The Aerogel Mesh Contamination Collector
Abstract
High performance optical and microelectronic components have ever tightening contamination specifications placed upon them. Contamination is now seen as a major reason for the degradation of space based optical systems and failure of high density integrated circuits used throughout industrial and military systems. To address this problem, contamination removal and collection techniques have been developed by Rome Laboratory (RL) However, some of these removal techniques create a flux of removed contaminants, which then may re- deposit on clean surfaces or be ejected into the environment. Current collection devices such as filters, charged metal plates or screens, and charged dielectric have collection efficiencies and capture radii incommensurate with the new nano- scale semiconductor devices and space optics system cleanliness requirements. Presented here is a new contamination collector (patent pending). The collector (Aerogel Mesh Contamination Collector) or AMCC, collects and contains particulate and molecular contaminants either passively or used in conjunction with contamination removal devices creating a synergistic contamination control system with prevention, removal, and collection capabilities. The system is applicable to both clean room and cryogenic-vacuum conditions such as spacecraft environments.
