Neutron flux

The neutron flux value is calculated as the neutron density (n) multiplied by neutron velocity (v), where n is the number of neutrons per cubic centimeter (expressed as neutrons/cm3) and v is the distance the neutrons travel in 1 second The neutron flux is the product of the neutron density and the neutron speed. Assuming that all the neutrons are travelling at the same speed, equal to the average speed, cn, the reactor flux averaged over the complete core, xave, neutrons/m 2 /s will be the product: (21.33) χ a v e = n c n The neutron flux, which is the number of neutrons crossing through some arbitrary cross-sectional unit area in all directions per unit time, is a scalar quantity.

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 thermal neutron velocity/energy (2 2 E 1 m v K = n) distribution is Maxwellian. The number of neutrons of energy E per unit energy interval, N(E), and the number of neutrons of velocity v per unit velocity interval, N(v), can be expressed in terms of the neutron energy: E e E kT kT N N E dE dN / 3/2 0 0 2 = ( ) = − π π (1) or the neutron velocity: e mv kT kT m v N N v dv dN /2 Svensk översättning av 'neutron flux' - engelskt-svenskt lexikon med många fler översättningar från engelska till svenska gratis online. Free neutrons, while not directly ionizing atoms, cause ionizing radiation.

Neutron flux






The neutron flux, φ, is a scalar quantity used in nuclear physics and nuclear reactor physics. It is the total length travelled by all free neutrons per unit time and volume. Equivalently, it can be defined as the number of neutrons travelling through a small sphere of radius in a time interval, divided by
