MeChanICs Projecthttps://indico.cern.ch/conferenceDisplay.py?confId=106300

• FP7/People/IAPP (Industry-Academia Partnerships and Pathways) project MeChanICs, “Marie Curie linking Industry to CERN”

• start September 1st 2010, 4 year project • to enhance knowledge exchange btwn Partners on precision

manufacturing by two-way intersectoral secondments • objective: enable & enhance long term industry participation

in CLIC, Compact LInear Collider, RF structure R&D
