1. Particles and Fields Package Quarterly Status Review (QSR) October 9, 2012 Dave Curtis, PFP PM

2. PFP I&T

3. Schedule Status Recent developments have caused a slip in the PFP delivery to LM from 11/13 to 11/26 LPW thermal vac anomaly led to an FRB decision to remove the LPW boards from the PFDPU for diagnostics SWEA failure led to an FRB decision to open the SWEA analyzer for inspection (requires IRAP participation) PFDPU reintegration and test is the critical path to delivery If SWEA falls behind further it can deliver later, but nothing can deliver without PFDPU

4. Schedule

5. EVM (August report) SPI (and CPI) dropped a bit as we eat into the last of the pre-ship schedule margin. CPI remains low due to high manpower levels required to overcome problems and press to maintain delivery schedule SPI / CPI August 2012

6. Accomplishments LPW preamps completed thermal vac SWIA completed post-environmental calibrations PFDPU, SEP, LPW, MAG, EUV completed environments Except magnetics screening STATIC modified to fix noise problem associated with field emissions from the start foils SWEA HVPS problem fixed; SWEA preamps rebuilt; diagnostics continue to reduce risk of future high voltage discharges (working with FRB) More in instrument sections…

7. Ongoing Work Complete SWEA diagnostics, environments Complete STATIC calibration & environments Complete LPW diagnostics @ LASP Complete flight software acceptance tests MAG EMI Filter fabrication, test @ GSFC

8. Issues [1] EUV Temp sensor noise Fix implemented in EM harness and tested at EMC Fix incorporated in FM harness by SSL, but not as good as EM harness Additional improvement identified, being incorporated into FM harness Thermal test with fixed harness, FM PFDPU/EUV planned MAG Heater CE/CS issues Filter to be added to MAG heater circuit Implemented as a box attached to the outside of PFDPU Will be separately tested and qualified and attached late in the flow Breadboard filter tested with EM PFDPU Clean for Emissions, 6x better for susceptibility

9. Issues [2] SWEA HVPS problem in TVac HV discharge damaged one preamp Replacement preamp board complete Identified HVPS problem (broken multiplier) Diagnostics in progress to identify root cause STATIC Issues in Calibration HV field emission problem causes noise instrument New fix implemented – see STATIC section LPW (PFDPU) Thermal Vac Cold One LPW charge pump failed when cold at 2MHz Works at 1MHz, meets science requirements Concern that unknown cause risks LPW science FRB/Project decision to open PFDPU to diagnose problem LPW boards returned to LASP

18. MAVEN PFP MAG Status October 2012 Jack Connerney, MAG Lead

19. GSFC MAVEN MAG – Status MAG FM1 and FM2 performed as expected during PFP system environmental tests Elevated noise observed at times during the tests traced to grounding and other issues specific to non-flight like test configuration. Awaiting MAG test data exercising all PFP MAG-related functions for test and verification of PFP on board software. • Filter Box Schedule (filter box assembly delayed ~2-3 weeks by various contract issues). • Complete board receipt, inspection, checkout by 10/4/12. • Complete thermal tests of assemblies, ship to SAIC for coat and stake by 10/11/12; expect return of boards by 10/19/12. • Install boards in enclosure, checkout, complete by 10/24/12. • Thermal cycling, 200 hours burn-in to be completed by 11/02/12.. . • Schedule availability of filter boxes by 11/05/12.

20. MAVEN PFP SWEA Status October 2012 Dave Mitchell, SWEA Lead

21. SWEA Status SWEA was in thermal vacuum tests when it had a high voltage discharge that damaged a preamp Similar to a discharge we had in calibration which was blamed on a HV capacitor Also saw significant high voltage ripple (70Vp-p) On opening the instrument for diagnostics saw damage to diodes on the anode board Solder plating of leads flaking off, tiny flecks of solder on anode Concern that flecks could have gotten into analyzer Replaced diodes with surface mount parts Also found VMI HV multiplier on HV board was damaged Have not been able to remove multiplier for failure analysis – epoxied to PWB Added new multiplier, fixed ripple FRB decision to open analyzer to inspect for damage and contamination IRAP team coming to SSL to do the work next week

22. MAVEN PFP SWIA Status October 2012 Jasper Halekas, SWIA Lead

23. SWIA Progress • EMCPassed • Vibe Passed • T-Vac Passed • Final Calibration Completed • All SWIA Level 3 Requirements Met (Or Exceeded) • ATLO/Transition Scripts, LUTs, and RTSs delivered • Environmental Testing Nearly Complete: • Magnetics is the only environmental test remaining • ~235 hours of power-on time for full FM to date • ~100 w/ HV

24. SWIA Issues • Flight MLI thermal blanket may need to be slightly altered to accommodate all connectors on doghouse • Connectors come in from two directions • Hole in MLI blanket not quite big enough to accommodate • Plan to do test-fit with flight cable to determine best way to alter blankets • Radiator area may also need to be adjusted.

25. MAVEN PFP STATIC Status October 2012 Jim McFadden, STATIC Lead

26. STATIC Accomplishments FM TDC board modified (PFR 120), tested in vacuum – works properly. FM aperture mechanism tested in vacuum – works properly. During re-testing of the STATIC FM sensor, after the TDC fix, a new source of noise was identified. This noise is different from the low level noise that initially generated PFR 119, and will be added to that PFR. The noise appears to be associated with small tears in the Start carbon foils resulting in field emissions ~100 nA, much larger than previous background emissions. Contact with the UNH Cluster/CODIF team identified similar problems that could develop after weeks of operation. Suppressing this emission requires adding a grid in front of the foil – similar to the suppression grid on the Stop foils. The grid and spacer were fabricated, grid electro-polished, and installed this week. Static went under vacuum by Oct. 5 and calibrations should start Oct. 8. FSW for generating all STATIC APIDs developed - in test. Ground software for decommutating STATIC APIDs developed - in test. Ground software for MLUT table generation completed - in test Ground software for RTS commands generation completed - in test.

27. STATIC Open Issues / Tasks Start carbon foil suppression grid needs testing to verify it eliminates field emission noise identified in earlier tests. STATIC needs to complete environmental tests after calibrations. STATIC APIDs and RTS commands generated by PFDPU need thorough testing on the EM and FM units. Colutron ion gun Wein filter repaired (broken internal wire) but gun is still having heat dissipation problems – can’t be run on hot days. Colutron gun needs testing with EM sensor before calibrations with the FM sensor. Spare units for subsystems (ACC/MCP, MCP-Anode, TOF analyzer) are waiting for a break in ME work load for assembly.
