2. FIELDS Phase B Risks Mitigation • FIELDS Risk Mitigation activities for Phase B include: • Antenna Qualification: • Nb materials testing, optical props aging (~Feb to Apr ‘12 TBR(was 3/12), MSFC or EMTL(was Odeillo, France)) • Antenna model thermal testing (~Oct ‘12 to Jan ‘13 (was 3/13), Odeillo, France) • Additional contingency test, if needed (~Oct ‘13, Odeillo, France) • SCM / MAG / FGM Trade: • Determine the optimal technical (dynamic range) & resource (mass and thermal) solution (close by 4/12) • See Trades Slide for additional information. • MAG Performance Over Temperature: • MAG Cold Operations Test (~1/13) • MAG Thermal Cycling Test (end of Phase B) • MAG/SCM Interference: • MAG/SCM Interference test (similar to the MAG/FGM test performed in 7/11) (~5/12 TBR (was 4/13), Chambon, France) • Blue = change since MDR
