Gamma Count Rates

Been spending a bunch of time in Gamma Town.  It's nice, you don't have to interact with anybody*.  Shown below is comparing results to simulated values from the total interactions. 

Source of all errors

Alright, so not perfect. But hey, I'm gonna take it.  It explains a lot of the problems we have been having; doubling the distance about doubles the counts.   I think at the father distances photons bouncing around off the table and the lab might also be a little bit an issue. It is also unsettling how the simulated and calculated cross each other.  Now the problem is going to make sure that we can have a repeatable geometry; so maybe we want to place it around 6" away, where 1/2" in each direction only changes the count rate by 12%.  At 1/4", moving the sample by 1/4" changes the counts by 30%.

*Groan worthy, but I'm proud of it.  Gamma's are photons, and are characterized by a probability of interaction, not like electrons which are always experiencing E&M fields.
