DEVICE FOR MANIPULATING CHARGED PARTICLES
First Claim
1. A device for manipulating charged particles, the device comprisinga series of electrodes located so as to form a channel for transportation of the charged particles;
- a power supply unit adapted to provide supply voltages to said electrodes so as to create a non-uniform high-frequency electric field within said channel, the pseudopotential of said field having one or more local maxima along the length of said channel, at least within a certain interval of time, wherein at least one of said maxima of the pseudopotential is transposed with time, at least within a certain interval of time and at least within a part of the length of the channel, wherein the supply voltages are high-frequency voltages synthesised using a digital method.

Abstract
The present invention is concerned with a device for charged particle transportation and manipulation. Embodiments provide a capability of combining positively and negatively charged particles in a single transported packet. Embodiments contain an aggregate of electrodes arranged to form a channel for transportation of charged particles, as well as a source of power supply that provides supply voltage to be applied to the electrodes, the voltage to ensure creation, inside the said channel, of a non-uniform high-frequency electric field, the pseudopotential of which field has one or more local extrema along the length of the channel used for charged particle transportation, at least, within a certain interval of time, whereas, at least one of the said extrema of the pseudopotential is transposed with time, at least within a certain interval of time, at least within a part of the length of the channel used for charged particle transportation.
