Abstract :
An electrodynamic screen was designed, built, and tested for the removal of particles from its surface. The technology has a large number of applications ranging from space exploration to biotechnology. An AC signal was applied to the shield and it was studied the effect of its amplitude, shape, and frequency to the shield´s particle removal properties. The best working conditions were found to be: the amplitude ranging from 7 to 10 kV, and the frequency ranging from 5 to 15 Hz. The shield was proved to remove also the initially uncharged particles and to separate the particles based on their charge polarities.
