Figure 7. In situ visualization with Ascent and VTK-m of a staged laser-wakefield accelerator simulation run on Frontier with WarpX. Shown are the strong accelerating fields (red to blue) in the plasma stages (gray). Injected in this structure is an electron beam (green to orange) that is accelerated to the right to high energies.
