Scientific paper

Electrostatic accelerators are successfully used for simulation of effect of micrometeoroid and space debris small particle impact on spacecraft materials and equipment in ground-based experiments. In such experiments, metal particles (size is 0.5-10 micrometers) which are electrically charged previously are usually accelerated. In the present work, the possibility of electrostatic acceleration of liquid microparticles was investigated. It is possible principally to achieve the higher value of the q/m ratio (q and m are particle charge and mass accordingly) for liquid microparticles than for solid ones that enables to reach the higher particle velocity. Besides, the accelerated drops may have identical sizes that is important for the solution of some scientific and applied problems. In the paper, design of the liquid microparticles electrostatic accelerator laboratory prototype is described, and test results are presented.
