This experimental setup does not contain BorAl

General run plan

  • Run source in and source out in experimental setup and background subtract with NaI
  • Move the source to different locations along the source tunnel and plot the different distances and count rates
  • Run source in and source out in experimental setup and background subtract with He3
  • Move the source to different locations along the source tunnel and plot the different distances and count rates

I will upload some models of the setup when I have updated the model to include the source and detector

Running with NaI and ADC setup.

ADC is not calibrated. Running converter in and converter out.

Will swap to He3 detector following these and overlay the source in source out plots from the root files.

  • NaI with converter: Run 7028
