“…To use either of these experimental setups to investigate beam dynamics under conditions of more intricate lattice configurations, novel diagnostic techniques have to be devised and tested for Paul traps. Such a technique is demonstrated in [628], where a new method is described to measure the beta function and the emittance at a given time in a Paul trap. A novel technique is also demonstrated in [629], where direct measurement of low-order coherent oscillation modes in a LPT is performed by detecting the image currents induced on the electrodes surfaces.…”

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.
