Simulation in the Laboratory Frame (IMAGE)
Caption
A simulation of laser-plasma acceleration in the laboratory frame. The wavefronts of laser light are the red and blue disks at right; the fields in the wake are colored from pale blue (accelerating) to orange (decelerating). Electrons accelerated by the first of many buckets in the wake are shown in white at right. Both the laser and the wakefield buckets must be resolved over the entire domain of the plasma, requiring many cells and many time steps. Researchers often use a simulation window that moves with the pulse, but this is not a true transformation of frame and reduces only the multitude of cells, not the multitude of time steps.
