- W2066387084 abstract "An important difference between the classical collision operator, C(f), and Kaufman’s quasi-linear diffusion operator in action space, D(f), is that only the former conserves particles, momentum, and energy at each spatial point. The nonlocal character of action-space diffusion allows all transport fluxes to be expressed directly in terms of appropriate moments of D. Thus, a general description of quasi-linear diffusion and convection across flux surfaces in any collisionless, axisymmetric toroidal system is obtained, in terms of scale factors relating the invariant surfaces to the flux surfaces. Several analogues to the neoclassical problem are apparent, including the collisionless version of the Ware–Galeev pinch effect, whose derivation in action space is especially straightforward. Toroidicity modifies not only particle orbits but also the spatial structure of the fluctuations, and both modifications affect the resulting transport in an important way. The use of appropriate action-angle variables automatically includes the orbital effects; crucial features of the toroidal eignmode structure are incorporated by use of the ballooning representation. This makes the fastest radial variation explicit, in terms of a single parameter describing the degree to which submodes localized on different rational surfaces overlap. The variation on slower length scales, and the overall spectral amplitude, are not determined. The radial particle flux corresponding to a Maxwellian distribution function is displayed and its dependence on properties of the spectrum is analyzed." @default.
