  • Patent number: 11810682
    Abstract: The object of the invention relates to a neutron absorbing concrete wall (10), which concrete wall (10) has an internal delimiting surface (11a), and an external delimiting surface (11b) on an opposite side to the internal delimiting surface (11a), the essence of which is that it contains a first concrete layer (13a) on the side of the internal delimiting surface (11a), and a second concrete layer (13b) on the side of the external delimiting surface (11b), which first concrete layer (13a) contains at least 0.05 mass % boron-10 isotope (10B), and the second concrete layer (13b) is formed as heavyweight concrete. The object of the invention also relates to a method for creating a neutron radiation absorbing concrete wall (10) that has an internal delimiting surface (11a), and an external delimiting surface (11b) on an opposite side to the internal delimiting surface (11a), the essence of which is a first concrete layer (13a) containing at least 0.

  • Patent number: 11375602
    Abstract: The object of the invention relates to a neutron source, which contains a proton accelerator for producing a proton beam, and a target arranged in the trajectory of the proton beam exiting the proton accelerator for producing a neutron beam, to which the proton beam arrives in long, typically 0.5 ms-3 ms impulses, and contains a moderator-reflector system arranged in the vicinity of the target and serving for producing a moderated neutron beam, which has at least one moderator, and a reflector surrounding the moderator and the target, characterized by that at least one statistical neutron chopper is arranged to protrude into the at least one moderated neutron beam exiting channel that modulates at least one neutron beam intensity according to a random or pseudo-random sample as a function of time with its neutron transmittance ability varying according to such pattern.

  • Patent number: 7214948
    Abstract: A high measuring resolution along with a large irradiation surface and a high beam intensity are required for structural analysis of material according to the small angle neutron scattering measuring technique. However, with known diaphragm collimators, the necessary beam divergence cannot be reached without an unacceptable loss of intensity. The inventive neutron optical component (1) comprises a plurality of successively arranged pinhole diaphragms embodied as grating diaphragms (7), each grating diaphragm (7) comprising a plurality of diaphragm apertures (14). In this way, the neutron beam is divided into individual beams which are each improved in terms of the convergence thereof. Furthermore, the channels defined by the course of the grating diaphragms (7) by means of respectively identically positioned diaphragm apertures (14) are narrowed according to the convergence cone provided by the structure of the measuring instrument.

  • Patent number: 7030397
    Abstract: A neutron-optical component array in which the beam paths of the individual moderators are combined in a concerted manner so as to create a superimposed neutron beam with an effective mean beam direction. The superimposed neutron beam has a multi spectrum composed of the single spectrums of several moderators, whereby a larger spectral width is obtained, making various applications in different neutron energy fields possible. The multi spectrum can be further improved in terms of the intensity thereof and the beam quality by adding further neutron-optical components, particularly in the form of an energy-depending switching super reflector, and by switching between moderators.
