The analysis of dusty plasma properties at cryogenic temperatures shows that it is necessary to take into account the condensation of helium on the plasma particles. The micron particles in the saturated helium vapor are covered by a liquid helium film of 100 Å thick. This leads to the limitation of electron charge of the particles, as the electrons can hardly penetrate such a
film. The exceptions are Cs, Rb and K clusters as they are not wetted with helium.
