Abstract:
A particle production system comprising:a particle synthesis apparatus comprising:a reaction chamber isolated from the ambient atmosphere, the reaction chamber comprising gas and the reaction chamber having a reactant inlet for supplying reactant into the reaction chamber and a product outlet from which the product particles exit the reaction chamber, wherein the gas in the reaction chamber is at a pressure less than about 700 Torr; anda particle collection apparatus comprising:a collection chamber having a collector inlet, a gas outlet, and a particle drain, wherein the gas outlet is connected to a pump that vents to the atmosphere;a plurality of filters within the collection chamber such that the filters obstructs flow paths from the collector inlet to the gas outlet and such that particles dislodged from the filters flow to the particle drain; anda particle removal system that applies forces to the filters to dislodge particles from the filters;wherein the product outlet of the particle synthesis apparatus is in fluid communication with the collector inlet of the particle collection apparatus.
