  PandABox is a development project resulting from a collaboration between Synchrotron SOLEIL and Diamond Light Source started in October 2015. The initial objective driving the project was to provide multi-channel encoder processing for synchronizing data acquisitions with motion systems in experimental continuous scans. The resulting system is a multi-purpose platform well adapted for multi-technique scanning and feedback applications. This flexible and modular platform embeds an industrial electronics board with a powerful Xilinx Zynq 7030 SoC (Avnet PicoZed), FMC slot, SFP module, TTL and LDVS I/Os and removable encoder peripheral modules. In the same manner, the firmware and software framework has been developed in a modular way to be easily configurable and adaptable. The whole system is open and extensible from the hardware level up to integration with control systems like TANGO or EPICS. This paper details the hardware capabilities, platform performance, framework adaptability, and the project status at both sites.

  The LIMA project started in 2009. The goal was to provide a software library for the unified control of 2D detectors. LIMA is a collaborative project involving synchrotrons, research facilities and industrial companies. LIMA supports most detectors used for X-ray detection or other scientific applications. Live display is supported via a video interface and most of the native video camera image formats are supported. LIMA provides a plug-in architecture for on-line processing which allows image pre-treatment before saving e.g. noise reduction algorithm or automatic X-ray beam attenuation during continuous scans. The library supports many file format including EDF, CBF, FITS, HDF5 and TIFF. To cope with increasing detector acquisition speed, the latest LIMA release includes multi-threaded, parallelized image saving with data compression (gzip or lz4). For even higher throughput a new design, based on a distributed multi-computer architecture, of the LIMA framework is envisaged. The paper will describe the LIMA roadmap for the coming years.

WEAPL04 Nanoprobe Results: Metrology & Control in Stacked Closed-Loop Systems 1028

  Over the course of four years, the Nanoprobe project worked to deliver prototypes capable of nm-precision and accuracy with long-range millimetric sample positioning in 3D- scanning tomography for long beamline endstations of Synchrotron Soleil and MAXIV. The ambition of the project necessitated a joint progress between several fields of expertise combining mechanics, metrology, motion control, and software programming. Interferometry in stage characterization has been a crucial point; not only to qualify motion errors but to actively integrate it into control systems with feedback and/or feedforward schemes in order to reduce XYZ position errors down to the nm- level. As such, a new way of characterizing rotation stages was developed and ultimately used in control schemes utilising the Delta Tau PowerPMAC platform. This paper details the obtained results as well as the methodology and approach of the project to achieve this.
