1 Experimental tasks Spectra Extend to small scale; wavenumber dependence (Taylor hyp.); density, flow Verify existence of inertial range Determine if decorrelation rate has dependence on B 0 Bispectrum in small scales, response to perturbation Measure anisotropy in small scales or B 2 (k, k | |, ) Physics of two high frequency subranges Dissipation? two-fluid effects? kinetic Alfvén wave? Driving sources besides tearing High k in PPCD, electrostatic, edge localized MRX: b/B ~ 1 region - effect of guide field on Alfvén waves, anisotropy, etc. MRX, SSPX, SSX: decaying turbulence - validity of Kulsrud magnetogenesis Transport: / | | ?. is there any resonant particle transport?

2 Theory Properties of turbulence under variation of mean field strength in spectra that peak at low k, and high k Measurement of spectral energy transfer Correlation to wave physics Effect of collisionless damping on spectrum; effect of anisotropy on dissipation Analytic theory for anisotropic spectrum in RMHD (a la quasi geo turb) Inverse cascade analysis closure theory - do Alfvénic interactions induce inverse energy cascade? Compressible turbulence - issues? Magnetic fluctuations, density distribution Thermal conductivity Braginskii, stochastic field Two fluid (Hall effects) Explanation of large for cosmic rays Thermal conductivity vs. electron diffusivity in chaotic field?

3 Theory continued Mirror spectrum Diffusion in multi-scale tangled field - firmer footing? Use of MHD turbulence measurements in transport theories? Checking of diffusion and heat conduction theories with experiments? MST, MRX Full 3D simulations of heat transport (collisions, e-e energy exchange, etc.)
