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.
