Neutron Flux Density
For most applications, a higher neutron flux is always better (since it reduces the time required to conduct the experiment, acquire the image, etc.). Amateur fusion devices, like the fusor, generate only about 300 000 neutrons per second. Commercial fusor devices can generate on the order of 109 neutrons per second, which corresponds to a usable flux of less than 105 n/(cm² s). Large neutron beamlines around the world achieve much greater flux. Reactor-based sources now produce 1015 n/(cm² s), and spallation sources generate greater than 1017 n/(cm² s).

Famous quotes containing the word flux:
“Sense is a line, the mind is a circle. Sense is like a line which is the flux of a point running out from itself, but intellect like a circle that keeps within itself.”
—Ralph J. Cudworth (1617–1688)
