Beta-Beam Task Progress Milestones Status of ongoing work Open issues Conclusion EURISOL – Coordination Board Meeting
Milestones Last milestone (month #9) was to fix the parameters along the accelerator chain • In-/ejection energies of the machines, cycling times, ion intensities along the chain ... • Allows the sub-tasks now to progress on detailed design and investigate major technical challenges No milestones defined for the period winter05/spring06 Next milestones are upcoming at reporting month 18, which are • M2.2 RCS first order optics design • M3.2 PS and SPS: Identification of limits • M4.2 Decay ring first order optics design Present activities to achieve the milestones above are ... EURISOL – Coordination Board Meeting
Subtask 2: Low Energy Ring(s) RCS (Orsay) • update on first order design • Ejection energy raised to 3.5 GeV proton equivalent • Simulation of multi turn efficiency: performance better than originally estimated LE accumulation ring (non-baseline option) (SU-MSL) • Simulations of electron cooling EURISOL – Coordination Board Meeting
Subtask 3: PS and SPS • Analysis of dynamic vacuum effects (GSI) • Pressure in PS reaches very high levels • Currently investigation to improve unacceptable situation EURISOL – Coordination Board Meeting
Optical functions (m) s (m) Subtask 4: Decay ring Major issues: • Collimation • Insert dispersion section in straight section • Collimate 1MJ per beta-beam cycle! • High peak current (200 Amps) and RF aspects in the decay ring Collaboration between CERN and Saclay EURISOL – Coordination Board Meeting
Conclusions Work is progressing according to plan of the Beta-beam task. No deviation from planning • Beta-beam task now concentrates on • All machines: address technical design issues (RF, Vacuum requirements, magnet design etc.) • Improvements for vacuum situation in PS • Collimation in the decay ring (Optics design, simulation of energy deposition ...) • 18Ne shortfall • Feedback on expectations for ion production and beam preparation? • For the further progress of sub-task 2 (RCS, LE accumulation) a first order design of the post accelerator should be addressed.
