1 PFP MSR, 2/14/2011 Particles and Fields Package Monthly Status Review (MSR) February 14, 2011 Dave Curtis, PFP PM 2 PFP MSR, 2/14/2011 SSL Contracting Status Phase B/C/D Contract in place. A budget breakdown by PFP schedule milestone has been submitted to support EVM at GSFC A funded schedule margin budget has been provided to support EVM at GSFC 3 PFP MSR, 2/14/2011 Schedule Status EMs have made a lot of progress this month All layouts complete, most boards are in test SWIA/STATIC mechanical making progress, but continues to lag EM Package I&T starts in March with LPW But does not complete till after instrument CDR (end of May) SWIA, STATIC calibrations dont complete till after Package I&T Working around manpower shortages caused by continuing work on other projects (such as RBSP) Some slippage in post-CDR schedule margin, mostly off the critical path. Due to late EM I&T Still have 15 weeks of margin to delivery on critical path (Flight Software) Working on ways to improve margin 4 PFP MSR, 2/14/2011 Manpower RBSP-EFW instrument still not delivered this month? Most of the people we need have transitioned 100% a few still completing other tasks, notably key technicians, QA, power converter test engineer, thermal engineer An issue with RBSP flight hardware lost us a tech and test engineer who looked like they were transferred to MAVEN last month Worked out a scheme to use campus technician pool Not NASA certified, but can help with EM and GSE Solar Probe Plus is starting to impact a few team members Looking at ways to share and augment team as needed We are well under planned FTE rate Mostly due to people splitting time between projects Plan was based on conservative assumptions about covering people 5 PFP MSR, 2/14/2011 Accomplishments ALL PWBs layed out, many loaded and in test see below DCB has started test with Boot software Key element for EM I&T with LM in April Most EM Mechanical parts are in fab Some part-level design work still in progress on SWIA/STATIC Hope to have most parts out for fab by the end of the month STATIC EM TOF Acoustics Test this month STATIC, SWIA grass-roots mass update complete (mass is up) SEP EM attenuator mechanism in test All required EM EEE parts at SSL All flight Active parts are on order Passive parts list being updated, ordering in progress Radiation tests are proceeding well, no show stoppers so far More in instrument sections 6 PFP MSR, 2/14/2011 Ongoing Work Supporting Project planning process Supporting EMC, Payload, SDT working groups Completing EM board loading Continue EM board testing Completing EM mechanical part drawings, getting parts fabricated Preparing for the start of PF Package EM I&T, LM EM I&T 7 PFP MSR, 2/14/2011 EM Status Summary PFP EM & GSE Layouts 31 total, including GSFC/MAG, LASP/LPW, CESR/SWEA ALL 31 layouts complete (29 boards fabricated, 22 boards loaded, 8 completed test) PFDPU to Instrument Integration starts soon LPW delivers first ~3/15, continues through May LM Interface Test preparations (4/5/2011): DCB board loaded, in software test Current schedule shows ready by 3/10/2011 for the LM test EM Mechanical parts: STATIC EM TOF, SWIA Anode/MCP complete, in test Remaining SWIA, STATIC parts into fab soon SEP, LPW EM in mechanical in assembly SWEA EM analyzer, housing ready for electronics integration 8 PFP MSR, 2/14/2011 EM Status 9 PFP MSR, 2/14/2011 PFP RFA Status 10 PFP MSR, 2/14/2011 Trades, Issues HV801 issue still open Two options: Amptek HV801, Micropac Amptek delivered some EM HV801s Have parts for EM Current plan is to buy HV801s from LADEE NMS, who has parts on order they no longer need Also have an offer of some extra parts from LASP 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 MAG EM PWB has option for a center support, others do not Looks like we can probably eliminate center support, analysis about ready for review We recently vibrated the EM DCB (low level sine sweep) to verify resonant frequency and Q: Q higher than expected. Working this into the analysis. 11 PFP MSR, 2/14/2011 Thermal Status Updated Thermal Model delivered We found a discrepancy between this new model and the previous one Due to use on Black Nickel in SWEA, SWIA, STATIC apertures; lower emissivity that previously modeled Had to adjust model to maintain temperatures add a radiator area where design was previously blanketed while trying not to impact operational heater requirements This delayed delivery of the models to LM LM wants us to reduce the number of nodes in our model. They accepted full models for the PDR delivery Reducing the number of nodes reduces fidelity Reducing the number of nodes will take ~2 weeks. 