1. 1 PFP MSR, 9/18/2012 Particles and Fields Package Monthly Status Review (MSR) September 18, 2012 Dave Curtis, PFP PM

2. 2 PFP MSR, 9/18/2012 Schedule Status 1.5 weeks margin to delivery to LM –Per 9/1 Schedule –As of 9/17 it looks more like 1 week Instruments in various stages of environmental testing Various problems found during test have eaten into margin and also distracted instrument leads from support needed by software developer to finish flight software. STATIC and FSW are the critical path –FSW plan includes deadlines and work-arounds which are likely to involve a Build 4 delivered after ATLO. –Depending on developments, STATIC may push ahead of SWEA, putting SWEA on critical path

3. 3 PFP MSR, 9/18/2012 Schedule

4. 4 PFP MSR, 9/18/2012 EVM (July report) We continue to make up schedule and are effectively at a cumulative SPI of 1. We continue to run high on cost as we press to make up schedule, and manpower is dropping off more slowly than planned. This is also partially due to extra work added to resolve issues found during testing which was not budgeted for. SPI / CPI July 2012

5. 5 PFP MSR, 9/18/2012 Accomplishments LPW booms through thermal vac with associated hot and cold deployments SEP, PFDPU, SWEA, and SWIA passed vibration –SWEA had HV issues in TVac possibly related to vibration SEP, SWIA, and PFDPU in Thermal Vacuum STATIC issues resolved, back in calibration EUV Calibration complete More in instrument sections…

20. 20 PFP MSR, 9/18/2012 MAVEN PFP SWEA Status September 2012 Dave Mitchell, SWEA Lead

21. 21 PFP MSR, 9/18/2012 SWEA Status –SWEA vibe (8/17, 8/20) –Instrument passed vibe on 8/20 and went into Thermal Vac that afternoon. –SWEA to Thermal Vac (8/20 – 8/25) –Instrument completed hot/cold survival and thermal balance, then 2 low voltage operational cycles –1-time cover actuator failed on side B because of a short on the digital board (PFR 116) –Digital board repaired and bench tested –SWEA back to Thermal Vac (8/30 – 9/1) –Instrument repeated survival cycle –Cover opening successful on side B (Cycle 4) –Instrument experienced issues with HV in Cycle 5 (next page). Actuator B Short Locations

22. 22 PFP MSR, 9/18/2012 SWEA Anomalies –SWEA Thermal Vac, Cycle 5 (9/1) –After 36 hours at high vacuum (12 hours since cover opening), a CPT including HV was performed –NR enable OK. Several small transients observed during MCP ramp-up. An arcing event occurred at 2500 V, resulting in the loss of preamp 14. (PFR 59, continued) –Diagnostics and Testing (9/2 – present) –After extensive testing in the chamber, then disassembly, inspection, and testing on the bench, three issues were discovered: 1.The HV board has an intermittent noisy mode that was not observed prior to vibe/Tvac 2.Tinning on the leads of vertically standing diodes on the Anode board was cracking and peeling (not observed prior to vibe and Tvac) 3. Holes in the Anode board (used for alignment posts during assembly) were not covered. Possible contamination risk.

23. 23 PFP MSR, 9/18/2012 SWEA Anomalies – Path Forward –Entirely new Preamp board has been built up using spare PCB and passive parts from IRAP, 16 new A111F preamps from MMS, and an new 4040 from SSL stock. New board is ready for test. –HV Board Intermittent Noise –Bench testing Monday-Tuesday, comparing FM and EM to identify source of the noise –Repair plan pending test results –Cracked tinning on diode leads –Two diodes were removed from the spare Anode board, and replaced with surface mount equivalents –This approach looks promising, and if it passes FRB review, we’ll adopt this approach. Otherwise we’ll increase the bend radius of the leads on vertically mounted diodes. –Holes on the Anode board –Holes will be covered with kapton tape during diode repair –PEEK covers will be staked over the holes before final assembly.

24. 24 PFP MSR, 9/18/2012 MAVEN PFP SWIA Status September 2012 Jasper Halekas, SWIA Lead

25. 25 PFP MSR, 9/18/2012 SWIA Progress EMC Passed 118 hours of power-on time for full FM to date (~40 w/ HV) Expect several hundred more in T-VAC and calibration Flight software for SWIA now has most issues ironed out Major Issues with Vibe Three consecutive vibration test failures Instrument (including HV) was still fully functional after first two failures BREAKING NEWS. SWIA Passed vibration 9/14, headed to TVac SWIA now in Thermal Vacuum

26. 26 PFP MSR, 9/18/2012 MAVEN PFP STATIC Status September 2012 Jim McFadden, STATIC Lead

27. 27 PFP MSR, 9/18/2012 STATIC Accomplishments FM pin-hole attenuator (PFR 100 – signoff pending) tested during calibrations. FM spare aperture mechanism & mechanical attenuator subsystem (PFR 102 - signoff pending) tested in cal chamber with harness. New small ion gun for low energies (<10 eV) fabricated & tested. Spare FM Anode board completed. Re-testing STATIC FM sensor (PFR 119) helped identify a source of noise that could appear after several days of operation. Testing allowed development of a procedure that eliminates the noise: Running the ACC at full voltage with MCPs off to maximize TOF field burns off sub-visual surface features that produce noise through field emission. FM ACC/MCP re-tested (PFR 119) with spare HV connector – no problems with HV supply. Problems with FM TDC board identified (PFR 120) and a fix applied to the EM board was tested.

28. 28 PFP MSR, 9/18/2012 STATIC Open Issues Noise due to field emission in the TOF analyzer was identified during calibrations (PFR 119). The suspected sources were the recently completed FM ACC/MCP supply and/or dust introduced during assembly. ACC/MCP supply was retested - worked nominally. The sensor head was opened and inspected - no visible contamination. Sensor reassembled and tested – no noise was detected after 2 days pumping. Sensor retested every day for the following week. A similar field emission noise source appeared on 6 th day and increased with sensor operations. We found that the noise could be eliminated by turning off MCP detectors and setting ACC to maximum for several hours. The noise would initially increase, then completely dissappear. Noise seems to be caused by sub-visual surface features that burn off when field emission is maximized. A TDC board timing problem (PFR 120) is currently being implemented on FM TDC. DONE STATIC needs final assembly after TDC fix before calibrations can resume. Anticipated restart of calibrations is 9-17. STARTED

29. 29 PFP MSR, 9/18/2012 STATIC Open Issues PFDPU not yet generating the bulk of STATIC APIDs –Delayed for lack of EM STATIC to test it on; EM in use for diagnosing hardware issues; should now return to FSW test system FM spare mechanical attenuator and aperture mechanism need testing during vacuum calibration (PFR 102). Test scripts need to be modified into RTS commands for PFDPU. New Colutron ion gun Wein filter did not work (broken internal wire) – sent back to manufacturer for repairs. Colutron gun needs testing with EM sensor before calibrations with the FM sensor. Spare units for critical subsystems are being assembled (ACC/MCP, MCP-Anode, TOF analyzer)
