Particles and Fields Package Quarterly Status Review (QSR) January 18, 2012 Dave Curtis, PFP PM
Schedule Status STATIC on critical path 7.2 weeks margin to delivery to LM Critical Path runs through electronics fab & test PFP package integration start date shifted ~1+ weeks Late April 2012 SWIA/STATIC calibration will not be complete at that time, get completed after package I&T Note that STATIC takes the longest to qualify. If STATIC schedule deteriorates we could consider delivering that separately; the rest of the package has 9.4 weeks of margin We have 2 weeks in the schedule from completion of testing to PSR to complete EIDP Can perhaps work the EIDP in parallel with testing to get back some schedule margin if needed
EVM The up-tick in PFP EVM indices show that we are completing instrument fabrication milestones at the planned rate. This has been achieved at the cost of additional manpower resulting in somewhat higher than planned costs in recent months. An updated budget plan is in the works which will show more accurately where we expect to be at completion
Accomplishments Last of the Parts Stress Analyses complete EM progress: All EM testing complete FM SWEA Analyzer delivered from IRAP FM Electronic Progress: 25 PFP flight PWB types fabricated, 7 PWB loaded and in test 19 passed coupon tests (4 failed) 3 failed coupons very recent, all STATIC, built around holidays All remaining bards are being built in parallel by 2 houses 13 PWB being loaded (SWEA/SWIA digital almost done, just waiting on FPGA) MAG MAD & ACHE boards, SWEA IRAP boards in test 2 boards in PWB fabrication (plus the 4 which failed coupons) 1 board still in final layout STATIC ACC/MCP, completed layout review, in final adjustments. All FM parts delivered by GSFC! (some qualification tests remain) FM Mechanical All mechanical parts all out to fab Most parts received and in assembly Operational FSW progress; SEP, SWEA, SWIA, LPW mostly done STATIC starting More in instrument sections…
Ongoing Work Supporting Project planning process Supporting EMC, Payload, SIT working groups Get last FM PWBs out to fab Get FM PWBs loaded Get the last of the board-level thermal analyses complete
PFP RFA Status • Board level thermal analysis supporting the last open SSL CDR RFA has been submitted • Peer review RFA closed (PFDPU Thermal interface) • One more peer review action to go.
Trades, Issues Working on an analysis to decide if the PFDPU mechanical design needs to be augmented to support the PWBs to avoid excessive displacements in vibe Reached agreement on solution (DFB stiffener characteristics) Adds mass to PFDPU to enhance stiffness of chassis. CLOSED PFDPU Thermal conduction to deck Current design does not meet ICD Modifying deck mounting to increase conductivity CLOSED.

MAVEN PFP SWEA Status January 2012 Dave Mitchell, SWEA Lead
SWEA Status – IRAP & SSL • FM analyzer delivered to SSL on Jan. 10! • FM analyzer calibration is complete. • Functional testing with SSL EM electronics was successful. • SSL FM Electronics and Pedestal • SWEA FPGA was reviewed, tested, and flight part is being programmed at JPL expect testing to start week of Jan 16. • SWEA LVPS has been loaded at JPL. • Back at SSL for magnetics loading, test • Pedestal has been fit-checked and is ready for FM electronics
SWEA Issues – IRAP & SSL • SSL manipulator is nearly repaired • Ready to resume investigation of charging anomaly with SSL EM after PSG. • STEREO SWEA was tested in flight no obvious evidence for charging anomaly.
