  1. AMS Software Review ACCDAQ Monitoring Ch Chung, A. Goerres, Th. KirnI. Phys. Institute B,KSC, 31st January 2011

  2. ACC DAQ Monitoring ACC Electronic Scheme:

  3. ACC DAQ Monitoring • History: • Starting time: Cosmic Data Taking Period at CERN after • AMS-02 Pre-Integration May 200 by • Ph. v. Doetinchem, continued by A. Goerres • to be continued by Ch. Chung + Th. Kirn

  4. ACC DAQ Monitoring Block-Files Mean ADC values for each of the 4 PMTs of S0, S1, S2 and S3 crate Median ADC values for each of the 4 PMTs of S0, S1, S2 and S3 crate Number of TDC Hits for each of the 4 PMTs of S0, S1, S2 and S3 crate mean JLV1 trigger pattern for each AND/OR of PMTs corresponding to one set; SFEA board temperature sensors, Global DALLAS sensors on each PMT box

  5. ACC DAQ Monitoring S0 WAKE +Z S1 RAM +Z S2 WAKE -Z S3 RAM -Z Black (SFEA2 input channel 0) Red (SFEA2 input channel 1) Green (SFEA2 input channel 2) Blue (SFEA2 input channel 3)

  6. ACC DAQ Monitoring S2 WAKE -Z Black (SFEA2 input channel 0) Red (SFEA2 input channel 1) Green (SFEA2 input channel 2) Blue (SFEA2 input channel 3)

  7. ACC DAQ Monitoring Mean ADC values for each of the 4 PMTs of S0, S1, S2 and S3 crate Calculated out of 500 ADC values, not pedestal corrected S0 WAKE +Z S2 WAKE -Z S3 RAM -Z S1 RAM +Z Black (SFEA2 input channel 0) Red (SFEA2 input channel 1) Green (SFEA2 input channel 2) Blue (SFEA2 input channel 3)

  8. ACC DAQ Monitoring Median ADC values for each of the 4 PMTs of S0, S1, S2 and S3 crate Median value range 700 – 1000, ADC value range 300 – 2000, Running value: ADC value above median → median increase by 0.5 ADC value below median → median decrease by 0.3 S0 WAKE +Z S1 RAM +Z S2 WAKE -Z S3 RAM -Z Black (SFEA2 input channel 0) Red (SFEA2 input channel 1) Green (SFEA2 input channel 2) Blue (SFEA2 input channel 3)

  9. ACC DAQ Monitoring Raw Data: Stored time marks of discriminator transactions in TDC

  10. ACC DAQ Monitoring TDC: Discriminator threshold for all channels set to 200

  11. ACC DAQ Monitoring Mean number of TDC Hits, averaged over 1500 entries S0 WAKE +Z S1 RAM +Z S2 WAKE -Z S3 RAM -Z Black (SFEA2 input channel 0) Red (SFEA2 input channel 1) Green (SFEA2 input channel 2) Blue (SFEA2 input channel 3)

  12. ACC DAQ Monitoring • JLV1-trigger: Percentage of events which get a veto-flag • ADC values as a function of the corresponding JLV1 pattern • events with JLV1 off pattern for certain PMT contribute ~10% at 500 ADC counts and ~0.1% at 1000 ADC counts at threshold 200

  13. ACC DAQ Monitoring Temperature Sensors S-crates, Temperature Sensors on PMT-boxes Operational: -30°C … +45°C Non-Operational: -35°C … +50°C

  14. 2010 KSC Cosmic Data Period → ACC Stability

  15. 2010 KSC Cosmic Data Period - TRD-track for prediction of ACC-hit - only the center of panel is taken into account Ram Wake

  16. 2010 KSC Cosmic Data Period ACC Signal MOP / 1000 events 2010.09.01 – 2011.01.21 Zoom .. Change of Trigger Conditions: “1 out of 4”

  17. During ISS end to end test period all 16 PMTs are stable less than 2% level

  18. 2010 KSC Cosmic Data Period ACC Stability Wake +Z RAM +Z Wake -Z RAM -Z
