Division Spotlight
Aerospace Nuclear Science & Technology
Organized to promote the advancement of knowledge in the use of nuclear science and technologies in the aerospace application. Specialized nuclear-based technologies and applications are needed to advance the state-of-the-art in aerospace design, engineering and operations to explore planetary bodies in our solar system and beyond, plus enhance the safety of air travel, especially high speed air travel. Areas of interest will include but are not limited to the creation of nuclear-based power and propulsion systems, multifunctional materials to protect humans and electronic components from atmospheric, space, and nuclear power system radiation, human factor strategies for the safety and reliable operation of nuclear power and propulsion plants by non-specialized personnel and more.

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.

Using circuit theory and solutions of a scalar two-dimensional Laplace equation for the electrostatic potential, we examine various feedthroughs of interest for voltage holding, voltage standing wave ratio (VSWR) and impedance characteristics. Suitable inhomogeneous Dirichlet, scalar boundary conditions are imposed for the potentials for the calculation of the electrostatic fields. The inhomogeneous vector Newman boundary conditions on the surface of the dielectric are dispatched by use of a conformal mapping. Several feedthroughs are examined: old Princeton Large Torus (PLT), JÜLICH designs, and several Oak Ridge National Laboratory (ORNL) designs that have been actually fabricated and exhaustively tested. Some of these feedthrough configurations have been optimized to provide constant 50-Ω impedance or minimum VSWR.
