Laser Pulse GIF (IMAGE) DOE/Lawrence Berkeley National Laboratory Caption This 3D simulation shows a BELLA laser pulse interacting with a 50-nanometer-thick foil target. The laser pulse (from left) expels electrons (red) from the target. This causes strong magnetic fields that can accelerate ions (blue) in a what’s known as a Coulomb explosion. The simulation was created using the Berkeley Lab-led code WarpX at the National Energy Research Scientific Computing Center.
