title = "Pure electron plasmas in the CNT stellarator",
abstract = "Recent experimental, numerical, and theoretical results for non-neutral plasmas confined in the Columbia Non-neutral Torus stellarator are presented. Numerical equilibrium studies show that the electric potential is very sensitive to electrostatic boundary conditions. A numerical investigation of electron orbits indicates that variations in the electrostatic potential on magnetic surfaces cause unconfined orbits, despite a very strong radial electric field due to the non-neutrality. These findings are consistent with experimental results showing very rapid collisional transport. The installation of a conforming conducting boundary has reduced electrostatic potential variations and allowed to increase the confinement time by almost an order of magnitude, reaching 190ms. Observed transport jumps as well as ion driven instabilities are also discussed.",
