Electron-positron instabilities

New! Curvature-driven instability in electron-positron plasma may limit confinement in planned antimatter magnetic confinement schemes. Interestingly, Debye-scale physics stabilizes the instability and leads to a density limit similar in form to the Brillouin limit. See initial paper.

Original GS2 citations

The history of GS2 is described here. To credit the principal authors of GS2, papers that make use of GS2 can cite the following papers. The first describes the algorithms in Kotschenreuther's original linear version of the code, and the second paper shows an early application of Dorland's nonlinear version (and also references the first):

"Comparison of Initial Value and Eigenvalue Codes for Kinetic Toroidal Plasma Instabilities," M. Kotschenreuther, G. Rewoldt, and W.M. Tang, Comp. Phys. Comm. 88, 128 (1995).
"Electron Temperature Gradient Turbulence", W. Dorland, F. Jenko, M. Kotschenreuther, and B.N. Rogers, Phys. Rev. Lett. 85, 5579 (2000).
