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.

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.

Comparison CNGS – AWAKE
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
Parameters CNGS AWAKEProton beam energy from SPS 400 GeV/c 400 GeV/c
Cycle repetition rate 0.17 Hz 0.03 Hz
Number of extractions/cycle 2 1
Protons per cycle 2x2.4E13 3E11
Proton pulse length 10.5 ms 1.5 ns
Beam power (max.) 510 kW 640 W
Beam size at target (s) 0.5mm 0.2mm
Protons/year 4.5E19 4.5E16
AWAKE: ~Factor 100 less protons/extraction ~Factor 1000 less protons/year

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.

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.

• AWAKE area is separated from the CNGS target area• 80cm thick concrete chicane
shielding.• Dust-proof separation doors. • Separate ventilation system.

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

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.
