Abstract
The National Ignition Facility (NIF) is designed with its high-value optical systems in cassettes called line-replaceable Units (LRUs). Virtually all of NIF's active components are assembled in one of approximately 4000 electrical and optical LRUs that serve between two and eight of NIF's 192 laser beamlines. Many of these LRUs are optomechanical assemblies that are roughly the size of a telephone booth. The primary design challenges for this hardware include meeting stringent mechanical precision, stability, and cleanliness requirements. Pre-production units of each LRU type have been fielded on the first bundle of NIF and have been used to demonstrate that NIF meets its performance objectives. This presentation provides an overview of NIF LRUs-and their design and production plans for building out the remaining NIF bundles.
