  3. TRD Octagon Integration (Th.Kirn) 21-APR-2006 I. Özen

  4. TRD Octagon Integration 21-APR-2006

  5. TRD Octagon Integration • All DALLAS temperature sensors tested • All 82 flight frontend boards installed (UFE) • HV ground connections installed • UFE function tests in progress • Gas-tower interconnection tubes installedTower to tower finished next week • Gas-group cosmic tests in preparation • TRD upper plate: Installation of inserts • STA M-Structure machined within specs.Test mounting in preparation • TRD Rosengitter in preparationGastubing / Dallas & UFE cabeling

  6. TRD Longterm Test 2 Years Gastightnessunchanged Gasgainstable J. Hattenbach

  7. Final Report on TRD Front End ElectronicsUFE (Flight Modules)Ch.H. Chung

  8. Production of UFE (FM) Integration + 358VA Chips Tests Select 202 Chips 101Production of 4 Types PCB Series of Space Qualification Tests Functional Tests TVT  3D Vibration  Coating  TVT

  9. Space Qualification Tests Random Vibration X,Y and Z-Direction aRMS = 6.8g, 20-2000 Hz for 120 sec Functional test without failure 1st TVT Temperature : -40oC … +80oC Pressure : 110-5 mbar Functional test without failure 2nd TVT Same as 1st TVT condition Conformal Coating

  10. Thermal Profile in TVT Operating Temperature (-20 ~ +50 oC) : Gain Calibration Points

  11. Noise after SQT Noise = 1.5 ADC == ENC = 4000 e- Common mode noise corrected Pedestal RMS

  12. Gain Calibration +50 oC -20 oC

  13. Gain vs. Temperature All 6464 channels are calibrated over full Temperature range

  14. Flight UFE Selection ALL 101 produced UFEs within specificationsSelect “better“ UFEs as flight modules

  15. TRD-UFE (FM) Pedestal Distribution : ~ 10% of full range

  16. TRD-UFE (FM) Noise RMS Spread : ~ 4%

  17. TRD-UFE (FM) Gain RMS Spread : ~ 3% 25oC

  18. TRD UFE Summary UFE(FM) Production : Finished (Jul. 2005) Total = 101 UFEs (FM = 82, FS = 19) Functional Tests : Finished (20.07.05) UFE Space Qualification Tests (Mar.05 ~ Mar. 06) 1st Thermal Vacuum Test = 101 (Done w/o failure) Random Vibration Test = 101 (Done w/o failure) Conformal Coating = 101 (Done w/o failure) 2nd Thermal Vacuum Test = 101 (Done w/o failure)  Best 82 FMselected (Mar. 2006) UFE Integration : Finished (Apr. 2006)

  19. TRD Gas Manifolds • Distribute TRD gasflow into 41 segments • Measure gastightness of individual segments • Allow isolation of a segment when leaky • Introduce no additional risk of gas leakage

  20. Manifolds mounted on Octagon

  21. OctagonTemperature Swing +30 R,P,Y hottest OHB TRD Thermal Report 240 days (4 b periods) eMLI = 0.03 Average TRD Temperaturebetween +35oC and -20oC Depending on ISS R, P, Y 0 R,P,Y coldest -20
