[en] The recommendations by the various groups regarding instrumentation are summarized. Almost all the instruments have been recommended by more than one workshop group. This indicates that a multidisciplinary group should be involved in detailed planning and design for these instruments. To judge whether the preliminary plans for beam facilities are consistent with these workshop recommendations, it is assumed that three instruments can be installed on a guide and one instrument on a horizontal or slant beam tube

[en] The Center for Neutron Research (CNR) has been proposed in response to the needs - neutron flux, spectrum, and experimental facilities - that have been identified through workshops, studies, and discussions by the neutron-scattering, isotope, and materials irradiation research communities. The CNR is a major new experimental facility consisting of a reactor-based steady state neutron source of unprecedented flux, together with extensive facilities and instruments for neutron scattering, isotope production, materials irradiation, and other areas of research

[en] An attitude of cooperation rather than competition should and does exist between large and small reactor centers with regard to neutron scattering. Two areas of clear mutual interest are the development of user communities and the development of improved instrumentation. The current situation in Europe and the United States is examined and contrasted for these two areas. A recommendation is advanced for increased cooperation in the US between large and small reactor centers in the education and training of neutron scattering users

[en] The use of magnetic fields in the general area of neutron scattering is briefly surveyed, and some specific areas of research are identified which would benefit by the availability of higher fields. Since most of the past work combining neutron scattering and high magnetic fields has involved the polarized neutron technique, a description of this technique is presented along with a discussion of experimental errors produced by the magnetic field. The current status of polarized-beam research in four areas is reviewed: induced form factors in transition metals, mixed-valence systems, Kondo systems and complicated paramagnets

[en] In an effort to foresee the future health of neutron scattering, a survey of plans to upgrade reactors and associated experimental facilities was undertaken. The results indicate that we are now entering a period characterized by a substantial reinvestment in reactor sources and expansion in the number of neutron scattering instruments. For the group of institutions participating in this survey there will be a total investment in improved sources and experimental facilities of $500 M to $1,000 M over the next decade. This investment will result in a 30 to 40% increase in the total power of research reactors and an increase of 30 to 50% in the number of neutron scattering instruments. It is therefore reasonable to anticipate an approximate doubling in the number of reactor neutrons incident on samples in the mid 90s compared to the present

[en] This paper assumes a large D₂O reflector equipped with cold source(s), a hot source, and with a peak thermal flux in the reflector of phi₀ = 5 x 10¹⁵ ncm^-2 sec^-1. The flux distributions for thermal, cold, and hot beams are estimated. The equations required to calculate neutron intensities delivered by beam tubes and guides are summarized and some expected intensities are given for the assumed 5 x 10¹⁵ reactor. In addition, the equations needed to calculate monochromatic intensities delivered to the sample by a crystal monochromator are given

[en] We have completed an engineering feasibility study of a major modification of the HFIR facility and are now beginning a similar study of an entirely new facility. The design of the reactor itself is common to both options. In this paper, a general description of the modified HFIR is presented with some indications of the additional facilities that might be available in an entirely new facility

[en] The purpose of the Workshop on Instrumentation for the Advanced High-Flux Reactor, held on May 30, 1984, at the Oak Ridge National Laborattory, was two-fold: to announce to the scientific community that ORNL has begun a serious effort to design and construct the world's best research reactor, and to solicit help from the scientific community in planning the experimental facilities for this reactor. There were 93 participants at the workshop. We are grateful to the visiting scientists for their enthusiasm and interest in the reactor project. Our goal is to produce a reactor with a peak thermal flux in a large D₂O reflector of 5 x 10¹⁵ n/cm² s. This would allow the installation of unsurpassed facilities for neutron beam research. At the same time, the design will provide facilities for isotope production and materials irradiation which are significantly improved over those now available at ORNL. This workshop focussed on neutron beam facilities; the input from the isotope and materials irradiation communities will be solicited separately. The reactor project enjoys the full support of ORNL management; the present activities are financed by a grant of $663,000 from the Director's R and D Fund. However, we realize that the success of the project, both in realization and in use of the reactor, depends on the support and imagination of a broad segment of the scientific community. This is more a national project than an ORNL project. The reactor would be operated as a national user facility, open to any research proposal with high scientific merit. It is therefore important that we maintain a continuing dialogue with outside scientists who will be the eventual users of the reactor and the neutron beam facilities. The workshop was the first step in establishing this dialogue; we anticipate further workshops as the project continues
