The organization structure of EuPRAXIA-PP combines the expertise from many European labs and from different technical fields. The overall managerial concept of EuPRAXIA therefore implements a scenario where the international community comes together for a common design and construction of a European plasma accelerator facility, which shall be installed in two central locations for two complementary driver technologies (one for beam and one for laser drivers). Both sites share common technical designs, prototyping and production for many components.
