The French Atomic Energy Commission(CEA)has just built an integration platform outside the LMJ facility in order to assemble the various components of the Integrated Control Command System(ICCS). The talk gives an overview of this integration platform and the qualification strategy based on the use of equipment simulators, and focuses on several tools that have been developed to integrate each sub-system and qualify the overall behavior of the ICCS. Each delivery kit of a sub-system component(Virtual Machine, WIM, PLC,.) is scanned by antivirus software and stored in the delivery database. A specific tool allows the deployment of the delivery kits on the hardware platform (a copy of the LMJ hardware platform). Then, the TMW(Testing Management Workstation) performs automatic tests by coordinating the equipment simulators behavior and the operator’s behavior. The tests configurations, test scenarios and test results are stored in another database. Test results are analyzed, every dysfunction is stored in an event data base which is used to perform reliability calculation of each component. The qualified software is delivered on the LMJ to perform the commissioning of each bundle.

The French Commissariat à l’Énergie Atomique (CEA) is currently building the Laser Megajoule (LMJ), a 176-beam laser facility, at the CEA Laboratory CESTA near Bordeaux. It is designed to deliver about 1.4 MJ of energy to targets for high energy density physics experiments, including fusion experiments. The assembly of the first lines of amplification is almost achieved and functional tests are planed for next year. The first part of the presentation is a photo album of the progress of the assembly of the bundles in the four laser bay, and the equipements in the target bay. The second part of the presentation illustrates a particularity of the LMJ commissioning: a secondary control room is dedicated to successive bundles commissioning, while the main control room allows shots and fusion experiments with already commissioned bundles

The French Commissariat à l’Énergie Atomique et aux Énergies alternatives (CEA) is currently building the Laser Megajoule (LMJ). This facility is designed to deliver laser energy to targets for high energy density physics experiments, including fusion experiments. The Integrated Timing and Triggering System (ITTS) is one of the critical LMJ components, in charge of timing distribution for synchronizing the laser beams and triggering the shot data acquisitions. The LMJ ITTS Control System provides a single generic interface to its users at the Supervisory level, built around the key concept of “Synchronized Channels Group”, a set of delay channels triggered simultaneously. Software common components provide basic mechanisms: communication with its users, channel registration User-defined delays are specified with respect to a given reference(target chamber center, quadruplet or beam reference times), these delays are then translated into hardware delays according to different parameters such as electronic cards temperatures(for thermal drift correction) and transit delays. Equipments are mainly off-the-shelf timing equipments delivering trigger signals with jitter down to 15ps rms.
