Division Spotlight
Accelerator Applications
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

Christmas Night
Twas the night before Christmas when all through the houseNo electrons were flowing through even my mouse.
All devices were plugged in by the chimney with careWith the hope that St. Nikola Tesla would share.

Direct numerical simulations in fully three-dimensional geometry have been performed in order to investigate effects of both the parallel flow to the magnetic field lines discarded in the reduced equations and the parallel thermal conductivity on the nonlinear evolution of interchange instability in a low- magnetohydrodynamic equilibrium in the inward-shifted vacuum configuration of the Large Helical Device. As the parallel thermal conductivity becomes larger, the perpendicular velocity of the linear eigenfunction becomes relatively smaller than the parallel velocity, and in the nonlinear phase, the energy of the perpendicular velocity is selectively damped by the viscosity. Consequently, the plasma is finally saturated with flattened pressure profile, finite parallel velocity, and fairly good magnetic flux surfaces.
