Device for manipulating charged particles
First Claim
1. A device for manipulating charged particles, the device comprising:
- a series of electrodes arranged so as to form a channel for transportation of the charged particles, the series of electrodes being adjacent to one another along a length of the channel;
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 two or more local maxima along the length of said channel for transportation of charged particles, at least within a certain interval of time, wherein transportation of the charged particles along the length of the channel is provided by transposition of the at least two of said maxima of the pseudopotential such that the at least two of said maxima are caused to travel with time along the channel, 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;
wherein the channel is filled with a buffer gas and the pressure of the buffer gas varies along the length of the channel, so that injection of charged particles into the device at an inlet of the device takes place at a higher pressure as compared with an outlet of the device;
wherein the device is configured to transport the charged particles to a low pressure region of the channel in which the pressure is less than 5×
10−
3 mbar;
wherein in the process of transportation of the charged particles, equalisation of kinetic energies of charged particles occurs due to collisions and energy exchange between charged particles and buffer gas molecules.

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.
