Bakeout Workshop
Spacecraft hardware thermal vacuum exposures and bakeouts have been used for years to reduce molecular outgassing to limit contamination to critical optics and sensors on-ground and in orbit. This presentation will discuss lessons learned and vacuum procedural techniques to make the most of your vacuum time. Quartz Crystal Microbalances (QCMs) and Residue Gas Analyzers (RGA) are 2 devices that help track molecular outgassing and examples will be shown on how to use them for your analytical benefit.
