  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.

  The ICALEPCS MOCRAF workshop group has been created on www. to discuss about the organization of the ICALEPCS Motion Control pre-conference Workshop. Its purpose is to get feedback from attendees to make the workshop as interesting and as pleasurable as possible. This group will remain alive after the workshop to be the input for the future ICALEPCS MOCRAF meeting. The aim of the workshop is to be helpful to you the community and so we welcome input (*) on the content and style. After the previous workshop in at ICALEPCS in Melbourne it was suggested that more time should be put aside for interactive group discussions. We are proposing two talks per session each of around 15 to 20 minutes leaving 50 - 60 minutes for relevant discussion topics.