MAVEN PFP SWIA Status January 2012 Jasper Halekas, SWIA Lead
SWIA Progress • Electrical Progress • Most FM PWB fabrication complete • Digital fabricated and passed coupon testing, waiting for FPGA install • Sweep passed coupon ready to load • Preamp in coupon testing • LVPS in fabrication • Anode in re-fabrication (failed coupon testing) • Mechanical Progress • All FM drawings complete and parts in fabrication • More than 70% of parts fabricated and plated • Many remaining parts being plated • Flight Software Progress • Implementation of SWIA onboard processing in progress • Algorithm for moments computation developed • Calibration/Testing Progress • Flight preamp testing in process • First flight board testing starting in the next few weeks
SWIA Issues • Anode board failed coupon testing due to de-lamination • Re-fabrication has begun • Anode board not needed immediately – also very simple, with only passive parts, so very little testing needed until calibration • Slight delay in beginning testing of digital board as a result of minor issues raised at FPGA reviews • Plan to burn SWIA flight FPGA at JPL after quick test of final rev. of EM FPGA (changed staging of DAC control to facilitate quicker HV ramp up, streamlining instrument checkout etc.) • MCP/Preamp board testing plan changed • Now plan to load both halves of the board simultaneously to save time over sending the board out for loading twice • Board CogE’s indicate there is very little risk of preamp damage during MCP supply testing (also, clamp diodes provide protection)

STATIC Open Issues Mechanical procedure development and FM part inspection continuing Calibration vacuum chamber assembly proceeding – problems with manipulators being resolved, ion gun assembly proceeding. FPGA production of data messages P1, P2, P3, P4 and mass histograms need real time verification EM SWP HVPS raw supply needs increased control voltage filtering Test fixtures for delay line part selection being fabricated. Vacuum testing and calibration script writing continuing on EM sensor
MAVEN PFP SEP Status January, 2012 Davin Larson, SEP Lead David Glaser, SEP ME Miles Robinson, SEP EE
Accomplishments, 2012-01-14 DFE Board stuffing done at JPL and returned. Remainder of stuffing starting here. DAP 4 of 6 boards passed coupon tests. 3 Boards going out to JPL for parts loading. Actel version 37 still in testing – decided to ask for version 38 that will remove synchronous outputs. Detectors One set of “flight” detectors delivered – however travelers were not include with them so these will be treated as ETU . Mechanical Painting completed (with exception paddles).
Open issues Paper work is slowing down production
MAVEN PFP DCB, Power Converter & GSE Status January 2012 Dorothy Gordon Timothy Quinn Peter Berg Chris Tiu
DCB Status (1) Data Controller Board DCB ETU #3 has been built and is currently under test DCB Flight Assembly instructions completed Flight coupons passed for two DCBs The two DCB kits have been shipped to JPL for population FPGA Daughter Board Board in-house (received from Valley Syncom) Coupons out for approval Plan to build one test board (using the “dummy” CCGA package and HDLP connectors). Initial process and fit-check prior to installation of AX-FPGA
DCB Status (2) DCB Test/Diagnostics DCB Test Plan is being exercised with ETU#3 Test Plan minor modifications will be incorporated in next revision, used for flight board verification Flight-like PROM installed on ETU#3 Jumper selectable between FSW (boot) and diagnostic section (ROMMON) ROMMON allows for downloading of custom diagnostics DCB FPGA Currently using FLASH FPGA Daughter boards for DCB test Port to AX/RTAX in process for FLIGHT FPGA Daughter board The Coldfire multiply and divide instructions are being exercised/characterized via simulation
GSE Status GSEOS plotting routine enhancements The original Python plotting function, which allowed users to plot housekeeping quantities during a single GSEOS session, updated to allow users to access plot files created during previous GSEOS sessions. First version of a new plotting system completed The new system is GUI driven and uses a database to collect data and make it available for plotting. Users can plot raw or converted housekeeping quantities over the span of data that exists in the database. Labview Interface to GSEOS GSEOS updated to perform telemetry and command control of LabView subsystems drives heaters for thermal vac power/actuator simulator for the High Fidelity Simulator and FSW testing.
Power Converter Status (1) REG The REG EM2 was system tested to demonstrate output voltages, actuator voltages, and deadman timer operation. A small modification was made to the deadman timer (incorporated into the flight/EM3 layout). Bench tests of the EM2 supply were made to verify range of operation and thermal excursions. EM2 was integrated with a DCB to verify the interface, actuator control and housekeeping. The EM3 layout was completed and fabricated boards have been received. Partial population by Digicom (due in on January16th). Coils have been wound and are in test. Remaining parts will be installed on EM3 next week. FM PWB out to fab
Power Converter Status (2) IIB FM board fabrication is complete and coupons have passed. Assembly instructions are in review.
