general setup
fitting the collimator size into the hole through the concrete wall
I can express the distance as function of collimator size and electron beam energy E:
To fit the collimator size into the hole through the concrete wall with radius R = 8.73 cm we need to solve equation:
1) Assuming the collimator diameter is :
2) Assuming the collimator diameter is :
3) Assuming the collimator diameter is :
4) for arbitrary collimator size :
All energy under this line is good to run experiment for condition above
GH = 5.08 cm condition
1) assuming the collimator diameter is
2) assuming the collimator diameter is
3) assuming the collimator diameter is
4) for arbitrary collimator size :
All energy under this line is good to run experiment for condition above
both conditions above are together
All energy under this linse is good to run experiment for both conditions above
