Abstract
A compact and small size multichannel collimator for neutrons with energies up to 50 keV is provided. The collimator has a multichannel structure composed of collimating channels (in air, vacuum or in the non-interacting atmosphere of Helium-4) alternating with “full” channels made with absorbent materials for slow neutrons. The geometry of the individual collimating and absorbing channels can be arbitrary. The geometry with channels of square section, such as to create a perfect checkerboard, is preferred from the point of view of ease of construction.
Claims19
A collimator for neutrons, wherein
- the collimator has a shape of a regular solid with a square section of a side Q and comprises a front end face and a posterior end face, wherein the front end face and the posterior end face are parallel and spaced apart by a length L, and a direction of collimation corresponds to a longitudinal axis of the collimator,
- the collimator comprises a plurality of identical units in the form of channels with a longitudinal axis parallel to the longitudinal axis of the collimator, wherein absorbing channels made of absorbent material for neutrons and collimating channels alternate with each other, and the absorbing channels and the collimating channels each have a square section of a side d and are organized according to a regular checkerboard arrangement, the absorbing channels surround the collimating channels, and the absorbing channels are identical to the collimating channels.
