NSTX Heat Flux Analysis – Nathan Gardner – 2011

Nathan Gardner (2011 Physics graduate) spent a summer at the Princeton Plasma Physics Laboratory (PPPL) and worked on some calculations involving heat fluxes in the National Spherical Torus Experiment (NSTX).  .  The NSTX is an experimental fusion reactor at PPPL; spherical torus refers to the shape of the fusion reaction chamber, a shape which allows for a lower input power than any other tested shape for starting fusion reactions.  The heat fluxes need to be studied for a better understanding of how the plasma interacts with and affects the inner parts of the device so future reactors can better control the heat fluxes and utilize more resistant materials in the device.  Nathan’s work involved calibrating the IR cameras used, and analyzing the real world data and compare to simulations for future predictive power.   Advisor: Dr. Valentina Tobos (vtobos@ltu.edu).
