Agenda/Notes:

  • Any testing or data analysis update
    • ePix100 Gain calibration (finished data collection 2 out of 7)
      • Philip has made the Sbatch script working, so we can assign the data analysis to  compute nodes.
      • Data collection (7 epix100 units done) , etch 30 unit may need redo.
  •  
    • ePixM units status–Xavier
      • In total: 8 new ePixM units with 4 ASICs, 3 old detectors (1 out of 3 died during the beamtime), so 2 old working units now.
      • 8 New units with 4 ASICs: 
        • RX003_4ASICs: 3 ASICs work
        • RX004_4ASICs: 4 ASICs work but quite a few lanes don't work on one ASIC (best detector so far)

        • RX006_4ASICs: 3 ASICs work, one ASIC gives strange pictures with the laser  

        • RX008_4ASICs: 3 ASICs work, one doesn't

        • RX009_4ASICs → problem when powering the board! Cannot test it. 


        →I still need to test the 3 remaining ones. 
      • HV biasing Voltage determination (Presentation)
        • Recommended voltage ~-80V.  (-60-70 should also be fine).  
        • Burn test over the weekend at -85V.  Check to see that current draw is stable.  


    • ASC setup development – Zongde
  • No labels
