A Dark Matter Flash

Caption

When a WIMP collides with a xenon atom, the xenon atom emits a flash of light and electrons. The light is detected at the top and bottom of the liquid xenon chamber. An electric field drifts the electrons to the top of the chamber, where they generate a second flash of light.
