Notes for the July 11th, 2008 Meeting

[math]\frac {m}{e}[/math] = we'll have 2.5"

[math]\frac {2.5}{x}[/math] = tan(1.95)

radiator distance - collimator

x = 73.4" = 186.5 cm

radiator is 73.4" - 48" upstream of the wall

Something someone needs to do:

Look up which has the highest neutron production energy thresh hold: Cu, Zn, Ni

2 p _n cos θ = 15 MeV

2 sqrt(p_n ² + m _n ²) = 15 MeV = m _d
