An increasing number of SOLEIL beamlines need to use in parallel several detection techniques, which could involve 2D area detectors, 1D fluorescence analyzers, etc. For such experiments, we have implemented Distributed Fast Acquisition Systems for Multi Detectors. Data from each Detector are collected by independent software applications (in our case Tango Devices), assuming all acquisitions are triggered by a unique Master clock. Then, each detector software device streams its own data on a common disk space, known as the spool. Each detector data are stored in independent NeXus files, with the help of a dedicated high performance NeXus streaming C++ library (called NeXus4Tango). A dedicated asynchronous process, known as the DataMerger, monitors the spool, and gathers all these individual temporary NeXus files into the final experiment NeXus file stored in SOLEIL common Storage System. Metadata information describing context and environment are also added in the final file, thanks to another process (the DataRecorder device). This software architecture proved to be very modular in terms of number and type of detectors while making life of users easier, all data being stored in a unique file at the end of the acquisition. The status of deployment and operation of this "Distributed Fast Acquisitions system for multi detector experiments" will be presented, with the examples of QuickExafs acquisitions on the SAMBA beamline and QuickSRCD acquisitions on DISCO. In particular, the complex case of the future NANOSCOPIUM beamline will be developed.

Time resolved experiments are one of the major services that synchrotrons can provide to scientists. The short, high frequency and regular flashes of synchrotron light are a fantastic tool to study the evolution of phenomena over time. To carry out time resolved experiments, beamlines need to synchronize their devices with these flashes of light with a jitter shorter than the pulse duration. For that purpose, Synchrotron SOLEIL has developed the TimBeL board fully interfaced to TANGO framework. This paper presents the main features required by time resolved experiments and how we achieved our goals with the TimBeL board.
