Runaway electrons during a coil quench in stellarators
Pavel Aleynikov, Per Helander, HÃ¥kan M Smith
It is shown that avalanches of runaway electrons can arise in stellarators, even if there is no net toroidal current in the plasma or the magnetic-field coils, if the current in th…

Optimised stellarators with a positive radial electric field
Per Helander, Alan G. Goodman, Craig D. Beidler +2
We draw attention to an interesting possibility in the design and operation of stellarator fusion reactors, which has hitherto been considered unrealistic under burning-plasma cond…
