Macroscopic transport cross section from macroscopic scattering cross section¶

Macroscopic transport cross section can be found using the macroscopic scattering cross section and the averaged cosine of the scattering angle.

Symbol:: Sigma_s
Latex:: \(\sigma_\text{s}\)
Dimension:: 1/length

average_scattering_angle_cosine¶: Average of the cosine of the angle at which neutrons are scattered in the medium in the lab system.

Symbol:: mu
Latex:: \(\mu\)
Dimension:: dimensionless

macroscopic_transport_cross_section¶: macroscopic_cross_section of neutron transport (i.e. the movement of neutrons through the material).

Symbol:: Sigma_tr
Latex:: \(\Sigma_\text{tr}\)
Dimension:: 1/length

law¶

Sigma_tr = Sigma_s * (1 - mu)

Latex:: \[\Sigma_\text{tr} = \sigma_\text{s} \left(1 - \mu\right)\]
