This theme regroups several important topics regarding novel accelerator concepts in different fields: laserdriven and proton-driven PWFA (plasma wake field acceleration), including femtosecond arrival time control. On the one hand, laser-driven plasma wake field acceleration has been under study in many European institutes and universities mostly on an individual basis. In EuCARD-2, steps are made towards a collaborative experimental characterization and assessment of different methods of production of high brightness electron beams by several leading partners (CNRS-LOA, HZDR, INFN and USTRATH). On the road to higher energy acceleration, a two stage all optical acceleration process is characterized, as a first step towards chaining laser-driven PWFA cells.
