Figure 1 (IMAGE) American Physical Society Caption Overview schematic of a tokamak highlighting exhaust into the divertor region. The zoomed in region shows the narrow geometry of the divertor and the camera view from the experiments. Images from the experiments show that heat fluxes decreased during p powder injection, indicating the reduced heat fluxes during powder injection. Credit F.
