GALADRIEL: A facility for advancing engineering science relevant to rep-rated high energy density physics and inertial fusion energy experiments.

Many current and upcoming laser facilities used to study high-energy-density (HED) physics and inertial fusion energy (IFE) support operating at high rep-rates (HRRs) of ∼0.1-10 Hz, yet many diagnostics, target-fielding strategies, and data storage methods cannot support this pace of operation. Therefore, established experimental paradigms must change for the community to progress toward rep-rated operation.

Dynamic input shaping and image motion compensation for a dual-mirror system.

This paper shows that the task of trajectory planning for a dual-mirror optical pointing system with mechanical vibrations greatly benefits from carefully designed dynamic input signals, especially when high bandwidth throughput is required. The optical pointing system consists of two fast steering mirrors (FSMs) for which dynamically coupled input signals are designed, while adhering to mechanical and input signal constraints. A linear programming problem is used to compute the dynamic input signal for each FSM, with one acting as an image motion compensation device.
