The National Ignition Facility (NIF) is the world's highest-energy laser fusion system. The extensive operational tools suite includes experimental setup, pre-shot machine readiness, setup change management, machine health alerts, laser performance and optimization modeling, and a post-shot robotic optics inspection and analysis to guide refurbishment. For example, experiments are setup by a campaign management tool and laser model that allows principal investigators to flexibly define experimental goals. The facility machine readiness is assessed with a configuration checker application by comparing the planned experiment with the hardware operational status for each of NIF's 192 beams. In addition, a restriction manager records and classifies conditional use restrictions on sub-systems categorized by location and types. The experimental goals are algorithmically compared with these categorized restrictions. Machine health and safety control points are directly verified at shot time by the status verifier application which is independent of the supervisory control system. Examples of these and other operational tool requirements and implementations will be presented.
