  SOLEIL is a third generation synchrotron radiation source located near Paris in France. REVOLUTION (REconsider Various contrOLler for yoUr motion) is the motion controller upgrade project currently in progress at SOLEIL. It was initiated to maintain the facility operations by addressing the risk of hardware obsolescence in motion control but at the same time making room for complex applications requirements to face new high performance challenges. In order to achieve these considerations, SOLEIL's strategy move was to go from a single controller for all applications to two motion controllers. A first Controller GALIL DMC-4183 was chosen to succeed the previous version DMC-2182. Both controllers can be integrated in the existing architecture with little hardware and software adaptation enabling full compatibility with the existing architecture. A second controller, Delta Tau Power Brick, has been selected as a HIGH PERFORMANCE solution providing advanced functionality. The CLASSIC controller upgrade is about to be completed and the integration of Power Brick into the SOLEIL control system is ongoing. The system complexity is abstracted by embedding processing functions into low-level code and giving end-users a simple high-level interface. The work done to structure the interfacing and standardization of the controller are detailed in this paper.

  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.

  Synchrotron SOLEIL and Diamond Light Source are two third generation light sources located respectively in France and the UK. In the past 5 years, both facilities separately developed their own platform permitting encoder processing to synchronize motion systems and acquisition during experiments, SPIETBOX by SOLEIL and Zebra by Diamond. New operational requirements for simultaneous and multi-technique scanning, and support of multiple encoder standards have been identified by both institutes. In order to address these a collaborative project has been initiated between SOLEIL and Diamond to realize a new 'Position and Acquisition' processing platform, called PandA. The PandA project addresses current systems' limitations in term of obsolescence and need for more processing power. Its design is going to be a 1U standalone system powered by a Xilinx Zynq SoC to implement a configurable set of logic functionalities. It will provide a flexible and open solution to interface different third party hardware (detectors and motion Controllers). This paper details the organization of this collaboration, sharing technical leadership between both institutes and the status of the project.
