Dust Particles Behavior in an Electrodynamic Trap

Dust Particles Behavior in an Electrodynamic Trap

The behavior of the charged dust particles in the linear Paul trap was simulated by Brownian dynamics for reasonable choice of the particle parameters and trap electrode voltages. Regions of these parameters needed for particle confinement at normal atmosphere conditions (pressure and temperatures)...

Zusammenfassung:The behavior of the charged dust particles in the linear Paul trap was simulated by Brownian dynamics for reasonable choice of the particle parameters and trap electrode voltages. Regions of these parameters needed for particle confinement at normal atmosphere conditions (pressure and temperatures) have been obtained. An influence of air viscosity, particle masses and charges, frequency and alternating voltage on regions of confinement were investigated. Obtained regions of the particle confinement agree with our experimental results for linear Paul trap. (© 2013 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
