The goal of fusion energy scientists is to fashion a strong enough magnetic cage to trap the turbulent plasma griffins that guard the hidden gold...

What's new:

Vortex Waltz May, 2009: "Vortex Waltz", an entry by graduate student Luc Peterson and I in the Princeton University Art of Science exhibit. Press coverage included the Italian newspaper Il Sole24Ore.

November, 2007: "Gyrokinetic Theory and Simulations of Experiments", G. W. Hammett, review talk, 2007 APS Division of Plasma Physics Annual Meeting, Orlando, Nov. 12-16.

General public interest:

Don't count out the old physicists.

"Current Status of Fusion Energy Research & Related Plasma Turbulence Studies", G.W. Hammett, Kavli Institute for Theoretical Physics", U.C. Santa Barbara, May 19, 2005. WebCam & Audio. This talk has a broad introduction aimed at physicists outside of fusion energy research.

Assorted course materials:

Note that I only have some of the course material online. We also use a number of books and other notes handed out in class.

Princeton graduate course AST559/APC539: Turbulence and Nonlinear Processes in Fluids and Plasmas (notes available only at Princeton, for now) 2011, 2014
Princeton graduate course AST554 Irreversible Processes in Plasmas (Princeton only, for now) 2007- (co-taught with Prof. John Krommes in 2001)
Princeton graduate course AST551/MAE541 General Plasma Physics I co-taught with Prof. Nat Fisch, 1995-2000, 2002-2005
My A Physics Formulary (incomplete, mostly plasma physics and math at this point. Foldable booklet version (for two-sided printing). LaTeX source files.
The MFE Formulary, a good collection initiated by Hartwig and Podpaly while they were Ph.D. students at MIT>
The NRL Plasma Formulary.
Computational Physics Tutorial given at the Abdus Salam International Centre for Theoretical Physics in Trieste, 2001, with Prof. Bill Dorland.
Other assorted course notes on my PPPL web site or my my Princeton wiki pages.

Technical info of interest to specialists:

Nonlinear continuum gyrokinetic codes: Candy & Waltz's GYRO, Dorland & Kotschenreuther's GS2's wiki (Astro version: AstroGK), Jenko's GENE.

Ammar Hakim and I are exploring several advanced methods, including certain types of Discontinuous Galerkin algorithms, that may be helpful in the difficult problem of simulating gyrokinetic turbulence in the edge region of fusion devices. See Ammar Hakim's Simulation Journal .

Edge Simulation Laboratory
Center for the Study of Plasma Microturbulence
Center for Multiscale Plasma Dynamics (CMPD) (before 2009)

Griffin Picture

In Greek mythology, the griffin had the head and wings of an eagle and the body of a lion, and jealously watched over a storehouse of gold in Scythia.
