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.)

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