【 摘 要 】

The microparticle dynamics in linear electrodynamic trap with different numbers of electrodes (8, 12 and 16) was theoretically studied. The regions of particle confinement as the dependencies of frequency of alternating voltage on particle charges and number of electrodes were determined. Amplitudes of particle oscillations decreases with the growth of the frequency as well as with the growth of the number of trap electrodes.
