The stellarator concept is for toroidal currents to cancel out to zero, allowing plasma to float inside the magnetic coils. The magnetic cage of
the stellarator at W7-X is created by a ring of 50 superconducting magnetic coils. (Image credit: MPI for Plasma Physics)

It relies on superconducting materials which have zero electrical
resistance and have been revolutionizing magnet technology
for decades. Conventional superconductors require extremely
low temperatures, near absolute zero. Modern high-temperature
superconductors (HTS), however, can reach higher temperatures
and magnetic field strengths while also having significantly wider
design space, leading to less strict requirements. HTS technology
is at the forefront of leading tokamak developments and
is considered equally attractive for stellarators, which are less
constrained by current-driven operational limits.
This makes the relevant technology readiness levels for magnetic
confinement fusion power plants significantly higher than
for other approaches such as laser fusion, maintains Proxima,
with stellarators being one of the primary magnetic confinement
concepts. Building on the results from W7-X, and enabled by recent
advances in simulation and technology, fusion power plants
based on QI stellarators are now within reach, the company
believes.