12 PFP MSR, 2/14/2011 Top Risks P-18, 19, 20 new 13 PFP MSR, 2/14/2011 Risks List 14 PFP MSR, 2/14/2011 PFP Mass Grass-roots mass estimate (including as weighed EM electronics) made for SWEA, SWIA, STATIC SWIA and STATIC mass up Electronics box walls increased to 100mils for radiation shielding Enhanced fidelity in analyzer Changes strategy for mass reallocation 15 PFP MSR, 2/14/2011 Mass Tracking Chart 16 PFP MSR, 2/14/2011 PFP Power No significant change to CBE 17 PFP MSR, 2/14/2011 PFP Power Trend 18 PFP MSR, 2/14/2011 PFP Data Rate Per allocations from Bruce 19 PFP MSR, 2/14/2011 Requirements Verification Status Reviewing PFP Functional Requirements (Level 3) some old requirements need updating Once updated, will start mapping into Verification matrix Need DOORS verification output for ICD and ERD to include in the matrix ERD and ICD still evolving When do we snapshot these? Boot software verification has started against software level 5 requirements, which link back to FRD and ICD. 20 PFP MSR, 2/14/2011 Drawing Status 73% of 647 EM drawings released SWIA and STATIC mechanical lagging Released EM drawings are draft FM drawings Typically will not be released for FM fabrication until completion of EM testing Some are released earlier where risk is low 21 PFP MSR, 2/14/2011 MAVEN Magnetometer Status February 2011 Connerney, Sheppard, Schnurr, Oliversen, Espley, etc. 22 PFP MSR, 2/14/2011 GSFC/MAG - Accomplishments Last Month(s) EM sensor completed & awaiting pigtail installation (cable due/LM).

SWEA Pedestal SWEA Digital purge port bracket 32 PFP MSR, 2/14/2011 MAVEN PFP STATIC Status February 2011 Jim McFadden, STATIC Lead 33 PFP MSR, 2/14/2011 STATIC Accomplishments Carbon foil floating automated Carbon foil scanner shown capable of determining foil thickness, identifying foil tears, and contamination from bits of foil (see photo) Procedure established for carbon foil frame cleaning to remove carbon foils that do not pass inspection allowing re-use of frames Carbon foil documentation procedures established EM Anode and Preamp board in test EM Digital board and daughter board loaded (see photo) and in test EM TDC board fabricated (see photo) EM HV Sweep PCB fabricated (see photo) EM LVPS loaded except magnetics. All mechanical parts for acoustic test are fabricated except MCP clamping springs TOF subassembly parts cleaned and assembled for acoustic test Clean-room (320) functional - ready for use during analyzer assembly Old vacuum calibration chamber readied for EM vacuum testing 34 PFP MSR, 2/14/2011 Carbon Foil Inspections Tears in foil are easily identified Contamination from bits of carbon foil floating under the grid frame and attaching to the bottom creating a double foil. New frame mounting holders under development should eliminate problem. Foil coverage and inspection can be automated with scanner tools. 1 cm 35 PFP MSR, 2/14/2011 STATIC EM Digital Board and Daughter 36 PFP MSR, 2/14/2011 STATIC EM TDC (left) and Sweep HV 37 PFP MSR, 2/14/2011 STATIC Open Issues Carbon foil frames need to be placed in TOF units for acoustic test. Mounting fixtures for handling flight carbon foil frames need to be fabricated to prevent small bits of carbon foil from attaching to the bottom of frame Low yield problems with floating 0.5 ug/cm 2 carbon foils (bad foil batches) we ordered higher cost foils deposited on mica, rather than glass slides, to test for quality differences Additional equipment for clean-room 320 needed (cabinets, tables, etc) EM HV Sweep board being kitted, shield wall design in process EM TDC board being kitted 15kV-MCP board needs to be kitted - waiting on HV connectors, mechanical parts. STATIC FPGA still in development (EM version ready for test) LVPS needs magnetics (transformers) loaded and tested (Berg). Analyzer and mechanical attenuator still in development Some test harnesses and test cables need to be fabricated 38 PFP MSR, 2/14/2011 MAVEN PFP SEP Status February, 2011 Davin Larson, SEP Lead 39 PFP MSR, 2/14/2011 SEP Accomplishments Mechanical attenuator tests started. First testing using GSE (MISG) GSE working properly. Initial assembly had micro-switch mis-aligned which resulted in failure on first overnight test because attenuator got caught in a position with both switches open. Micro-switches re-aligned, ready for retest but not yet retested. Resolved questions about plunger force. Silicon detectors are diced and tested. To be delivered in mounting stack by Craig Tindall next week. DAP board stuffed with parts (2 channels only) Some parts (OP462) were not stuffed by digi-com but were inserted at SSL. FPGA design in delivery. Expect visit from Jianxen Chen on 02/18. Mechanical parts have arrived.
