  9. Occupancy Map TIM Jul07, CERN

  10. Energy Deposition With top layer scintillator coincidence TIM Jul07, CERN

  11. Problems • “noisy channel pair”: jumper cable wire tube end <<>> UFE board crosstalk • “Viking2 on UFE(5+7) “: sporadic pedestal shift on its 32 channels • “1st UDR link WAKE”: pedestal shift in readout -> QM2 S9048 with lower voltage output • “border channel with applied HV”: cable connection induces noise to first/last channel of a module ->1/16 of all channels • “1st UFE channels pedestal shift”: pedestal position dependant on readout frequency (currently under investigation) TIM Jul07, CERN

  12. HV Noise CH1 CH16 UTE Depending on UHVD mounting position HV may also be connected here HV from UHVD Board TIM Jul07, CERN

  13. TRD FM Readout ElectronicsUPD and U-Crate May 07 • Flight Electronics Crates for Readout of complete TRD Subdetector production completed Jun07 • TVT done Jul07 TIM Jul07, CERN

  14. AMS-02 Crates Map TIM Jul07, CERN

  15. CERN Cleanroom 867 FM TRD Readout Electronics Mounted to Jigs 19.Nov U0 / UPD0 U1 / UPD1 Electronics WAKE Jig RAM Jig TIM Jul07, CERN

  16. Electronics Integration Plans • 21.Nov: Mount TRD to USS • 27./28.Nov: Connect DAQ+HV Cables TRD<>U-Crates (Aachen technicians) • 28.Nov: Connection Test (WAKE/RAM) • Connect AMSWire cable to U0/U1 JINF A1 • Connect AMSWire to Aachen DAQ PC EPP-Box (must be nearby) • Power on UPD (by common powersupply? Individual?) • Read out Solid State Fuse Status and TripCounter of FrontEnd Powersupplies (UPSFE-boards) -> check for shorts in powerline • Perform pedestal calibration command on UDR2 boards; Read out calibration results and check for unusual pedestal position and noise values • IF Gas Status Ok: Ramp up High Voltage and check current-protection for shorts; Perform calibration and check for noise peaks (taking advantage of problem) to verify proper connection; ramp down HV • Power off UPD TIM Jul07, CERN

  17. Switch to AMS-system • Script to initialize U-system available on JMDC • HV ramp up script (to be done) • Readout data when trigger is available. Procedure: • Check Gas status (Th.Siedenburg) • Check HV (or ramp up) • Perform DSP pedestal calibration • Start DAQ • (ramp down HV) • Cosmics calibration run • Raw data (maximum data rate?) • Track fit to check for correct cabling • Check for variation in gas gain (MOP analysis) TIM Jul07, CERN
