  Funding: This work has been performed in the framework of the R&D collaboration between the Nanoscopium (Synchrotron SOLEIL, St Aubin, France) and NanoMAX (MAXIV, Lund Sweden) beamlines.
Since 2012, Synchrotron SOLEIL in France and MAXIV in SWEDEN started a collaboration to develop a high precision scanning hard X-ray nanoprobe system which is under construction at SOLEIL. This scanning nanoprobe is completed by a series of positioning stages for stacked Fresnel Zone Plate focusing optics, designed in order to provide a quality of the nano-beam adapted to the high precision of the xyzƟ sample positioning stage. This nanoprobe set-up aims to reach some deca-nanometers spatial resolution for 2D and 3D measurements. The implementation of fast scanning is one of the challenges of this system. Over the last two years several positioning stages have been characterized and compared to the wished static and dynamic requirements applying thorough metrology methods. This paper presents some test results obtained and the control architecture defined during the last two years while building the first prototype of the sample positioning stage.

  SOLEIL is continuously optimizing its 29 beamlines in order to provide its users with state of the art synchrotron radiation based experimental techniques. Among the topics addressed by the related transversal projects, the enhancement of the computing tools is identified as a high priority task. In this area, the aim is to optimize the beam time usage providing the users with a fast, simultaneous and multi-technique scanning platform. The concrete implementation of this general concept allows the users to acquire more data in the same amount of beam time. The present paper provides the reader with an overview of so call 'Flyscan' project currently under deployment at SOLEIL. It notably details a solution in which an unbounded number of distributed actuators and sensors share a common trigger clock and deliver their data into temporary files. The latter are immediately merged into common file(s) in order to make the whole experiment data available for on-line processing and visualization. Some application examples are also commented in order to illustrate the advantages of the Flyscan approach.
