GLAST LAT ProjectMonthly Review, Aug-1, DAQ & FSWV1 1 GLAST Large Area Telescope: Electronics, Data Acquisition & Flight Software W.B.S Aug-1 Monthly Review Gunther Haller (650) Gamma-ray Large Area Space Telescope

GLAST LAT ProjectMonthly Review, Aug-1, DAQ & FSWV1 2 TEM/TPS Status Status –All units delivered by assembly vendor. Contract being closed. –Qual unit review still to occur –14 flight units delivered to I&T A & B & 12 more units –6 units ready to be reviewed (i.e. finished/passed all testing) 2 of those units were demated and will be used to replace TwrA and TwrB TPS’s –Last unit in TV until next Sunday To do –Review of end data packages for 4 units above –Review of last unit presently in TV –Modification of 2 TPS’s taken off TwrA and B Mating with TEM’s Vibration End data package review

GLAST LAT ProjectMonthly Review, Aug-1, DAQ & FSWV1 3 PDU Status and Schedule 1st unit (flight) –All testing complete –To do: Closing of NCR’s Collecting/posting data Review 2 nd unit (spare) –Pre-coat stage box just received at SLAC –Testing (safe-to-mate & performance) to start next week –Followed by Return to vendor for conformal coating Environmental testing –Schedule depends on setting priorities compared to other modules (e.g. SIU). Assume low priority compared to all others for now.

GLAST LAT ProjectMonthly Review, Aug-1, DAQ & FSWV1 4 GASU Status and Schedule First Unit –In conformal coating at vendor, followed by integration with flight harness –From last months review: Estimated Delivery of final box at SLAC: Sept 15 –Best estimate is now Sept 21 due to parallel work on SIB, etc Followed by test/mass/TC/test/vib/test/TV: 23 days Followed by EMI (10 days) Estimated delivery to I&T: first week of November Schedule for 2nd unit –Estimated delivery to I&T: 6 weeks after delivery of first unit

GLAST LAT ProjectMonthly Review, Aug-1, DAQ & FSWV1 5 SIU/EPU (1) SLAC Qual testing of boards assembled at Aeroflex –Testing was all completed without failures –To do: correlate pins tested to results of X-rays from GSFC, await file from GSFC Backplanes –Assembled cCPI connectors on flight backplanes at SAI SAI assembled 7 backplanes (3 to follow) I had short, neither SLAC nor SAI could repair. However pins are not used so NCR with “use-as-is” 7 boards were xrayed, some pins were touched-up, re-xrayed –3 board were mailed to Aeroflex for remaining assembly –Are in conformal coating followed by harness assembly –Additional ones will be mailed to Aeroflex after balance of 3 backplanes from SAI are received and evaluated and compared to other 4 backplanes. –Hope to receive at least 1 fully assembled backplane end of next week (for proto-flight testing of SIU)

GLAST LAT ProjectMonthly Review, Aug-1, DAQ & FSWV1 6 SIU/EPU (2) 1 st SIB, LCB, CPS (for proto-flight testing of SIU) –One each was tested, pre-conformal stage –(also xray’s were taken and some pins were touched up, the connectors had been assembled at AF before SAI experiments started) –Integrated in SIU crate with RAD750 processor Short performance tests at –40C and 55C passed –Boards were sent back to Aeroflex for conformal coating –Final SIB and LCB assemblies were received at SLAC yesterday –CPS expected beginning of next week –Note that this SIB contains chlorine-contaminated EEPROM, other modules could be flight 2 nd and 3 rd SIB/LCB/CPS (for 1 st and 2 nd flight SIU/EPU) –cCPI connectors were assembled at SAI –Xrayed and touched-up at SLAC –Sent to AF for further assembly –Pre-conformal coat boards expected next week for testing at SLAC –Followed by conformal coating –Integration in 1 st and 2 nd SIU (or EPU) –Environmental testing –Expected delivery to I&T 11/30 –12/5 Remainder of crates follow in 5-day increments (mainly TV) –cCPI connectors were just assembled by AF on boards –Manual assembly will follow EEPROM for SIB: –Passed CSI at Austin Semi –Delivery to SLAC is Sept 15

GLAST LAT ProjectMonthly Review, Aug-1, DAQ & FSWV1 7 Harness & Heater Control Box & Interconnect Box Harness in assembly, almost complete (some spare cables in rework) HCB –Boards assembled –Await harnesses and enclosures –Assembly lower priority compared to GASU/SIU HIB (Interconnect box) –Parts kitted at SLAC –To be assembled at SLAC

GLAST LAT ProjectMonthly Review, Aug-1, DAQ & FSWV1 8 Thermo-testing support/ VSC EGSE for thermal-test shipped to Lockheed TV Testing to be completed end of this week VSC’s available for FSW/I&T –Remaining features of VSC being implemented
