Time Scale l Time-Scale: - author lists, general information letter: February 2010 - Publication of changes to CLIC baseline: End March 2010 - Progressive redaction: April 2010 – late summer 2010 - First draft of CDR (vol 1&2): LC workshop at CERN in October 2010 - Almost complete draft Vol 2 for CERN SPC in December 2010 - Final CDR: Spring 2011 (vol 3).
Strategy The CDR is the document summarizing the results of the CLIC preparatory studies done at CERN together with all collaborating institutes. l Starting during the workshop 2008 details of the CDR have been communicated. Now, in the first quarter of 2010, active feedback from the CSC, the ACE, the collaboration board and the CERN management is asked for and the CDR layout and author list will be adapted. l The report will be published under the names of (300400) “supporting authors”. l It’s style and completeness will address the large audience of the high energy physics and accelerator community. l

General Comments for volume 2: l l l The CDR is based on the CLIC 3 Te. V option as baseline for the optimization of the parameters (single step construction). Implications of Construction staging starting from the lowest demanded energy as indicated by LHC results (500 Gev) up to the full 3 Te. V machine described in separate chapter. Parameter changes and optimization for this “ 500 Ge. V” machine plus additional consequences for later energy upgrades in the same chapter. Total power consumption; discussion of various scenarios from highest possible energy/luminosity to intermediate proposals in a specific chapter of volume 2 Energy scanning: For the two construction stages (500 Ge. V and 3 Te. V) a presentation of the expected performance and optimised running scenarios for an energy variation of at least a factor two again as separate chapter of volume 2. CTF 3 results: CLIC technologies as demonstrated by CTF 3 experiments will be highlighted in a separate chapter
