WHAT NEXT? Linac (150 MeV -> 1 GeV) design under WP9 responsibility? 1 GeV FEL parameter list identified, good starting point Plasma scaling laws (linear – non linear regimes) to define plasma target, driver characteristics and operational regime Input from WP5 about parameter 2) Next WP9 meeting in January (week of 22/1/2017) in Hamburg: -drive beam parameters, -propose joint experimental activities, -code discussion and sharing
