Performing Accurate Multi-Paction Measurements

Multi-paction effects can impact microwave components in high-power satellite communications (sat-com) systems. The nonlinear break-down-voltage phenomenon occurs in high-vacuum environments above a certain threshold voltage, and can degrade the performance of RF and microwave components or, in extreme cases, damage the components or the system. Although multi-paction effects are often difficult to predict and measure, properly equipped test systems with dedicated software can accurately ...

Identifying Environmentally Friendly Coatings that Protect in Harsh Environments

By Chuck Griffin, Kennedy Space Center, Florida

NASA coats metallic structures and ground support equipment to guard against the adverse effects of corrosion and to ensure they meet or exceed intended performance life. These coatings include inorganic zinc coatings, primer and/or intermediate coatings, finish coatings, and epoxy mastic coatings, among others. In recent years, commercial coating products have changed due to new formulations, changing product ...
