Laser-Plasma Accelerators (LPA) exploits electric fields exceeding 100 GV/m to produce ultrashort electron bunches. These unique features open up new prospects for ultrafast-physics and the development of compact accelerators, for instance. Yet, LPAs suffer from an inferior beam quality and stability. One of the reasons for these weaknesses is a poor control of the target properties. Task 6.3 aims at developing and test targets of superior quality for extending the beam energy and improving its reliability. Here we report on Milestone MS23 which comprises the target manufacturing and characterisation.
