AWAKE Technical Board

• Issues are well followed up• Collaboration between the different work packages has strongly improved

– Still room for more involvement• Many iterative meetings in between the TB• leads to conclusions in TB• Minutes are an extremely useful tool to track actions and decisions.

– Read them carefully!• Planning is updated and available
