Flow damping in stellarators close to quasisymmetry
Ivan Calvo, Felix I. Parra, J. L. Velasco +1
Quasisymmetric stellarators are a type of optimized stellarators for which flows are undamped to lowest order in an expansion in the normalized Larmor radius. However, perfect quas…
Optimizing stellarators for large flows
Ivan Calvo, Felix I. Parra, J. Arturo Alonso +1
Plasma flow is damped in stellarators because they are not intrinsically ambipolar, unlike tokamaks, in which the flux-surface averaged radial electric current vanishes for any val…
When omnigeneity fails
Felix I. Parra, Ivan Calvo, Jose Luis Velasco +1
A generic non-symmetric magnetic field does not confine magnetized charged particles for long times due to secular magnetic drifts. Stellarator magnetic fields should be omnigeneou…
