Abstract
An apparatus for transporting charged particles. The apparatus includes a control unit and a transport device having a plurality of electrodes arranged around a transport channel, wherein the transport channel includes a bunch forming region configured to receive charged particles received by the transport device. The control unit is configured to control voltages applied to the electrodes to generate a transport potential in the transport channel, the transport potential having a plurality of potential wells which are configured to move so as to transport charged particles along the transport channel in one or more bunches. The control unit is further configured to control voltages applied to the electrodes: temporarily generate a gathering potential in the bunch forming region so that charged particles received by the transport device are gathered in the bunch forming region; and then generate the transport potential in the bunch forming region so that a selected potential well is formed in the bunch forming region with the selected potential well receiving a bunch of charged particles formed from the charged particles gathered in the bunch forming region by the gathering potential.
