Crate 5 --> TOWER FEE and Database Mapping Tests


  • Tower crate 5 covers 10 subsectors 7D - 9C
  • Procedure:
    - set HV only for eta bin 1 in all 10 subsectors
    - pulse LED with masks x02,x04,x08,x10, and x20 injecting light to subsectors A,B,C,D,and E, respectively. For each mask take separate run.
  • Expected display patterns:

  • Results

    Probably due to the cross crate timing issues no LED peaks in 7D & E are visible (?need to check with WJ).

    A separate plot for every eta bin is made, following the pattern of the above tables. X-axis range 0-4095. Although pedestals were subtracted, but the ped values were about week old, so 1-2 channel difference is often visible.

    Log-log scale is used so plots look funny. Two hints:
    LED signal is a narrow peak in the middle of the plot. 'Empty' spectrum has nonzero values in the ADC=0 bin.
