= we'll have 2.5"
= 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
KE = 5.3 MeV
β = .1
θ = 85.6° -> Means that since they're moving forward, the angles will be pushed forward to be less than 90°.
KE n fission = 1 MeV -> fission neutrons
V = .05c
-> 25 nsec/ft
Beam pulse
