劳伦斯利弗莫尔国家实验室的国家点火装置是一个正在建设中的体育场大小的设施，将包含一个192束、1.8兆焦耳、500太瓦的紫外激光系统以及一个直径10米的靶室，该靶室有多个实验诊断室。NIF是世界上最大和最具活力的激光实验系统，为研究惯性约束聚变（ICF）和极端能量密度和压力下的物质提供了科学中心。NIF的激光束被设计成将聚变目标压缩到热核燃烧所需的条件，释放出比引发聚变反应所需的更多的能量。NIF由24个独立的光束束组成，每个光束束使用激光硬件，这些激光硬件被模块化为6000多个可更换单元，如光学组件、激光放大器和包含60，000个控制和诊断点的多功能传感器包。NIF由大型集成计算机控制系统（ICCS）运行，其架构按捆绑包分区，分布在800多个前端处理器和50个监控服务器之间。NIF的自动化控制子系统是从一个基于CORBA分布的通用面向对象软件框架构建的，该框架将软件部署在计算机网络上，并实现不同语言和目标体系结构之间的互操作。在过去的一年中，已经部署了一个镜头自动化框架，以使用ICCS协调和自动化在NIF执行的镜头。2006年12月，一个完整的48束NIF光束的集群同时发射，表明独立的束控制系统将按比例扩大到192束的全尺寸。目前，72个光束已投入使用，并已展示了1.4兆焦耳的红外光能力。在接下来的2年里，控制系统将扩大，为2009年项目完成做准备，包括目标区域系统的自动化，包括最终光学系统、目标定位器和诊断。在2010年开始的国家点火运动（NIC）中，支持聚变点火射击的其他能力将包括低温靶系统、靶诊断和综合实验射击数据分析，以及数据可视化和存档工具。本演讲讨论了控制系统实施的现状，并讨论了在点火路径上完成控制系统的计划。

The National Ignition Facility (NIF) at the Lawrence Livermore National Laboratory is a stadium-sized facility under construction that will contain a 192-beam, 1.8-MJ, 500-TW, ultraviolet laser system together with a 10-m diameter target chamber with room for multiple experimental diagnostics. NIF is the world's largest and most energetic laser experimental system, providing a scientific center to study inertial confinement fusion (ICF) and matter at extreme energy densities and pressures. NIF's laser beams are designed to compress fusion targets to conditions required for thermonuclear burn, liberating more energy than required to initiate the fusion reactions. NIF is comprised of 24 independent bundles of eight beams each using laser hardware that is modularized into more than 6000 line replaceable units such as optical assemblies, laser amplifiers, and multi-function sensor packages containing 60,000 control and diagnostic points. NIF is operated by the large-scale Integrated Computer Control System (ICCS) in an architecture partitioned by bundle and distributed among over 800 front-end processors and 50 supervisory servers. NIF's automated control subsystems are built from a common object-oriented software framework based on CORBA distribution that deploys the software across the computer network and achieves interoperation between different languages and target architectures. A shot automation framework has been deployed during the past year to orchestrate and automate shots performed at the NIF using the ICCS. In December 2006, a full cluster of 48 beams of NIF was fired simultaneously, demonstrating that the independent bundle control system will scale to full scale of 192 beams. At present, 72 beams have been commissioned and have demonstrated 1.4-MJ capability of infrared light. During the next 2 years, the control system will be expanded in preparation for project completion in 2009 to include automation of target area systems including final optics, target positioners and diagnostics. Additional capabilities to support fusion ignition shots in a National Ignition Campaign (NIC) beginning in 2010 will include a cryogenic target system, target diagnostics, and integrated experimental shot data analysis with tools for data visualization and archiving. This talk discusses the current status of the control system implementation and discusses the plan to complete the control system on the path to ignition.
