A numerical model, based on multigroup diffusion theory, was developed to predict the neutron flux distribution in a neutron probe and surrounding soil.
While the time-averaged neutron flux at LENS is expected to be comparable to that of the IPNS, the gamma background is expected to be relatively low.
If we are able to shift the peak of the cold neutron flux down to the [approximately equal to]1 meV range, then the development of ultra-cold neutron sources based on solid oxygen or superfluid [.
Ultimately, the FP12 neutron flux will limit the precision in [A.
Our test measurements [7] have shown that expectations of the available neutron flux from the upgraded LANSCE facility were too optimistic by almost a factor of four, with roughly equal contributions from reduced moderator brightness and reduced production beam current.
Therefore, the nn scattering intensity is proportional to the square of the neutron flux density, while the background intensity depends linearly on the flux density.
The situation is most favorable at pulsed neutron sources, where the thermal neutron flux density can be very high.
The relative distribution of the neutron flux along the axis of the through-channel was also obtained.
We measure the neutron flux through a slit between a mirror and a scatterer versus the slit size.
hor]) is the neutron flux through the slit, [alpha] is the coefficient responsible for a finite scatterer efficiency and for the approximations used in the model, [[beta].
The dependence of the neutron flux through a slit between a mirror and a scatterer versus the slit size was measured in an analogous way to that in Ref.
For special purposes, irradiations can be performed in the thermal column (in which the ratio of thermal to fast neutrons is 1000) or in the reactor core (at a neutron flux of 4 X [10.
