Collaboration with industrySchedule depends on “them”

-> first tests foreseen second half of 2011

Update: Detector Costing and Costing Tool

“mini-meetings” on CLIC detector costing :

• list of agreed unit costs• draft chapter on detector costing• critical analysis of CLIC costing tool -> feedback -> new version, will starting using it 22 February

Goal: internal cost estimate, not part of CDR Vol. Phys. & Det. (but get relative contribution of costs – cost drivers, and an analysis of sensitivity to e.g. cost for steel, etc.)

14

Update: Detector Costing and Costing Toolagreed unit costs (CLIC and ILC detectors will use same costs)

15

Update: Detector Costing and Costing Tool
