This condition of uniform flux (or fluence), is also known as CPE. Since the right-hand side of the equation is proportional to the mass density, it may be cancelled out and the solution of the transport equation is, therefore, independent of mass density.

WebIt is common for people looking for neutron generators to confuse yield, flux, and fluence. If you run a neutron generator for one minute, the neutron flux shows how many neutrons pass through a certain area in one second. The neutron fluence shows how many neutrons pass through that area over the course of the entire minute. WebJul 13, 2024 · 1.
