Codes that calculate the trajectories of particles in complicated electromagnetic fields often include spectral methods, which take advantage of the speed of FFTs to rapidly solve for the fields. In this case, Hermite tricubic interpolation can be us

The Columbia Non‐neutral Toms (CNT) is a simple stellarator being used to study non‐neutral plasmas. At low neutral pressures these plasmas are pure electron plasmas. In this paper some studies of the equilibrium and transport of these plasmas wi

An instability has been observed in non‐neutral plasmas confined on magnetic surfaces in the presence of a finite ion fraction [Phys. Rev. Letters 100, 065002 (2008)]. The dependence of the frequency and amplitude of the instability on neutral pres

Recently the measured confinement time in the Columbia Non‐neutral Torus (CNT) has been increased by nearly an order of magnitude to 190 ms. Previously, enhanced transport caused in part by the mismatch of constant potential and magnetic surfaces l

The Columbia Non‐neutral Torus is a stellarator devoted to non‐neutral and electron‐positron plasma research. Confinement and transport processes have been studied in some detail now, and an understanding of these processes has emerged. Transpo
