  1. CERN AWAKE Project Status

  2. Outline Introduction Project organization West Area and CNGS AWAKE facility studies Required input from the Collaboration Summary

  3. Introduction • June 2012: • Official CERN AWAKE project (including project-budget) with mandate sent by S. Myers to CERN departments. •  organize CERN efforts to produce parts of CDR under CERN responsibility • CDR includes detailed budget, CERN manpower and schedule plans for design, construction, installation and commissioning. • Deliverables: • End 2012:  preliminary report summarizing the ongoing study to the A&T sector Management • Q1 2013:  Conceptual Design Report to the A&T sector Management and the SPSC. • CERN AWAKE project: •  Work-package leaders and contents have been defined •  Experts from technical groups defined and discussions/iteration in WPs are ongoing

  4. Mandate of CERN AWAKE Project • Identify the best site for installation of the facility on the SPS by carrying out a study covering: • The design of the proton beam-line from the SPS to the entry point of the plasma cell, to meet the required parameters. • The design of the downstream beam-line from the plasma cell to the beam dump. • The design the common beam-line for the proton, electron and laser light beam at the entry into the plasma cell. Specification of the parameters for these incoming beams. • The design of the experimental area (envelope) considering layout optimization of all components in the area. • The study of access possibilities and assess radiation and safety aspects. • The study of the general infrastructures (Civil Engineering, Access, CV, EL, transport, handling, control). • The physics program that could be carried out on each site. • The comparison of the cost and of the schedule of the alternative sites. • Based on the study, recommend a site for the facility and deliver the chapters, covering the beam line, the experimental area and all interfaces and services at CERN, in the conceptual design report (CDR) of the AWAKE CERN facility. The CDR should include the points mentioned in the section above plus the following information: • Specification of the baseline beam parameters to be used for the design. • Predictions of measurable quantities in the diagnostic instrumentation. • Specification of diagnostic instrumentation in the experimental area. • Design and interface with the electron beam up to the plasma cell. • Study all interfaces between the different systems (plasma cell, electron beam, proton beam, laser…) • Evaluation of time scale and costs of all items at a level needed for the CDR. • Evaluate dismantling feasibility and cost.

  7. Proton Beam Specifications

  8. Beam Specifications Electron beam specifications Laser: 30fs, 800nm, ~TW. R & D facility:  frequent access to plasma cell, laser, etc… needed.

  9. Experimental Layout Laser e- spectrometer RF gun e- Proton beam dump 10m Plasma-cell ~3m Laser dump SPS protons OTR Streak camera CTR EO diagnostic 10m 15m? 20m 10m?

  10. SPS CNGS West Area

  11. Facility Site I: West Area Proposed in LOI, 2011 TT5 183 TT4 AWAKE TT61 Beam from TCC6 - SPS Until 2004: West Area used as experimental beam facility. West Area today: Proton beam line TT61: ~empty TT4 and TT5: storage area for (radioactive) magnets  Needed during LS1!

  12. Facility Site II: CNGS

  13. TBID 2.7m 43.4m 100m 5m 1095m 18m 5m 67m CNGS Today • Since 2008: running facility: muon neutrino production in order to measure • appearance of tau-neutrinos in Gran Sasso experiments. • Proton beam and secondary beam-line fully equipped and running • All services (CV, EL,…) running p + C (interactions) p+,K+ (decay in flight) m+ + nm  Approved for 22.5·1019 protons on target AWAKE • Expect ~10 ntevents in OPERA  today: 17.3·1019pot, by end of 2012: ~18.3·1019 pot

  14. List of issues we currently study for facility evaluation: • Radiation protection • Civil engineering • Proton beam-line • Layout and integration • Dump • Electricity • Access • Cooling & Ventilation • Storage & handling • Safety • …

  15. Radiation Protection Studies and Consequences Helmut Vincke’s talk West Area: • Make sure that radiation levels from muons are below RP criteria. • Consequences: • Bend p- beam down-wards, limited number of beam shots, different energy? West hall ChiaraBracco’s talk CERN fence Plasma Cell • Civil engineering  build a beam-trench Dump John Osborne’s talk • CNGS (underground area): • Accessibility • CNGS target, horns removal 2°

  16. Layout, Integration Studies Ans Pardons’ talk • West Area: • Consider civil engineering • Consider footprint of AWAKE experiment (120 m) Access Gallery • CNGS: • As long as no decision on CNGS continuation taken: • Keep CNGS facility in shape • Install AWAKE experiment temporarily • Many more details from collaboration on footprint required! Storage gallery TSG41 Target chamber Proton beam line TT41 Junction chamber Target Horn

  17. EL Infrastructure DavideBozzini, EN-EL • Technical galleries! • 18kV & 66kV power lines: backbone of the CERN grid • Installation until end 2012 TT5 TT4 66 kV power line 18kV CNGS: • EL infrastructure exists, but must be modified  EL infrastructure can only be done once all electrical consumptions are estimated by the clients (PC, CV, general services) and the type of network is specified West Area: • Primary substation is close (200m) • Existing infrastructure old • A lot must be refurbished, renewed…

  18. Cooling & Ventilation Michele Battistin, EN-CV • West Area: • Pumping system, cooling towers, piping connections • need refurbishment, redoing, some of them could maybe be used • Separate ventilation systems for proton beam-line, experimental area and dump • CNGS: • Ventilation system exists • But needs some modifications  CVinfrastructure can only be done once all cooling and ventilation needs are estimated by the clients (PC, CV, general services).

  19. Access System RuiNunes, GS-ASE • West Area: • new access system of ‘primary area type’ (higher level of risk exposure and radiation classfication) • Turnstile and material access door needed, passive beam stopper, • Interlock system shared with HiRadMat and LHC (to be modified) • De-coupled from nTOF area Existing/new beam line TT61 Access Point Access gallery for nTOF/TT61 nTOF Access Point Shielding/Civil Eng. Must leave path for access to nTOF • CNGS: • Existing access could be moved down the tunnel • Modifications needed •  Physical layout of the area very important for more design details!

  20. West Area vs CNGS – Incomplete! Further Detailed Studies Needed!!

  21. Time-Scale West Area: Beam not before 2017:  New magnets, build new storage area, new service installations… CNGS: Beam 2015: Only when reusing proton beam-line magnets and no dismantling of CNGS target, horns.

  22. Summary • CERN project structure well defined. • Studies ongoing for West Area and CNGS. • Many issues have already been defined. • Many iterations with technical groups needed. • Need input from Collaboration to advance!

  23. Necessary input from Collaboration By end October 2012!! Detailed layout of ALL equipment (+ auxiliaries) Electrical consumption Cooling & ventilation needs Radiation hardness of equipment Safety information: laser, klystron, gas, … Control needs (control room, computers, ….) Access needs

  24. Necessary input from Collaboration By end October 2012!! Electron beam injection  interface with p-beam? Quadrupoles downstream the plasma cell Specification of energy Minimum number of shots
