【 摘 要 】

The formation of cryogenic colloid of charged particles in static magnetic traps was studied for the first time. We presented experimental results of formation of strongly correlated structures consisting of about 103particles. Ordered structures were formed by particles with a diameter of 30-60 microns with a charge up to 107e. Estimates of mean interparticle distance, dust particle charges, coupling parameter and Lindemann parameter, which turned out to be typical for strongly coupled crystalline or glass-like systems.
