| Description: |
False-color images of 1, 2, 3, 6, and 12 magnesium ions loaded into NIST's new planar ion trap. Red indicates areas of highest fluorescence, or the centers of the ions. As more ions are loaded in the trap, they squeeze closer together, until the 12-ion string falls into a zig-zag formation.
