To do so, the x-ray detector had to take pictures at a relatively low resolution of 30 pixels, which produced images on a crude, hexagonal grid-as shown in the chart below.

The box is lined with lead to shield the x-ray detector from stray radiation. The resulting 1,500-pound (680-kilogram) camera-created by Dwyer's graduate student Meagan Schaal-consists of an x-ray detector housed in a box about the size and shape of a refrigerator. "You can't just go buy a camera and point it at lightning," he said. Making a camera capable of taking such quick images was an achievement in and of itself, Dwyer emphasized.
