DESY is pursuing an ambitious laser-plasma injector option for its future PETRA IV synchrotron. The plasma injector will deliver 6 GeV electron beams for direct injection into the ring, offering a significant reduction in footprint and energy consumption.

I will present the conceptual design and cover efficiency, timing, and other relevant aspects. Furthermore, I will discuss technology challenges including drive laser and plasma accelerator performance. Finally, I will present our timeline and development roadmap, and discuss experimental steps towards realization, including the recent demonstration of active energy compression, that delivered sub-permille energy stability beams already suitable for injection at lower energies.
