Flux is the presence of a force field in a specified physical medium, or the flow of energy through a surface. In electronics, the term applies to any electrostatic field and any magnetic field.
The neutron flux is a quantity used in nuclear reactor physics corresponding to the total length travelled by all neutrons per unit time and volume,[1] or nearly equivalently number of neutrons travelling through a unit area in unit time.[2] The neutron fluence is defined as the neutron flux integrated over a certain time period.
