2. Alexandre.Samochkine @ cern.ch Lots of issues appear often during integration ! CLIC Two-Beam Module Systems The baseline solutions were defined for each technical system and a solution for CDR is available The module design and integration has to cope with challenging requirements from different technical systems. 2
