Schematic diagram of our proposed electrostatic trap. The two electrodes are the same in geometry and shaped in the following way: a 20-mm-in-diameter and 8-mm-in-height cylinder electrode is first subtracted by part of a 12-mm-in-radius ball and then drilled through by an 8-mm-in-diameter hole in the center. The two pieces are placed with a face-to-face distance of 32 mm in the center. The molecular beam is incident along the z axis.
