Abstract

An apparatus efficiently produces of particles from gas phase chemical reactions induced by a radiation beam. The apparatus includes a reaction chamber and an elongated reactant inlet, where the reaction chamber is configured to conform generally to the elongated shape of the reactant inlet. Shielding gas may be introduced to form a blanket of inert gas on both sides of the reactant stream. A feed back loop may be used to maintain the desired pressure within the reaction chamber.
