MICROPARTICLE SEPARATION IN A LINEAR PAUL TRAP
Abstract
We investigated the charged micron-sized particle separation by the alternating electric field in a linear quadrupole
electrodynamic trap in open air under standard atmospheric temperature and pressure conditions (STP). In experiments
we varied the amplitude of the alternating voltage supplying the electrodynamic trap and used a mixture of
charged glassy carbon and alumina particles. The carried out numerical simulations and experimental results showed
the mutual influence of the amplitude and frequency of the supplied to the trap electrode voltage on the separation
of the different sizes particles. The typical particle charges in simulations were approximately equal to experimentally
measured values obtained in a corona discharge.
