A superconducting helical undulator prototype reaches magnetic fields as high as 2.5 T during its tests in a stream of 10 K He gas. REBCO bulk high-temperature superconductors, organized in a staggered array geometry, are key to this result.

The Hosking integral, which controls the decay of nonhelical magnetic turbulence, is adapted to turbulence that is fully helical but balanced by fermion chirality.
