Thursday November 25

  1. Last 24h:
    • Solenoid ramped down, cryotarget removed and replaced with the carbon foils (work finished ~12:00)
    • Beni started to ramp up the solenoid. ~19:00 tune beam was delivered into the hall. After harp scans and finishing with the solenoid ramp up, DAQ was prepared for production.
    • First Carbon run at 150nA started ~11:30
  1. Issues:
    • DAQ computer was frozen during the afternoon, so a hot reboot was necessary. That could cause some communications issues with some racks, especially with the Pair Spectrometer.
    • Besides that issue, I suggest limiting the DAQ computer just for CODA. I had the experience that the computer gets freeze or lose the GUI when is used with other apps.
  1. Plan:
    • run on carbon at 150nA´
    • Rotate the radiators and use both configurations
      • It was suggested to stop the beam ALWAYS before changing the radiator configuration (even with the same radiator)
    • Take at least two amorphous runs
  1. Analysis update
