Fluid/Kinetic Modeling of ITER Plasmas

The International Thermonuclear Experimental Reactor (ITER), which is scheduled for deuterium-tritium plasma shots in 2035, will produce up to 500 MW of fusion power.  Fusion byproduct alpha particles will represent a substantial fraction (~ 30%) of the ions in ITER plasmas.  This poses a challenge for existing plasma simulation codes which typically assume low number density for the energetic particle (alpha) component.  This talk will focus on the development of consistent fluid/kinetic models that allow for a large population of fusion alphas in addition to the thermal electron and ion distributions.
