From: Creation of two-dimensional Coulomb crystals of ions in oblate Paul traps for quantum simulations
Top view of the proposed oblate Paul trap. The ions are trapped in the through hole in the center, which is magnified in a three-dimensional image in panel (b). The diameter and height of the RF ring electrodes is 500 μm and 140 μm, respectively. Radial optical access tunnels are visible in (b) and will contribute to the breaking of rotational symmetry, but play no other role in this analysis. Electrodes 1-4 are labeled in both panels and the RF ring is shown in panel (b). The origin is defined to be at the center of the trap. For our calculations, we hold all four electrodes on either the top or bottom face at the same potential as the segmenting is for compensation of stray fields in the experiment and plays no role in the ion crystal structure.
