Optimizing Particle-In-Cell simulations of laser-plasma accelerators — •Laurids Jeppe¹, Sören Jalas¹, Manuel Kirchen¹, and Andreas R. Maier² — ¹Center for Free-Electron Laser Science and Department of Physics, Universität Hamburg — ²Deutsches Elektronen Synchrotron (DESY)

Designing experiments for laser-plasma acceleration via simulations is typically an expensive task due to the complexity of the physics involved. Here, we use the GPU-accelerated, quasi-3D Particle-In-Cell code FBPIC in a boosted frame to reduce the computational cost of such simulations and combine it with Bayesian Optimization to efficiently optimize LPA experiments. This approach is applied to different example cases to show its robustness and flexibility.
