Particles and Fields Package Monthly Status Review (MSR) August 21, 2012

1. Particles and Fields Package Monthly Status Review (MSR) August 21, 2012 Dave Curtis, PFP PM

2. PFP I&T

3. Schedule Status 2.5 weeks margin to delivery to LM Package testing complete, instrument schedules mostly decoupled Deconflicted resources for Cal chambers, TVac chambers STATIC is the critical path

4. EVM (June report) We continue to make up schedule and are getting close to a cumulative SPI of 1. We should deliver on time unless we run into issues, but do not have much margin to deal with issues. We continue to run high on cost as we press to make up schedule, but should start to fall off in manpower in the next month or two. SPI / CPI June 2012

5. Accomplishments PFP instruments all integrated PFP self-compatibility complete PFP EMC testing complete Instruments starting on component testing STATIC FM ACC/MCP complete, ready to install More in instrument sections…

6. Ongoing Work STATIC, SEP, EUV Calibration Instrument Environments MAG EMI Filter fabrication, test @ GSFC FSW Build 3

7. PFP PER Status 7 RFAs 6 closed 1 submitted, pending waiver (fastener lock)

8. Issues EUV Temp sensor noise Fix implemented in EM harness and tested at EMC Fix incorporated in FM harness by SSL MAG Heater CE/CS issues Filter to be added to MAG heater circuit Implemented as a box attached to the outside of PFDPU PFDPU does not have to be opened. Will be separately tested and qualified and attached late in the flow Noise in Electra receive band May require LPW to be powered off during relay orbits – TBR. Minor EMC issues to be addressed by waiver

9. Top Risks

10. Risks List

11. PFP Mass Slight increase this month based on as-measured PFDPU increase LM is looking at if there is an impact Will increase again for the MAG heater filter

16. Requirements Verification Status • Not yet updated with EMC results

17. MAVEN PFP MAG Status August 2012 Jack Connerney, MAG Lead

18. MAG Status MAGs supported PFP package testing and self-compatibility with no issues MAG supported EMC testing CE and CS issues with MAG heater – insufficient filtering External filter being built to be mounted to PFDPU To be separately qualified Breadboard filter tested at GSFC, provided to SSL for additional testing to verify performance FM MAG sensors will support PFDPU thermal vac test Outside chamber, in shield cans

19. MAVEN PFP SWEA Status August 2012 Dave Mitchell, SWEA Lead

20. SWEA Status • Full chamber CPT performed July 18 following Suite I&T  Successful (see next slide) • Suite EMC successful (Aug 6-14) • SWEA recorded a grand total of 0 counts during all susceptibility tests • No detectable radiated emissions from SWEA • SWEA went to vibe on Friday (8/17) • Testing incomplete because of facilities issues • Plan is to complete vibe on Monday (8/20) • CPT to follow vibe • SWEA to begin Thermal Vac next • Bayside Tvac chamber is ready • GSE set up and ready (tested with EM) • Test procedures reviewed and revised. SWEA at Suite I&T

21. SWEA CPT on 18 July 2012

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

23. SWIA Progress • FM Assembly Complete • SWIAFMcompletelyintegratedwithPFDPU • EMCComplete • Environmental Testing and Calibration Proceeding Well • EMC passed with no issues for SWIA • Zero counts seen by SWIA during test • No anomalies in voltages, temperatures, etc. • Optics verification in vacuum chamber this week to make sure everything still nominal after recent attenuator replacement • Vibration test scheduled for Monday, Aug. 20 • Magnetics test planned for week of Aug. 20 • TVAC scheduled August 31 – September 9 (after SWEA) • Final calibration scheduled September 21-30 (after SWEA)

24. SWIA Issues • Schedule for rest of summer • TVAC chamber and calibration chamber both have tight schedules with SWEA, SWIA, and STATIC stacked up one after the other • Backup chambers exist for both tests but each have drawbacks • Will be watching schedule margin closely to see if we need to mitigate schedule risk by changing chambers • Flight software processing and telemetry • LUT loads and HV control all working now • Most processing and telemetry now working • Outstanding issue with accumulation buffer timing leads to first half of spectrum N and second half of spectrum N-1 being combined

