Modern laser and accelerator systems demand fast, precise, and scalable multi-input multi-output (MIMO) feedback control. As requirements extend into high-repetition-rate and nonlinear regimes, traditional strategies increasingly struggle to deliver the necessary speed and adaptability. This talk presents two cases where machine learning (ML) enhances deterministic feedback control. In both,...
This talk presents Safe Extremum Seeking (Safe ES), a robust n-dimensional adaptive control method, applied to automatic tuning and optimization tasks of accelerators while guaranteeing that the system remains within safe operating conditions. A key strength of Safe ES is its ability to handle safety measures that are analytically unknown. For instance, the algorithm can adaptively tune...
Recent electron storage ring light sources continue to push towards increasingly lower electron beam sizes. In the present work, we report on the measurements of the electron beam emittance (sub 50 pm rad) achieved at the Advanced Photon Source Upgrade (APS–U), as well as its standing among electron storage ring light sources. We include a brief status update on the beam size monitor beamline...
