  1. 10. Expectations from Review
    Steve Myers (CERN)
    14/06/2011, 14:00
  2. 5. Collimation project upgrade plan and questions
    Dr Ralph Assmann (CERN)
    14/06/2011, 14:05
    Outline of collimation upgrade plan. What is planned when and why? What are the questions arising for this upgrade plan?

  3. 7. Dispersion-suppressor upgrade IR3
    Vittorio Parma (CERN)
    14/06/2011, 14:35
    Foreseen work in IR3 for first long shutdown? Short description. Planning aspects.

  4. 9. Proton beam performance with and without IR3 upgrade
    Adriana Rossi (CERN)
    14/06/2011, 14:55
    What is lost when not doing the IR3 upgrade? Gain from DS collimators. Performance reach without (see also morning presentation) and with dispersion suppressor collimators for protons.

  5. 13. Ion beam performance with and without IR3 upgrade
    Giulia Bellodi (CERN)
    14/06/2011, 15:15
    Ion performance reach without and with dispersion-suppressor collimators in IR3. Other ion limitations (IR2, ...). Possible impact from delay of IR3 work on IR2 upgrade of dispersion suppressors.

  6. 14. Energy deposition with and without IR3 upgrade
    Dr Vittorio Boccone (CERN)
    14/06/2011, 15:50
    Predicted energy deposition with and without IR3 dispersion suppressor collimators. Gain from collimators. Performance reach from comparing peak heat deposition with quench limit. Comparison with MD results.

  7. 15. Impedance without IR3 upgrade
    Nicolas Mounet (Ecole Polytechnique Federale de Lausanne (EPFL)-Unknown-Unknown)
    14/06/2011, 16:10
    Impedance from tight collimation settings as achieved in MD. Will the beams be stable with impedance, taking into account stabilization from transverse damper and octupoles?

  8. 8. Outcome Risk Review for IR3 Work
    Philippe Lebrun (CERN)
    14/06/2011, 16:30
    Conclusions from May review in EN/TE departments. Technical feasibility? Major risks? Any show-stoppers identified?

  9. 16. Activation issues in dispersion suppressors
    Stefan Roesler (CERN)
    14/06/2011, 16:55
    Expected activation levels. Are additional limits expected on work in dispersion suppressors during later shutdowns?

  10. 17. Radiation damage in dispersion-suppressor magnets
    Dr Davide Tommasini (CERN)
    14/06/2011, 17:15
    Can the radiation dose on unprotected magnets in the dispersion suppressors be accepted? What is the radiation hardness and can unacceptable damage to magnets be excluded, for protons and ions?
