Description
The lateral position deviation between the electron beam and undulators will lead to an interaction area decrease in practical high-gain free electron laser (FEL) equipment. Corrector magnets can be modified in the FEL control system to regulate the electron beam trajectory and promote laser power. Tuning tasks are time-varying, drifting, and multi-dimensional, and manual tuning by operators takes lots of time and effort. This paper proposes an online optimization algorithm using a twin delayed deep deterministic policy gradient (TD3) to automatically optimize laser energy under ever-changing conditions.
