NMR
Nuclear Magnetic Resonance uses vacuum insulated superconducting magnets at liquid Helium temperature. The SRG Technology can measure the insulation vacuum quality and its change over time, especially during manufacturing and in case of service (magnet at ambient temperature).
Grids / Cables
Superconducting cables are used for loss free electrical energy transport. Besides the efficiency gain, the power density is increased significantly, meaning the same power can be transferred through a small diameter cable ( cm² ) while conventional lines would have to use multiple wires over long distances (m²), especially in cities where it may be the only suitable method. Superconducting cables work at liquid Helium or liquid Nitrogen temperature, vacuum insulated. The vacuum insulated electrical power lines are “per definition long”, theses tubes have a very bad aspect ratio for the generation and measurement of vacuum. The SRG Technology should be able to measure the insulation vacuum quality at different points of the cable during manufacturing, in case of service and, in principle, products can be developed that measure continuously. Applications during operations need to be discussed with our applications specialists.
The page Cryo Technology contains a picture of our SRG VIM-1 in action at a vacuum insulated or vacuum jacketed pipe.
