Confirmation of the topology of the Wendelstein 7-X magnetic field to better than 1:100,000
Abstract
Early stellarator designs suffered from high particle losses, an issue that can be addressed by optimization of the coils. Here the authors measure the magnetic field lines in the Wendelstein 7-X stellarator, confirming that the complicated design of the superconducting coils has been realized successfully.
