The Advanced Radiographic Capability (ARC) currently under development for the National Ignition Facility (NIF) will provide short (1-50 picoseconds) ultra high power (>1 Petawatt) laser pulses used for a variety of diagnostic purposes on NIF ranging from a high energy x-ray pulse source for backlighter imaging to an experimental platform for fast-ignition. A single NIF Quad (4 beams) is being upgraded to support experimentally driven, autonomous operations using either ARC or existing NIF pulses. Using its own seed oscillator, ARC generates short, wide bandwidth pulses that propagate down the existing NIF beamlines for amplification before being redirected through large aperture gratings that perform chirped pulse compression, generating a series of high-intensity pulses within the target chamber. This significant effort to integrate the ARC adds 40% additional control points to the existing NIF Quad and will be deployed in several phases over the coming year. This talk discusses some new unique ARC software controls used for short pulse operation on NIF and integration techniques being used to expedite deployment of this new diagnostic.

The National Ignition Facility (NIF) is operated by the Integrated Computer Control System in an object-oriented, CORBA-based system distributed among over 1800 front-end processors, embedded controllers and supervisory servers. At present, NIF operates 24x7 and conducts a variety of fusion, high energy density and basic science experiments. During the past year, the control system was expanded to include a variety of new diagnostic systems, and programmable laser beam shaping and parallel shot automation for more efficient shot operations. The system is also currently being expanded with an Advanced Radiographic Capability, which will provide short (<10 picoseconds) ultra-high power (>1 Petawatt) laser pulses that will be used for a variety of diagnostic and experimental capabilities. Additional tools have been developed to support experimental planning, experimental setup, facility configuration and post shot analysis, using open-source software, commercial workflow tools, database and messaging technologies. This talk discusses the current status of the control and information systems to support a wide variety of experiments being conducted on NIF including ignition experiments.

Used actively by the National Ignition Facility since 2004, the JIRA issue tracking system from Atlassian is now used for 63 different projects. NIF software developers and customers have created over 80,000 requests (issues) for new features and bug fixes. The largest NIF software project in JIRA is the Integrated Computer Control system (ICCS), with nearly 40,000 issues. In this paper, we’ll discuss how JIRA has been customized to meet our software development process. ICCS developed a custom workflow in JIRA for tracking code reviews, recording test results by both developers and a dedicated Quality Control team, and managing the product release process. JIRA’s advanced customization capability have proven to be a great help in tracking key metrics about the ICCS development efforts (e.g. developer workload). ICCS developers store software in a configuration management tool called AccuRev, and document all software changes in each JIRA issue. Specialized tools developed by the NIF Configuration Management team analyze each software product release, insuring that each software product release contains only the exact expected changes.
