==Assumptions==
The beam spot size was given a diameter of 0.5 based off of the size of a burn mark on a converter that got hot during irradiation.
Electrons are mono energetic.

=Results=
The plots below show the energy distribution for neutrons exiting the converter at three different intervals of their angle w.r.t. the incident electron beam.
The energy spectrum of neutrons from the neutron-induced fission of U235 is shown on each plot, and is normalized to have the same integral flux as the simulated neutrons to facilitate comparison.

The mean and median energy of fission neutrons from U235 is 1.94 MeV and 1.66 MeV, respectively. The mean and median energy of produced neurons are also shown on each plot.

==Assumptions==
The beam spot size was given a diameter of 0.5 based off of the size of a burn mark on a converter that got hot during irradiation.
Electrons are mono energetic.

The plots below show the energy distribution for neutrons exiting the converter at three different intervals of their angle w.r.t. the incident electron beam.
The neutron energy spectrum of the neutron-induced fission of U235 is also in each shown for comparison.

The mean and median energy of fission neutrons from U235 is 1.94 MeV and 1.66 MeV, respectively. The mean and median energy of produced neurons are also shown on each plot.
