursday 15 January

1 Welcome address

Speaker: Lyn Evans (CERN)

2 Linac4 Project

Overview of the Linac4 project

Speaker: Maurizio Vretenar (CERN)

Slides Linac4_PSBReview.pdf Linac4_PSBReview.ppt

3 Operational Scenarios within the Complex

- 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

Speaker: Bettina Mikulec (CERN)

Slides OPscenarios_BM.pdf OPscenarios_BM.pptx

4 Linac4 Beam Characteristics

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

Speaker: Alessandra Lombardi (CERN)

10:35 Coffee break

5 PS Booster beam dynamics with L4

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

Speaker: Christian Carli (CERN)

6 Upgrade of distribution and injection region

- 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 ..)

Speaker: Wim Weterings (CERN)

12:30 Lunch

7 Operational aspects and maintenance of the injection region

- 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

Speaker: Dr Brennan Goddard (CERN)

8 Commissioning of the PSB with Linac4

- Commissioning strategies - Milestones - Possible difficulties and cures (use of instrumentation)

Speaker: Dr Klaus Hanke (CERN)

Slides psb_review_kh_v5.pdf psb_review_kh_v5.pptx

9 RF aspects and possible limitations

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

Speaker: Alfred Blas (CERN)
