A ''dust beam'' is created by a gas-particle mixture flowing through a capillary into vacuum. In a laminar flow, the viscous drag accelerates the particles in the direction of the gas flow, while the Bernoulli force concentrates them near the axis of the tube. At the exist of the tube the gas diffuses, but the particles, due to their inertia, continue with small divergence. This property will allow us to differentially pump the carrier gas along the dust beam axis before the microparticles enter the high vacuum of the storage ring.
