Outline What happened since last collaboration Meeting New Time-scale AWAKE at CNGS Next Steps Outlook Edda Gschwendtner, CERN2

Since Last Collaboration Meeting 6-8 March 2013: Collaboration CERN 25 March 2013: Submit AWAKE Design Report to CERN management and SPS Committee – Use the CNGS facility for AWAKE (not West Area) 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 are fully included in the CERN Medium-Term Plan – MTP (period ) must be approved by the CERN council. – AWAKE program has to be stretched. Edda Gschwendtner, CERN3

Since Last Collaboration Meeting 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: – September 2013: Next CERN Council meeting June 2013: SPSC meeting – Recommendation of scientific case. As soon as approved – Secure the manpower in the different departments and groups. Edda Gschwendtner, CERN4

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 Edda Gschwendtner, CERN20

Outlook 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 Electron beam in 2017/2018. Edda Gschwendtner, CERN21
