Linear electrodynamic trap as a tool for cleaning dusty surfaces

摘要

>This work is devoted to the experimental and numerical investigations of the possibility of cleaning dusty dielectric surfaces using an electrodynamic trap. We used a linear quadrupole Paul trap and polydisperse aluminium oxide particles in our experiments. Numerical simulations were performed using Brownian and molecular dynamic methods. The phenomenon of lifting and trapping of uncharged particles placed on the glass substrate located under the trap was experimentally observed. The parameters of the trap and charges of dust particles, which are necessary for drawing them from the substrate and confining in the trap, were also estimated using numerical simulations.
