CLIC CDR, published/printed L. Linssen, CLIC physics and detector monthly meeting, May 14th Physics and Detectors => published ANL-HEP-TR CERN DESY KEK Report Printed copies were sent out at beginning of April. In some cases, copies took >1 month in the mail. Please let us know in case your copy did not arrive.

3 L. Linssen, CLIC physics and detector monthly meeting, May 14th 2012 Organisational matters  Post-2012 Linear Collider organisation under ICFA, in preparation At KILC12 it was announced: search committee converged on one candidate for LC director Candidate still needs to be approved by ICFA Possible announcement of LC director + 3 associate directors at ICHEP, July, Melbourne

Possible future LC organisation 4 L. Linssen, CLIC physics and detector monthly meeting, May 14th 2012 Currently, discussions are ongoing within WWS-OC and within the groups/collaborations about a model for the future physics&detector box. Some level of convergence.... about having stronger bottom-up approach than current ILC RD model

More bottom-up and self-organising than the current ILC RD structure Build upon current strong groups (ILD, SiD, CLIC p&d, CALICE, LC-TPC, FCAL..) More clear visibility/involvement of participating institutes Rotation of responsibility roles Try to limit the number of “steering groups” Try to limit the number of “review” bodies, and ensure that the review bodies are real “expert bodies” ? Questions: Role of WWS ? Which parts of the structure needs to be fully global ? Which parts of the new structure need “regional representation” ? More remarks about the future LC organisation 7 L.
