Description
The Integrated Computer Control System (ICCS) at the National Ignition Facility (NIF) manages devices essential to fusion ignition experiments, including 488 specialized cameras supporting beam alignment, target alignment, cryogenic layering, optics damage inspection, collision avoidance, and other key processes. These heterogeneous camera systems, sourced from multiple vendors, use varied bus technologies and Windows-based proprietary SDKs, posing challenges to integrate into a unified control architecture. To address this, ICCS adopted a diskless Front End Processor (FEP) platform using Linux and open-source camera control libraries*. Leveraging a network-booted Linux environment and community-supported video drivers, ICCS integrated diverse vendor hardware while enabling rapid adoption of new camera models. Consolidating multiple cameras onto single FEPs improved maintainability and reliability through strategic grouping. Open-source libraries also position NIF as a contributor to the broader controls community. This modernization demonstrates a systematic approach to integrating dissimilar hardware components across a high-stakes facility. By bridging various proprietary protocols, consolidating scattered device controls, and leveraging community-supported software, ICCS achieves a maintainable, expandable architecture for key imaging and streaming functions.
