3. Flex assembly procedure Genova flex StepsTaskPlaceResponsible 11 Glue flex on stave A calibrated thickness of glue is applied on the flex, flex position on the stave is accurate Polymer lab @ CERN Polymer team + Francois-Xavier Nuiry 122 Final electrical tests: at CERN and UniGe Polymer lab @ CERN +UniGe Claudia (CERN) + Didier Ferrere (UniGe) 13Load modules on the stave UNIGE Didier Ferrere 14 Final electrical test The Stave + flex system is tested and validated, then we remove the non permanent intermediate flex UNIGE Didier Ferrere
