1. SPP/FIELDS Quarterly UMN 27 September 2016
Keith Goetz

2. UMN Activity
UMN contract with SwRI is producing good results - at a price
Nearly complete
Flight hardware assembly is well along
All UMN flight hardware is complete and delivered to UCB
LNPS1 delivered to I&T at UCB
LNPS2 delivered to I&T at UCB
TDS delivered to I&T at UCB
Integration was successful
Final end-to-end calibrations were recently completed with flight preamplifiers
Final conformal and such remain

3. UMN Activity
FIELDS slices at UCB (July)

4. FIELDS2 Activity On-going development of FPGA/VHDL firmware
A second flight-like proto-RTAX was burned and tested
Corrected serious timing problems in earlier VHDL design
EM testing shows the problems was corrected
Proto-RTAX was installed in FM and is full functional
On-going development of flight software
On-going development of ground software

5. TDS Activity TDS FM is now fully assembled and tested Issues Resolved
Screened ADCs were delivered and installed
At risk – lot jeopardy – as qualification continues to mid-November
Instrument calibration is now complete
Stability will be revisited throughout I&T
Issues Resolved
Circuit Breaker design error (typo) – introduced in FM
Corrected, implemented and tested
Circuit Breaker mixed voltage – introduced in STEREO
V5 Gain error – overlooked in EM testing
Non-flight (no PIND testing) AD829 op-amps installed by accident
Corrected (replaced) and tested

6. TDS Status TDS FM is assembled and in I&T at UCB
Proto-RTAX has been installed
Corrected AEB clock problem revealed in I&T
Full end-to-end phase and gain calibrations have been done
TDS EM1 used at UCB with SWEAP FM to verify wave particle correlation (WPC) with real particles!
TDS EM1 is in normal use in EM stack at UCB
Timing compatibility with DFB and MAG instruments demonstrated
TDS EM2 is constant use at UMN
Continuing development of flight firmware, software and ground software
FPGA/VHDL has seen continuous development
Working data down-sampling

7. TDS WPC

8. LNPS Activity LNPS1/2 FMs are complete and ready for final assembly
Instrumented TV conducted on both FM units
Verified heat rejection and hot spots
Delivered to UCB I&T
LNPS1/2 FMs have a tin-whisker issue
Magnetic parts have been built with tin-plated cans
Mitigations are understood
Large scale size
Tag plate pins fully solder coated
Conformal will be applied effectively to can interiors, exteriors and boards
No bare metal - Impedes growth and penetration
Voltages/currents will burn whiskers away
PMPCB approved – with waiver
LNPS1/2 EMs are complete
Functional at UMN (1) and UCB (2)

9. Parts Activity Parts and materials lists are complete
As-built parts lists complete
De-ratings have been revisited
AD7621 ADC is not yet fully approved
AD7621 ADC beam testing accomplished at Texas A&M
Test write-up complete
Commercial PEM qualification is on-going – to mid-November
Vendor has not inspired confidence
PMPCB suggested long (7d) duration hot test is running at ambient
Scope captures of circuit-breaker action will be captured on FM at UMN
Waiver for not beam testing implemented circuit breaker is in the works
Magnetics tin-whisker issue is resolved
PMPCB has approved
Mitigations in place
Waiver is in the works

10. Coming Up Flight hardware will return to UMN
Final soldering touch-up
Final cleaning (ROSE)
MIP
Staking and conformal
Final assembly
Flight hardware will be re-tested at UMN
Flight RTAX to be burned, assembled, tested and installed in FM TDS
Flight PROM to be burned, tested and installed in FM TDS
Flight hardware will be re-delivered to UCB – November
FIELDS1 and FIELD2 re-I&T at UCB
PER
FIELDS environmental test program
PSR

11. Financial Activity
UMN spending continues within contract plans (thru August)
Target CV is $6.7M
Spending continues somewhat
behind the proposed
