Three-dimensional electrostatic trap. a Schematic diagram of a single-stage Rydberg-Stark decelerator and three-dimensional electrostatic trap. b and (c) electric field distributions in the yz and xz planes at the center of the trap with potentials of |V _1,2,3,4|=20 V and |V _5,6|=55 V. The contour lines are spaced by 10 V/cm with the center-most corresponding to a field of 20 V/cm. The color bar indicating the field strength in (c) also holds for (b). From [118]
