The mark consists of a white hexagon surrounding a black interior hexagon containing an orange polygon shape outlined in gold. In the orange polygon are the letters "A" and "T", displayed in black, with a small black hexagon between them. Three overlapping ovals also appear in the color white, with gold trim, creating an image of an atomic orbit. A white circle trimmed in gold appears at the lower left corner of the orbital design. The black area outside of the white hexagon represents background and is not part of the mark.
