Fusion energy: Progress, partnerships, and the path to deployment
Over the past decade, fusion energy has moved decisively from scientific aspiration toward a credible pathway to a new energy technology. Thanks to long-term federal support, we have significantly advanced our fundamental understanding of plasma physics—the behavior of the superheated gases at the heart of fusion devices. This knowledge will enable the creation and control of fusion fuel under conditions required for future power plants. Our progress is exemplified by breakthroughs at the National Ignition Facility and the Joint European Torus.

A complete description of a system in equilibrium is provided by the Grand Canonical Distribution. But, systems are generally not in statistical equilibrium. We shall consider the case of an ideal gaz of charged particles. The linear theory of transport determines the 3 × 1 matrix of dissipative fluxes [hat]Jr namely, the electric current and the electronic and ionic heat fluxes, in terms of a 3 × 1 matrix of thermodynamic forces [hat]X defined by the electric field and the gradient of the densities and temperatures. The components of the 3 × 3 matrix of tensors [hat]Lrs of the linear flux-force relations [hat]Jr = [summation]s=19[hat]Lrs[hat]X define the set of transport coefficients. They are evaluated for an ion-electron magnetized plasma in the framework of the statistical mechanics of charged particles starting from the Landau kinetic equation.
