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.
Claims8
A neutron-optical component array for the specific spectral shaping of neutron beams or pulses in a neutron guide or in a radiation hole between a fast neutron source with a plurality of moderators of different structures arrayed closely together for generating slow neutrons of different energy spectra as well as for their radiation in predetermined radiation directions and at least one place of experiment,
- characterized by the fact that
- the radiation directions (CBL, TBL) of the moderators (CNM, TNM) are overlapped directly or by further neutron-optical components (RSM, SSM) in the neutron guide (NGT) or at the place of experiment and that the slow neutrons (CCN, TTN) generated by the moderators (CNM, TNM) of different energy spectra are integrated in common in an overlapping neutron beam (SBL) with a multi spectrum defined by the structure and number of the moderators (CNM, TNM).
