Adding just enough fuel to the fire
Princeton Plasma Physics LaboratoryPPPL researchers have determined the maximum density of uncharged particles at the edge of a plasma before certain instabilities become unpredictable. This is the first time such a level has been established for Lithium Tokamak Experiment-Beta. Knowing this level is a big step in their mission to prove lithium is the ideal choice for an inner-wall coating in a tokamak because it guides them toward the best practices for fueling their plasmas.
