MECHANICAL NEUTRON BEAM FILTER WITH THE TIME FOCUS Russian patent published in 2021 - IPC G21K1/04 H05H3/00 

FIELD: nuclear physics.

SUBSTANCE: invention relates to nuclear physics and namely to neutron beam production with the help of a chopper. The mechanical neutron beam filter with the time focus is a cylinder with the ability to rotate around its axis. Thin plates of neutron-absorbing material are attached to the outer walls of the cylinder. Individual channels formed by the plates made of neutron-absorbing material expand linearly along the cylinder axis along the direction of the beam at a certain angle to the cylinder axis. There is a layer of neutron absorbing material on the area of ​​the cylinder surface where there are no channels. The thickness of the layer is greater than or equal to the height of the channels.

EFFECT: invention increases the resolution of the device and improves the quality of the acquired spectra.
