| TUB005 | Experimental Data Storage Management in NeXus Format at Synchrotron SOLEIL | 75 |

At Synchrotron SOLEIL, twenty Beamlines are already in operation and produce daily a lot of experimental data files in a range from a few Mb up to 10Gb. Almost all experimental data are stored using the NeXus data format [1]. It is a logical format based on a physical format HDF, able to store any kind of scientific data produced in Neutron or Synchrotron sources. Besides, the NeXus format allows recording experimental data together with all needed contextual like experiment, instrumentation, sample, user's information' Several tools are developed or under development at SOLEIL: a web data browser to retrieve, browse and download data, a command line tool used to export data from NeXus in ASCII or binary data file… The storage system is fully integrated into the Tango bus [2] through a set of dedicated devices. Therefore it's possible to record any data coming from Tango devices into a NeXus file. The storage system is designed to allow recording data from various data sources using a plug-in system. In terms of hardware, a high availability system with the innovator concept of cellular storage "Active Circle" [3] is used since December 2006.

SOLEIL* is a 3rd generation Synchrotron Source located in France near Paris. Early 2009, it delivers photon beam to 20 beamlines with global reliability better than 95%. We will describe the status of the installation and operation of the control systems for the accelerators and beamlines. Hardware status for motion systems, controls and data acquisitions will be given. All software developments are based on the Tango framework, using it, not only as a "traditional control system" but in a more general way as a service-oriented middleware interconnecting SOLEIL's applications. We will show figures and examples of the TANGO software components developed and used. On the supervision layer, SOLEIL uses an industrial SCADA (GlobalScreen) as an integration tool of the JavaBeans components developed with the TANGO ATK graphical framework. Supervision applications are the result of a collaborative work between "pure software developers" and "occasional" supervision applications developers. The work organization, the software architecture and current status at SOLEIL will be given. We will conclude with some statistics about Controls stability and quality after 3 years of operation.
