Experimental evidence of the dust particles detachment possibility in the E-field

摘要

One of the complicating factors of the future robotic and human lunar missions, as well as the missions to atmosphere-less bodies, is the influence of the dust. Due to the solar wind and ultraviolet irradiation influence, the regolith of theatmosphereless body can obtain significant charge and therefore can produce strong electric fields above the surface. Theelectric field influences the surface dust particles and can become a trigger for the charged dust particles to detach fromthe surface under the Coulomb force influence. This study demonstrates the possibility of dust particles’ detachment understrong electric field conditions. The main goal of this work is to simulate the dynamics of charged dust particles in theexperimental vacuum chamber with the influence of the electric field with predicted values.
