Abstract : The research program has used laboratory experiments and theoretical models to investigate MHD equilibria relevant to solar and space physics, dynamical behavior at the MHD scale (i.e., motion, deformation, and topological changes of the macroscopic structure such as expansion of a solar corona loop),MHD instabilities (e.g., kink and Rayleigh-Taylor instabilities), high frequency waves that are generated by transients associated with the instabilities (e.g., generation of whistler waves), particle energization (e.g., electron and ion heating, changes in ionization state, emission of energetic photons), complex particle orbits in an electro-magnetic field (e.g., extension of adiabatic invariant concepts, stochastic heating, Hamiltonian concepts, relativistic particle motion in a circularly polarized wave), and new diagnostic techniques (e.g., coded aperture imaging, determining wave-vector k from single spacecraft measurements). Thirteen papers have been published in scientific journals and one additional paper has just been submitted.
