5. CLIC physics and detector study: organisation The following principles are imbedded in the structure: Acknowledgement of strong collaboration with LC physics/detector studies A means for institutes to participate (semi-)formally A means for participating institutes give direction to the project A means for participating institutes to appoint an executive body + role rotation A small executive team A steering board for the physics and detector study A strong link to the CLIC accelerator project via the CLIC Steering Committee (CSC) CSC involving CLIC accelerator and detector, ILC accelerator representation, LC detector study representation, 3-region representation A host laboratory (CERN) 5

9. The interface between “concepts” and “R&D collaborations” Can we limit the number of “steering groups” ? Can we limit the number of “review” bodies, and ensure that the review bodies are real “expert bodies” ? Role of WWS ? Which parts of the structure needs to be fully global ? Which parts of the new structure need “regional representation” ? Which parts are simply “bottom-up”, and driven by the persons/institutes who are actually participating ? Some questions about the future LC organisation 9
