THE SOLEIL SYNCHROTRON LOCATED IN SACLAY IS A THIRD-GENERATION SYNCHROTRON OPTIMIZED IN THE MEDIUM X-RAY RANGE.
THE SYNCHROTRON MARS BEAMLINE IS AIMING TO INCREASE THE POSSIBILITIES OF RESEARCH IN BIOLOGY, PHYSICS AND CHEMISTRY ON RADIOACTIVE MATTER.
The CEA / SOLEIL synchrotron group (MARS beamline) was looking for a system to position a 5kg sample in the synchrotron beamline.
Symétrie offered a “goniometer” type precision positioning system.
This system consists of 5 high-precision axes: 3 linear axes and 2 rotary axes including a continuous rotation.
SPECIFICITIES OF THE PROJECT
■ High rigidity, the goniometer tilts around a horizontal axis from 0 to 90°
■ Linear accuracy < 2 µm
■ Peak-to-peak 3D sphere of confusion < 20 µm
■ High compactness
■ Slip ring including 8 contacts for the sample holder
This development has successfully integrated the specific constraints of space, environment and precision. The system is compatible with the standard control electronics used at SOLEIL (ControlBox).
