API Application Story TM Laser-based Metrology in Fusion Plasma Physics Picture: Max-Planck-Institut für Plasmaphysik, Dietmar Gust Laser-based 3D-metrology in Fusion Plasma Physics Industrial measurement systems in basic research areas Dr. Torsten Bräuer, Max-Planck-Institut für Plasmaphysik, Greifswald, Germany Very rarely is a research area as dependent on 3D-measurement technology in the set-up of its major experiments as fusion plasma physics. When one realises how highly complex these systems are, and how deeply industrial 3D laser measurement technology, and in particular the mobile...

Laser-based Metrology in Fusion Plasma Physics - 3

API Application Story TM Laser-based Metrology in Fusion Plasma Physics Symmetries: negative! The plasma vessel, which is surrounded by hot plasma at up to 100 million degrees, is reminiscent of a twisted, half-deflated bicycle inner tube of approx. 11 m at the large diameter and approx 1,5 m at the small diameter. The highly complex, threedimensional contour of the plasma vessel orientates itself to the geometry of the toroidal magnetic field generated on the Wendelstein 7-X. The field lines, which are comparable to the bars of the cage of a wild animal, form a cage that makes it...

Laser-based Metrology in Fusion Plasma Physics - 4

API Application Story TM Laser-based Metrology in Fusion Plasma Physics positioned anywhere in the line of sight of the port, the control of the connection of the inner pipe with the plasma vessel is a great challenge. In order to be able to measure the pipe to be welded onto the plasma vessel, a laser tracker must be able to look into the approx. 2-metre-long port from the outside. It must also be positioned directly in the axis of the port. A small laser tracker that can be flexibly mounted in its position is a decisive advantage here. The laser tracker is fitted to the support with...

Laser-based Metrology in Fusion Plasma Physics - 5

API Application Story TM Laser-based Metrology in Fusion Plasma Physics In the last few years, the build-up of the fusion system has moved well ahead with regard to the principal components, and the outer shell has become almost completely closed. The assembly of the Wendelstein 7-X is now concentrated on the installation of the fittings within the plasma vessel. Until recently, photogrammetric systems in combination with jointed measurement arms were used in the interior of the plasma vessel. Today, however, it appears that that the measurement during the installation in the interior of...
