A promising application would be to use a laser-plasma accelerator as an injector for a synchrotron light source. Yet, the energy spread and jitter of the laser-plasma beam pose a significant difficulty for an efficient injection. In this paper we propose a design of a prototype injector to deliver 500 MeV low-intensity electron bunches to the DESY-II electron synchrotron. The design utilizes presently available conventional accelerator techn","authors_text":"A. Ferran Pousa, A. Martinez de la Ossa, A. R. Maier, I. Agapov, J. Osterhoff, L. Jeppe, M. Kirchen, M.
