LiI measurement campaign

First campaign - no amplifier

Summary of the runs

  • From LiI_SelfTrigger_HV_750V_UG_Thermal_20240530_205303.root to LiI_SelfTrigger_HV_750V_UG_Thermal_20240627_112642.root
    Partly good, 30 min, DAQ crashing randomly because we used the wrong USB port on the DAQ laptop. Only files with an actual 30 min duration are usable.
  • From LiI_SelfTrigger_HV_750V_UG_Am_20240703_180931.root to LiI_SelfTrigger_HV_750V_UG_Am_20240709_150126.root
    Partly good, 30 min, Am source placed in front of the crystal, DAQ crashing randomly because we used the wrong USB port on the DAQ laptop. Only files with an actual 30 min duration are usable.

Second campaign - with amplifier

The signal is amplified by a factor x10, and with a low-pass filter (the bandwidth should be 100 Mhz).

Summary of the runs

  • Gamma calibration
