Abstract

The James Webb Space Telescope (JWST) program was supported by a unique team of Contamination Control Technicians (CCTs) who received Webb specific training from Webb Contamination Control Engineers (CCEs) and Lead CCTs. Webb’s design featured exposed optics and thermal control surfaces. These remained susceptible to damage or degraded performance from particulate and molecular contamination if a systematic approach to controlling contamination generating processes was not strictly enforced. Cleanroom maintenance is typically performed by janitorial services throughout the industry. However, Webb’s requirements necessitated a team who safely and effectively performed various tasks including daily facility cleaning to flight hardware handling. The CCT team performed daily cleanings of the processing facilities and effortlessly switched to inspecting and cleaning flight hardware, assisting CCEs with inspections, lab work, and performing on-demand cleaning of all items entering the cleanroom facilities. The versatility of the CCT team was on display as each CCT took on additional responsibilities and maintained ownership of subtasks such as Image Analysis and Ellipsometry, transportation, Self-Contained Atmospheric Protection Ensemble (SCAPE) suit support, inventory, and cleanroom garment laundering, while supporting the demanding launch campaign. The CCTs maintained a constant presence on the integration floor, allowing for quick resolution to CC issues and elevation of more serious problems that required further guidance. These dedicated CCTs broke new ground in efficient collaborative work with the integration and testing team while cultivating positive attitudes towards contamination control.