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

26. STATIC Accomplishments FM STATIC successfully passes EMC – no noise detected. PFDPU successfully produces STATIC APIDs D8 and DA, as needed for EMC. FM ACC/MCP HVPS assembled, tested in high vacuum, ready for integration with the FM unit – last FM board complete. ACC/MCP HVPS board PFRs (PFRs 79,80,82,93 – closed; PRFs 95,97,106 complete, signoff pending) Digital board PFRs (PFR 55,57,66 – closed; PFR 70 signoff pending). Anode board PFRs (PFR 60,64,88 - closed) TDC board PFRs closed (PFR 58 - closed) LVPS board PFRs (PFR 51 - closed) FM spare aperture mechanism & mechanical attenuator subsystem assembled/tested/installed in STATIC FM unit, spare subsystem replaced damaged unit (PFR 102 - signoff pending). FM pin-hole attenuator fabbed/installed (PFR 100 - signoff pending) Spare anode HV connector fabricated/tested – allows spare Anode-MCP to be assembled.

27. STATIC Open Issues PFDPU not yet generating the bulk of STATIC APIDs Attenuator fix (PFR 100) needs testing during calibration (~8-27) FM spare mechanical attenuator and aperture mechanism need testing during vacuum calibration (PFR 102). Test scripts need to be modified into RTS commands New small ion gun for low energies (<10 eV) fabricated and in test. This will free up the old small ion gun for used in TV testing. New Colutron ion gun run -- ions detected with faraday cup. Still having problems with cooling the heat sink – not designed to operating in a hot calibration room. Colutron gun needs testing with EM sensor before calibrations with the FM sensor. Spare units for critical subsystems are now being assembled (ACC/MCP, MCP-Anode, TOF analyzer) STATIC begins calibrations 8-27.

28. MAVEN PFP SEP Status August, 2012 Davin Larson, SEP Lead David Glaser, SEP ME Miles Robinson, SEP EE

29. SEP Accomplishments Unfortunately SEP has had (two) serious mishaps. A STATIC safe-to-mate test resulted in the overstressing of the nano-muscles on both sensor units. (PFR-101) Repairs to the units were done hastily to be ready in time for EMC testing. A final safe-to-mate test was not done prior EMC, thus a nano-muscle that was damaged during cover closing was not detected. This resulted in short from ACTRET to ground. All four nano-muscles were over stressed a second time during EMC due to this short. (PFR 114) Nano-muscle are being replaced now. SEP completed EMC with a need for waiver. SEP noise during CS tests on actuator service Post EMC CPT successful (with exception of actuator) Calibration to begin following repairs (End of week/weekend/ next week) Vibe will be delayed until September. T/V should not be delayed. (Will follow LWP in SNOUT2)

32. PFDPU Flight System EMC Testing at MetLabs during first half of August MAG Heater CE/CS results => addition of EMI Filter GSFC is building the new filter box. SSL will provide mounting studs so the box can simply be bolted on without removing any hardware.

33. PFDPU Flight System Instrument Integrations completed prior to EMC Testing All CPTs have been run using the PFDPU DCB and Power Supply performance nominal throughout the EMI/EMC operation Interference issue discovered during EMI/EMC Testing First time assembly with flight harnesses & no connector savers One of the backshells could not be completely installed The affected shear panel has been machined and the part is now at Industrial Plating for surface treatment. Deintegration upon return from EMC Testing Instruments to proceed separately through TVAC and Vibration PFDPU Vibration scheduled for August 27th Minor touch-up pending for PFDPU Reinstallation of Shear Panels Cable Harnessing Support for Internal MDM Harness

34. GSEOS Status Support provided during PF Instrument Integration and Environmental Testing SSL Data hub created routes data from remote/local PFP testing to local/remote users During EMC testing, scientists located at SSL, LASP and GSFC were able to view their data in real-time

35. PFDPU Ongoing & Upcoming PFDU ETU System used for FSW Test/Development Goal is to keep all ETU instruments integrated ETU Instruments move in and out as they are required for instrument specific tests/calibrations PFDPU Magnetics scheduled for August 29/30 Preparation for PFDPU TVAC in process (scheduled for Sept) Specification of cabling to/from the SNOUT1 chamber & general logistics Qualification criteria and stimulus for the PFDPU based instrument electronics Stimulus and monitoring requirements for the outboard instrument
