PAS Feasibility Preliminary Runs

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
