Lepton-Proton Scattering Experiments
Status 2009
done
planned
LHeC is a unique DIS machine project at the high energy frontier
Scale of new physics is TeV, Unitarity violation in ep and eA, Electroweak physics, Single top, Higgs.. This machine also does large x, low Q2 , photoproduction, amplitudes…, NOT polarised-polarised lN

Editorial ProcessECFA 26.11.2010
Draft 0.9 [about 500 pages]
Editorial Board: Oliver Bruening, John Dainton, Stefano Forte, Max Klein, Paul Laycock, Wesley Smith
31.1. – Draft 1.0 to Referees
31.3. – Feedback from Referees (consultation with authors+CERN) … Update of CDR*) including plan for R+D, installation, schedule [Oliver today]
… formal response from referees
-- Print Europe’s Strategy Debate
LHeC CDR Referees invited by CERN Directors *) this CDR presents a design concept and its motivation

ConclusionKeeping an LHeC option open for the LHC requires: launch of R&D and design activities for key components (magnets, RF) needs to start very soon planning the installation of the ring-ring option requires careful synchronization with LHC operation schedule (assume minimum of two long shut downs for installation) Civil engineering must start before 2018
163rd CERN-ECFA-NuPECC workshop on the LHeC , 12-13 November 2010
Requirements: The above work can not be done with the current arrangement and requires a focused team and sufficient resources
Conclusion: Decision on LHeC option should be taken by 2012

Ist der eine kundig des Meeres

Und in der Erinnerung
Das Meer wird blau sein
