Piecewise Omnigenous Stellarators

Physical Review Letters
In omnigenous magnetic fields, charged particles are perfectly confined in the absence of collisions and turbulence. For this reason, the magnetic configuration is optimized to be close to omnigenity in any candidate for a stellarator fusion reactor.

Physical origin of ultra-high neutral pressures in the Large Helical Device

Nuclear Fusion
Efficient particle exhaust remains a key challenge in magnetic confinement fusion, particularly in stellarators, where divertor neutral pressures are typically low. Recently, exceptionally high neutral pressures-up to 2.4 Pa-were measured in the divertor

Global fluid simulation of plasma turbulence in stellarators with the GBS code

Nuclear Fusion
The implementation of three-dimensional magnetic fields, such as the ones of stellarators, in the GBS code (Ricci et al 2012 Plasma Phys. Control. Fusion 54 124047; Giacomin et al 2022 J. Comput. Phys. 464 111294) is presented, and simulation results are
