The National Ignition Facility (NIF) is a $1.2-billion laser facility under construction at Lawrence Livermore National Laboratory (LLNL) in California. The new laser will be the latest in a series of high-power laser facilities used for research in inertial confinement fusion. A key component of the DOE's Stockpile Stewardship and Management Program, the NIF will help maintain the U.S. stockpile without underground nuclear explosives testing. The NIF is the next scientific step to evaluating inertial fusion energy as an environmentally attractive energy source. NIF will provide insight into the origin of our universe by creating conditions similar to those at the center of the Sun and other stars. When completed, the NIF will house 192 beamlines that run the length of the facility and deliver 2 MegaJoule pulses of optical energy on a fusion fuel capsule the size of a BB in a pulse 25 nanoseconds long. The NIF will occupy a building that is 704 feet long, 403 feet wide, and 85 feet tall, about the size of a football stadium (NIF would just fit inside the New Orleans Superdome). The NIF Integrated Computer Control System integrates about 40,000 control points. ICCS must be highly automated and robust, and must operate continuously around the clock. We are using object-oriented modeling to specify our software, and Ada-95 to implement the distributed control system. The ICCS is being developed using an iterative approach. This technique is effective for projects whose requirements are not fully known until late in the project development. Five iterations are planned prior to the first facility deployment of the ICCS software. Risks to the control system software are managed through a modern object-oriented software framework that is used to construct all applications and that will be extensible and maintainable throughout the project life cycle. This framework is reusable across multiple applications (and indeed other projects) and offers interoperability among computers and operating systems by leveraging a common object request broker architecture (CORBA). The software development project is described on the web at http://lasers.llnl.gov/lasers/nif/ICCS/index.html -- John Woodruff N I F \ ^ / Lawrence Livermore National Lab =====---- < 0 > 510 422 4661 / v \
