  1. The minimum-B trap depth at various times, the change in the gravitational potential energy going from the top (y=+RWall) to the bottom (y=−RWall) of the trap, and the polarization potential energies. The ‘Gap’ polarization potential energy is the energy gained entering the gap between the electrodes, and the ‘Patch’ potential energy is the energy gained approaching a typical patch field region on the electrodes17.
