Topics • Build Plan and Status • Performance Verification Plan and Status • Contamination Control • Assembly, Integratin, and Test/Flow • Facilities
Contamination Control • All materials were selected to meet NASA low-ougassing requirements (1% TML, 0.1 CVCM). • After Painting the BB will be baked out in a vacuum at SDL and returned to UW for completion of assembly and testing. • Blackbody will be assembled on a Class 1000 laminar flow bench and will be double-bagged. • Prior to installation of the internal MLI at SDL, the BB will be cleaned with a CO2 Snow Cleaning process (except for the internal painted cavity surface). • Following MLI Installation the BB double bagged and purged with dry N2 during any temperature testing. • The Controller Board will be cleaned at SDL, prior to the Conformal Coating Process. • After Conformal Coating at SDL, the Board will be stored in ESD bags. (during any temperature tests, it will be purged with dry N2)
