SSL Contracting Status

• Funded through the end of April• More info in the Business Splinter presentation

3PFP QSR, 4/19/2011

Schedule Status

• EMs have made a lot of progress this month– All EM PWBs in test but ~2 (HVPS boards, in fab)– SEP, LPW, SWEA, MAG EM mechanical assembly complete– STATIC EM TDC complete random vibe– SWIA/STATIC analyzers parts out to fab

• EM Package I&T in progress– LPW, SEP, SWEA test with PFDPU complete– EM ‘Early Payload Test’ with LM complete– MAG next week– Pushing to complete before CDR– EM Instrument calibrations don’t complete till after Package I&T

• STATIC is on critical path– 13.6 weeks margin to delivery– Driven be delays in EM I&T

• Status at instrument CDR – SWIA, STATIC EM will not be complete– SWIA, STATIC attenuator life test not done– SWIA, STATIC power converters may still be in test– Rest of instrument EM will be complete, with perhaps some system

level test still in progress

4PFP QSR, 4/19/2011

Manpower

• RBSP-EFW instrument still not delivered – this month?– A number of problems encountered in thermal vacuum– Resolving those problems have impacted MAVEN power

converter team, delayed STATIC & SWIA

• We are still under planned FTE rate– but climbing a bit– Mostly due to people splitting time between projects

• Note that 100% activity is often more than 40 hours/week in these cases

– Plan was based on conservative assumptions about covering people

5PFP QSR, 4/19/2011

Accomplishments

• LPW, SEP, SWEA EM integrated with PFDPU EM• PFDPU EM Early Payload test with Spacecraft EM• SWEA Peer Review Completed• STATIC Random Vibration Completed• SEP Attenuator Life Test Completed

• More in instrument sections…

6PFP QSR, 4/19/2011

Ongoing Work

• Supporting Project planning process• Supporting EMC, Payload, SDT working groups

Trades, Issues

• HV801 issue still open– Current plan is to buy HV801s from LADEE NMS, who has parts

on order they no longer need.– We still don’t have the parts in hand

• 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– Analysis complete, passed on to GSFC expert for review.

• LPW Stacer Plating issue (NEW)– After plating stacer with black Nickel it no longer stows properly– Need plating for thermal reasons (aeroheating, thruster heating)– Historically we have used a paint (DAG213), but that will not

survive atomic oxygen at Mars– Working with GSFC Materials on possible solutions

10PFP QSR, 4/19/2011

Thermal Status

• Received ‘Thermal Memos’ as well as spacecraft thermal model

• Some of the instruments are in trouble according to the thermal memo– For example, STATIC goes to -100C

• We are working on identifying if the issue is the model or the design– Our preliminary results are more benign

Boom Deployment

Mission Performance

1 3 L

Waiting till after MOI to deploy LPW booms results in them sitting undeployed for over a year, increasing the risk of deployment failure

Potential severe degradation of LPW measurement

Far Term

Investigate if LPW booms can be deployed early

Research Early deployment of LPW booms reduces this risk. Actual risk of failure is very low. Risk that we may be asked to do an expensive verification is moderate

P-14 HV801 ProblemProject

Execution1 3 L

If HV801 not available a redesign would be required to use alternate (larger) parts

Schedule, Mass Near Term

Watch what programs ahead of MAVEN do; look into alternate parts

Mitigate Micropak alternate part in test. EM parts found, FM parts identified

P-17Parts

33PFP QSR, 4/19/2011

STATIC Accomplishments

• Carbon foils mounted in TOF units survive vibration test – automated software used to evaluate foil breakage

• Ordered carbon foils on mica slides to improve mounting yield • The design of START foil grid-frames was modified to compensate for

poor clamping due to fabrication tolerances - new grid-frames ordered. • Design of attenuator motor completed, drawings for ETU in process• Energy analyzer/deflector parts drafted and ordered • EM TDC board bench testing complete, part modifications made• EM preamp 1 modified and working adequately for integration w/ TDC

board – will be used while optimized preamp board is developed • EM Anode, Preamp and TDC boards integrated – working• EM Digital board passed power and PFDPU simulator interface testing,

ready for interface test with TDC• EM Sweep HV board partly loaded and in test (see pictures)• Clean room equipment installed – racks, SS table, GN2 purge, etc.• Helmholtz coil template fabricated, waiting on welding before assembly

34PFP QSR, 4/19/2011

STATIC EM Sweep HV Board

35PFP QSR, 4/19/2011

STATIC Open Issues

• One of two TOF electrical connections broke in 1 of the 3 units during vibration test (see pics) – connection redesigned for stress relief

• Mounting fixtures for handling flight carbon foil frames need to be fabricated before additional EM carbon foils are loaded

• New START foil grid-frames will require inspections after fabrication• Preamp design changes nearly complete for optimal dynamic range –

may require new layout• EM 15kV-MCP board changed, MCP “stack stick” multiplier abandoned

in favor of a pair of VMI multipliers and a tapped transformer – EM waiting on part placement changes (Berg).

