XY Phi high load positioning system for fast 3D tomography in synchrotron | travel XY 230 x 340 mm, Phi unlimited, rotary radius 800 mm, load up to 100 kg
Laboratory / Analytics


Ultrastable positioning of extremely high loads

This rotation positioning system was specially developed for the 3D examination of particularly large and heavy materials in the synchrotron. Sample sizes up to 400 mm can be positioned with heavy loads up to 100 kg. Due to the ultra-stable design for a constant, high-precision rotation speed, 3D X-ray inspections can be realized much cheaper and faster.


Very fast inspections with a large rotation radius

  • Ideal for fast and economical 3D tomography in synchrotron with dimension up to 400 mm (rotation radius 800 mm)
  • Very constant rotation speed of 30°/s with an ultra-precise accuracy of 0.03°
  • Ultra-stable positioning for 3D observation of very high loads up to 100 kg
Optionally customizable:
  • Configurable for clean room ISO 14644-1 (up to class 1 on request)
  • Different traverse paths
  • Integration into the customer specific overall application
  • Immediate use with pre-configured controller incl. exemplary software

Fields of application

This system has been supplied for various applications over many years for e.g.: Basic research, investigation of biological samples close to native state, sample manipulation, material research, material analysis, beamline, accelerator.

In the initial development, this positioning system was developed for sample examination in the synchrotron. Large material samples were to be imaged three-dimensionally using a tomography technique. A synchrotron in Switzerland was used to generate the very short wavelength X-rays. The challenge was the expected mass of the samples of up to 80 kg and their dimension of up to 400 mm, which results in a required rotation radius of 800 mm. It must also be possible to move this rotating unit by the longitudinal dimension of the specimen. In the direction of movement Y, a stroke of 340 mm is required.
