Abstract
We consider the effective potential in a linear Paul trap with an asymmetrical power supply system. Only the DC voltage component is applied to the one pair of rod electrodes, and only the AC component is applied to the other pair. We propose an analytical description of the effective potential for an asymmetrical power supply scheme. Mathematical simulation shows the effective potential splitting along the axis of the trap. To confirm the proposed description, we perform an experimental localization of starch microparticles with an asymmetrical power supply system. The charged microparticles localization area splitting into two spatially separated areas along the trap axis is shown.
