   The issue with the efficiency begins already with the high-power lasers that are needed for wakefield acceleration, which have a typical wall-plug efficiency of ~0.1%. From that, only about ~1% of the laser pulse energy gets transferred int

   It is already possible to reach 800 MeV (the energy for an EUV FEL according to the article) with single-stage laser wakefield accelerators. The problem is doing so with sufficient beam quality, reproducibility and repetition rate. The ener

   That's very useful, thanks!

   Are the tolerances of the optimum important in your case? (i.e., how sensitive it is to errors in the design parameters) If so, did you use any method to incorporate this information into the optimization?

   It's also very useful for simulation-based optimization. As an example, we use it extensively for the design of particle accelerators, where the simulations are typically expensive and need to run on supercomputers. We have built our o
