2-D Crystal Lattice

2-D Crystal Lattice

Part of a 2-D crystal lattice containing 300 trapped beryllium ions and viewed using fluorescence at 313 nm in an ion crystal, which is spinning at 43.800 kHz. The ion separation of 20 mm is a balance between trapping forces and Coulomb repulsion. The lattice is being studied for quantum simulations.
