Description
The directional sensitivity of two coordinate neutron detector based on 3-$\mu$ m $^{10}$B layer and a wire chamber was studied [1]. In the experiment, the detection of scattered neutrons by the detector was found to be suppressed in comparison with the data from the helium-3 tube counter in the experimental area.
A simulation shows that this phenomena can be explained by two factors acting simultaneously: a neutron flux strong absorption in the $^{10}$B layer which falling at a large angle to the detector plane and the fact that secondary nucleus energy of $^{4}$He or $^{7}$Li is not enough to exceed the energy threshold if nucleus outgoes from the depth of the $^{10}$B layer.
