1 PFP MSR, 11/15/2011 Particles and Fields Package Monthly Status Review (MSR) November 15, 2011 Dave Curtis, PFP PM

2 PFP MSR, 11/15/2011 Schedule Status STATIC, SWIA on critical path –9.6 weeks margin to delivery to LM –Critical Path runs through electronics fab & test –Boards are starting to come out of PWB fab, getting ready to start loading at JPL (who is quoting better delivery times than other subcontractors) Holding PFP package integration date for now –April 2012 –SWIA/STATIC calibration will not be complete at that time, get completed after package I&T (which hurts delivery margin) –Note that STATIC takes the longest to qualify. If STATIC schedule deteriorates we could consider delivering that separately; the rest of the package has 12 weeks of margin Changed FSW Build 3 delivery from just before to just after PFP Environments –Gives more time to include any changes/fixes required based on package level testing

3 PFP MSR, 11/15/2011 Accomplishments EM progress: –All EM testing complete except: STATIC calibrations REG #2 testing FM Electronic Progress: –17 PFP flight PWB fabricated, 7 loaded and in test MAG MAD & ACHE boards, SWEA IRAP boards in test –9 boards in PWB fabrication –3 boards through review and in final adjustments before fab –3 boards still in final layout REG, STATIC LVPS, STATIC ACC/MCP FM Mechanical –LPW, SEP, MAG, SWEA, SWIA, STATIC mechanical parts all out to fab Most parts received and in assembly –PFDPU getting out to fab now Flight harness fabrication started, fit-checked on Spacecraft mock- up More in instrument sections…

23 PFP MSR, 11/15/2011 MAVEN PFP SWEA Status October 2011 Dave Mitchell, SWEA Lead

24 PFP MSR, 11/15/2011 SWEA Status - IRAP –FM calibration in progress –Azim/Elev response for upward deflections measured. –Azim/Elev response for downward deflections in progress. –Energy and UV responses scheduled for Nov Elevation = 0

25 PFP MSR, 11/15/2011 SWEA Status - SSL –FM Digital fab complete, coupons sent out for testing. –Part loading instructions & board level procedures complete –Flight design FPGA tested on EM (don’t expect any more changes prior to burning the flight part). –FM LVPC magnetic wind & test (in progress) –Board level procedures complete –EM LVPC integrated and tested in vacuum SWEA ETU Digital board installed into pedestal SSL pedestal (LVPS & Digital) IRAP analyzer IRAP front-end electronics

26 PFP MSR, 11/15/2011 SWEA Issues 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. For the SSL EM, top cap, deflectors, and outer hemisphere removed. Testing at IRAP shows that MAVEN FM does not exhibit this behavior. Testing planned for STEREO flight units. Vacuum tests repeated. Lower portion of SSL EM does not exhibit the charging behavior. Anomaly is associated with upper part of the sensor.
