A macroscopic Coulomb ordered structure of polydisperse СеОг particles in a laminar spray of weakly ionized thermal plasma under atmospheric pressure and temperature of about 1700 К has been experimentally observed. Diagnostic instruments allowed one to measure plasma parameters. The particles are charged positively and have of about ΙΟ3 electron charges. The calculated values of Coulomb coupling parameter 7P is > 120 that corresponds to a strongly coupled plasma.
