Use of the Response Function in the Analysis of Complex Neutron Spectra

摘要: Neutron time-of-flight spectra with overlapping peaks must be unfolded to yield contributions of individual neutron groups. This requires an accurate knowledge the resolution profile each group. It is also desirable know shape neutrons which were scattered more than once in scatterer, so that corrections for multiple interactions can made. These profiles and shapes are not readily available. We have developed a series measures account these effects our work. monitor target thickness during preparation separate spectrometer; we measure detector accelerator time resolutions different energies using thin use computer codes simulate those factors amenable direct measurement.
