  1. Summary of the Design Report and Next StepsEdda Gschwendtner for theCERN AWAKE Project Team

  2. Outline • What happened since last collaboration Meeting • New Time-scale • AWAKE at CNGS • Next Steps • Outlook

  3. Since Last Collaboration Meeting • 6-8 March 2013: Collaboration Meeting @ CERN • 25 March 2013: Submit AWAKE Design Report to CERN management and SPS Committee • Use the CNGS facility for AWAKE (not West Area). • 9-10 April 2013: SPSC Meeting • Very positive feedback • List of questions – Answers sent back to referees • Mid May 2013: several discussion with CERN management and finance group • Needed resources for AWAKE@CERN are fully included in the CERN Medium-Term Plan • MTP (period 2014-2018) must be approved by the CERN council. • AWAKE program has to be stretched.

  4. Since Last Collaboration Meeting • 17-21 June 2013: Council week • 17/18 June: Scientific Policy Committee  recommendation to Council • 19 June: Finance Committee  recommendation to Council • 20/21 June 2013: CERN Council  Approval In case it the MTP is not approved: • 16-20 September 2013: Next CERN Council meeting • 25-26 June 2013: SPSC meeting • Recommendation of scientific case. • As soon as approved • Secure the manpower in the different departments and groups.

  5. Time-Scale as written in the Design Report Time-scale for AWAKE in Design Report Components preparation Installation data taking Commissioning Civil engineering & Installation Studies, design, Components preparation Installation Fabrication Studies, design Commissioning Needed CERN resources: Costs: 8.5 CHF Person-Years: 34.2 PY

  6. Time-Scale as in the CERN Medium-Term Plan Study, Design, Component preparation Installation data taking Commissioning Studies, design, Component preparation Civil Engineering, modifications and installation Time-scale for AWAKE in the MTP data taking Installation Fabrication Studies, design Commissioning Needed CERN resources: Costs: 8.5 CHF Person-Years: 34.2 PY  Budget and manpower profile for 5 years

  7. SPS CNGS West Area CERN

  8. Comparison CNGS – AWAKE • AWAKE: • ~Factor 100 less protons/extraction • ~Factor 1000 less protons/year • CNGS is a running facility(since 2006) at the desired beam parameters. • Proton beam and secondary beam-line fully equipped and running • All services (CV, EL,…) running • Underground facility • Adequate site for AWAKE

  9. AWAKE at CNGS AWAKE experiment ~1100m AWAKE beam dump

  10. AWAKE at CNGS 750m proton beam line Access gallery to the experimental area CNGS target area (stays untouched) Electron source area Future AWAKE experimental area (will be emptied)

  11. Layout of the AWAKE Experiment Introduction – AWAKE at CERN – Layout of AWAKE – Summary

  12. Layout of the AWAKE Experiment Introduction – AWAKE at CERN – Layout of AWAKE – Summary • Plasma cell: • baseline is vapour cell. • housed in downstream end of the proton beam-line. • Area can be modified to house a shorter vapor cell and a helicon and/or discharge source.

  13. Layout of the AWAKE Experiment Introduction – AWAKE at CERN – Layout of AWAKE – Summary • Beam Diagnostics • Beam diagnostics for outgoing protons. • Electron spectrometer magnet and diagnostics.

  14. Layout of the AWAKE Experiment Introduction – AWAKE at CERN – Layout of AWAKE – Summary • Laser system: • CNGS storage gallery modified • Dust-free • Over-pressurized • Temperature regulated.

  15. Layout of the AWAKE Experiment Introduction – AWAKE at CERN – Layout of AWAKE – Summary • Electron source and klystron • Housed in the ventilation chamber. • Low radiation area, free of electromagnetic interference. • Electron beam through new liaison tunnel to connect electron source and proton tunnel.

  16. Layout of the AWAKE Experiment Introduction – AWAKE at CERN – Layout of AWAKE – Summary • AWAKE area is separated from the CNGS target area • 80cm thick concrete chicane shielding. • Dust-proof separation doors. • Separate ventilation system.

  17. Electron Beam Line See MalikaMeddahi’sTalk

  18. See Alexey Petrenko’sTalk

  19. See Eduard Feldbaumer’s Talk

  20. Next Steps • Prepare the CNGS facility for AWAKE • Install an evaporator for the CNGS water system • Decay tunnel safety • Detailed Radiation protection calculations in the area. • Electron beam line (dedicated studies for magnets around plasma, space charge effects). • Close collaboration with institutes • Electron beam injection studies  to be benchmarked with OSIRIS?! • p, e, laser – synchronization between Laser and SPS RF

  21. Outlook • AWAKE@CERN moves from study phase to project phase. • Detailed project-structure with work-packages, etc.. • Design, construction, installation and commissioning. • Aim • First proton beam to plasma-cell in 2016. • Electron beam in 2017/2018.
