A scheme for forming a Coulomb lattice of positively charged dust grains in a high-pressure (P > torr) gas is discussed theoretically. The grains are charged positively by photoemission in the presence of a flux of ultraviolet (UV) photons with energy larger than the work function of the grains, but lower than the ionization potential of the background gas. Methods for levitating and confining the dust using photophoretic forces (both UV and non-UV), gas drag, and electrostatic forces are considered.