• Digital board FPGA still in development• EM LVPS loaded – waiting to be tested• Manipulator fixtures for calibration chamber testing in development• Some test harnesses and test cables still on order• New calibration chamber ordered – delivery late May• SS sink for clean room assembled – waiting for drain assembly

SEP Accomplishments2011-04-12

• Mechanical attenuator tests completed – ~4500 cycles completed (all but ~1000 in vacuum)

• Integration of DAP board (& ½ sensor sans detectors) with PFDPU begun on 2011-04-11

– Safe to mate –ok– Initial power on - ok

• but receiving +6V and -6.3 volts instead of nominal +/- 5V– Command test – ok

• Successfully turned on test pulser• Bias voltage setting not working (not yet functional on DAP?

– Telemetry tests – ok• Successful run of ‘SEP_DAPINIT’• Unbalanced analog voltages result in offset from baseline• Successful run of “SEP_THRESH_SWEEP”• Successful run of “SEP_TPSWEEP”

– Some cross talk visable that was not seen with MISG– Noise level is substantially larger and assymetric

– Timing Tests – skipped – SEP Aperture tests – ok– SEP auto aperture closure – problem on REG– SEP power inrush current test - OK

• ETU Silicon detectors (1 stack) delivered on 2011-04-12.• DAP board

– 3 channels loaded on DAP #1– 12 channels loaded on DAP #2– Actel programming: Using FPGA version 0x32

42PFP QSR, 4/19/2011

Attenuator life test

• Life tests were done on 3 separate days.

• TCP/IP connection from computer to MISG was unreliable.

• Difference in actuation time is probably temperature related.

43PFP QSR, 4/19/2011

Attenuator Stroke vs. bus voltage

• Tested the range of bus voltages that would cause actuation.• Below 22 V (2.08 V across nanomuscle), actuation failed in air.

44PFP QSR, 4/19/2011

SEP Open issues

• What voltage to use for +/- 5VA supply.– Analog supply NOT currently regulated– Need secondary regulation for A250?– Eliminate requirement of 5V Digital altogether

• Mods needed for flight DAP board:– Use faster transisters on pulse generator (fixes 3.3 volt logic problem)– Use 2.5V reference instead of 5VA for baseline trim– Use Valid signal for hysteresis on peak detect– Gain change on peak detect circuit (perhaps not needed now)– Switch from 10 MΩ to 1MΩ resister on bias voltage control– 5 MΩ resistor to -5VA (-2.5R?) to correct for OpAmp input current (this mod is questionable if BLRena mode

is working properly)• Sensor

– Add detectors!!!!– Insert caps on attenuator lines to clean up some noise

• FPGA Mods from version 0x32– Eliminate secondary pulse by applying BLRena for 6 μsec on test pulse return– Extend test pulse duration from 10 μsec to 20 μsec – 16 bit counters on no peak counters– Ability to turn off housekeeping measurement– Event mode resolution

• Testing:– Purchase new nimbin and test pulser to replace AWOL test pulser– Test for correct coincidence determination with FPGA– New radiation source

• PFDPU testing– Cross talk observed in PFDPU but not MISG?– Increased Noise observed in PFDPU (probably resolved with shield boards)– Telemetry dropouts from PFDPU science packets– Possible change in opto coupler wiring of actuator control on DCB to eliminate any possibility of noise

• Baseline shift at high count rates – (probably not an issue)• 1 mv shift in baseline shortly after the 1 pps signal• More to come

• GSEOS– Python modules added to perform checksum processing and

verification on PFDPU telemetry – Python module added to support PFDPU Memory Loads – Delivered first rev of STATIC configuration – Created Python module for playing back raw data over TCP

link with GSEOS – Supported LPW EM integration testing

52PFP QSR, 4/19/2011

Power Converter Status (1)

• REG Board • We are working on a second PCB layout for the REG board

ETU#2 due to a connector mis-wiring issue on the first layout. This re-layout process has begun.

• The REG board tester was built and is now in operation• All REG based switchable services have been tested• Still pending: adjustment/tuning of the current monitoring

subsystem; complete verification of the digital portion of the circuit

• REG Board system checkout via PFDPU I/F Tests• DCB Interface/Housekeeping addressing• Instrument Power Switches

53PFP QSR, 4/19/2011

Power Converter Status (2)

• IIB board• All power converter sections of the EM board have been tested with only

the magnetics of MAG2 and off board connectors for STATIC, SWIA, and MAG left to be populated.  (This excludes the MAG HEATER daughter boards from Goddard that are to be mounted on the IIB at a later date.)

• The ±90V outputs on the LPW section sat at 114V when integrated with the system.  This would indicate an unloaded state as the voltage would normally drop closer to ±90V when loaded (10mA peak).

• The 5VD regulator on the SEP section will be changed to an LDO as the actual load is much lower with the system.  The LTC1877 may have stability issues with such a low load.

• ACTEL turn-off delay circuit for the LPW section will be added and tested on the EM board.

• Optimization for noise, efficiency, and voltage levels will also be done after and in between integration.

54PFP QSR, 4/19/2011

Concerns/Issues

• PC104 Connectors– One of the Hypertronics PC104 connectors delivered to us appear

to have been assembled incorrectly– Connectors are very fragile, pins have bent and even broken during

our ETU testing• We have implemented a mating procedure to mitigate this issue

– We still need to verify the connection insertion is met with the boards installed in their frames

• Schedule– Schedule for testing is tight– As the integration progresses, we are finding issues that require

resolution (e.g. power supply regulation, clock distribution). We need time to sort through all the open-items (hopefully prior to CDR) yet the individual subsystem testing/tuning is still ongoing.
