19. 19 PFP QSR, 10/18/2011 SWEA Issues Short in inner toroidal grid of SSL EM Short located and repaired Electrical connections for all sensor surfaces tested and found to be correct: V0: top cap, inner toroidal grid, outer hemisphere, exit grid Ground: outer hemisphere, case Deflector voltages: upper and lower deflectors Analyzer voltage: inner hemisphere Further investigation of charging anomaly Both SSL and IRAP EM’s exhibit the charging anomaly. For the SSL EM, Nuflon removed from the top cap and then the entire part was plated with gold. Tests were repeated, and the same charging anomaly was observed. Testing at IRAP shows that MAVEN FM does not exhibit this behavior. Further testing of SSL EM will planned for week of 10/24 (repeat vacuum chamber tests on EM with the top cap assembly, outer hemisphere, and deflectors removed  isolate location of the issue)
