The extreme physics of targets shocked by NIF's 192-beam laser is observed by a diverse suite of diagnostics. Many diagnostics are being developed by collaborators at other sites, but ad hoc controls could lead to unreliable and costly operations. A diagnostic control system (DCS) framework for both hardware and software facilitates development and eases integration. Each complex diagnostic typically uses an ensemble of electronic instruments attached to sensors, digitizers, cameras, and other devices. In the DCS architecture each instrument is interfaced to a low-cost WINDOWS XP processor and JAVA application. Each instrument is aggregated with others as needed in the supervisory system to form an integrated diagnostic. The JAVA framework provides data management, control services, and operator graphical user interface generation. DCS instruments are reusable by replication with reconfiguration for specific diagnostics in extensible markup language. Advantages include minimal application code, easy testing, and high reliability. Collaborators save costs by assembling diagnostics with existing DCS instruments. This talk discusses target diagnostic instrumentation used on NIF and presents the DCS architecture and framework.
通过一系列不同的诊断方法来观测由国家点火装置（NIF）的192束激光冲击的靶材的极端物理过程。许多诊断方法是由其他机构的合作者开发的，但临时控制可能会导致操作不可靠且成本高昂。一个针对硬件和软件的诊断控制系统（DCS）框架有助于开发并简化集成过程。每个复杂的诊断方法通常使用一组连接到传感器、数字化仪、相机和其他设备的电子仪器。在DCS架构中，每个仪器都与一个低成本的WINDOWS XP处理器和JAVA应用程序相连。在监控系统中，每个仪器根据需要与其他仪器聚合在一起，以形成一个集成诊断。JAVA框架提供数据管理、控制服务以及操作员图形用户界面生成。DCS仪器可通过使用可扩展标记语言进行重新配置来复制，从而实现重用。优点包括最少的应用程序代码、易于测试以及高可靠性。合作者通过使用现有的DCS仪器组装诊断设备来节省成本。本次演讲讨论了NIF上使用的靶材诊断仪器，并介绍了DCS架构和框架。
