Charged (nano)particles confined in electrodynamic traps can evolve into strongly correlated Coulomb systems, which are the subject of current investigation. Exciting physical phenomena associated to Coulomb systems have been reported such as autowave generation, phase transitions, system self-locking at the ends of the linear Paul trap, self-organization in layers, or pattern formation and scaling. The dynamics of ordered structures consisting of highly nonideal similarly charged nanoparticles, with coupling parameter of the order Γ = 10 8 is investigated. This approach enables us to study the interaction of nanoparticle structures in presence and in absence of the neutralizing plasma background, as well as to investigate various types of phenomena and physical forces these structures experience. Applications of electrodynamic levitation for mass spectrometry, including containment and study of single aerosols and nanoparticles are reviewed, with an emphasis on state of the art experiments and techniques, as well as future trends. Late experimental data suggest that inelastic scattering can be successfully applied to the detection of biological particles such as pollen, bacteria, aerosols, traces of explosives or synthetic polymers.

“…4 This kind of trap with hyperbolic geometry has a simple mathematical formalism, for which the dynamical behavior of ions can be properly described by the well-known Mathieu differential equations. [7][8][9] As a main disadvantage of a Paul trap, one can indicate the difficulty of its construction due to the hyperbolic shape of the electrodes. 10 Another disadvantage of a practical Paul trap can be attributed to the appearance of multipole electric field components caused by truncation of the hyperbolic-shaped electrodes.…”

“…[13][14][15][16][17][18] For instance, one of the recent studies has proposed a novel radio-frequency ion trap with spherical geometry. 7 In this article, in order to design a cylindrical ion trap (CIT), which behaves very similar to a pure QIT, a specific diameter to height ratio has been computed.…”

The cylindrical ion trap is analyzed so that the octupole component of the electric field inside the trap is set to zero. As a consequence, the diameter to height ratio is computed to be 1.20 for which the quadrupole component of the cylindrical ion trap is dominant. Afterwards, it is concluded that the electric potential inside the trap as well as the corresponding stability regions are very similar to those obtained for an ideal Paul trap with pure quadrupole electric field. Furthermore, we drew a conclusion that the stability diagrams of the cylindrical ion trap without octupole term and the stability diagrams of the Paul trap have 5.6%, 3.7%, and 2.9% discrepancy for the first, second, and third stability diagrams, respectively. It should be noted that, expansion of the electric potential inside the cylindrical ion trap in terms of the multipole electric field components and making the advantages of the octupole term elimination has not been reported in the literature previously.
