Beam tests of phosphorescent screens

Description: Twelve phosphorescent screens were beam tested for linearity, uniformity, low radiation damage and a suitable emitted wavelength for use with television cameras. One screen was chosen for the construction of several intercepting profile monitors which were used during the SLC Ten Sector Tests to measure the emittance and wakefield effects of a damped electron beam.

A recommendation: How to build lasting consensus on a national energy strategy

Description: The objective of the Consensus Building process for a national energy strategy would be to generate several concrete products, including: (1) An inventory of possible packages which could represent acceptable energy strategies for most key constituencies in developing a fair, efficient wise, and sustainable national energy policy; (2) An inventory of strategic dead ends and policy positions that could generate fierce opposition from specific stakeholding groups if they emerge as part of the eventual strategy, absent compensating trade offs; and, (3) An inventor of the interests and assumptions of the many opposing constituencies. The process would be a sophisticated proving ground where collaborative problem solving techniques could be applied and evaluated. This report in the American Energy Assurance Council's 12-step recommendation for consensus building. They recommend an eight-month timeframe for this project, although they recognize that many interested parties may perceive this as too long. If a shorter timeframe is required, these 12 steps could be time compressed and still produce meaningful results.

Solar and geothermal energy utilization n SF-2: a sensitivity analysis

Description: A sensitivity analysis was conducted of the utilization levels for Solar, Geothermal, and Advanced Energy Systems (ASGA) technologies during the 1985-2000 time period. In particular, the sensitivity of the utilization levels was tested with respet to both analytical techniques and to specific parameter assumptions. The sensitivity to analytical techniques was examined insofar as certain criteria were examined to elucidate their importance in determining the level of use of the ASGA technologies. The criteria incorporated consideration of such factors as total cost of the energy system, environmental impacts, and resource use patterns. The parameter assumptions studied included costs of ASGA costs of ASGA technologies, costs of non-renewable resources, and limitations on the use of technologies and resources. (MHR)

Water-cooled U-tube grids for continuously operated neutral-beam injectors

Description: A design for water-cooled extractor grids for long-pulse and continuously operated ion sources for neutral-beam injectors is described. The most serious design problem encountered is that of minimizing the thermal deformation (bowing) of these slender grid rails, which have typical overall spans of 150 mm and diameters on the order of 1 mm. A unique U-tube design is proposed that offers the possibility of keeping the thermal bowing down to about 0.05 mm (about 2.0 mils). However, the design requires high-velocity cooling water at a Reynolds number of about 3 x 10/sup 4/ and an inlet pressure on the order of 4.67 x 10/sup 6/ Pa (677 psia) in order to keep the axial and circumferential temperature differences small enough to achieve the desired small thermal bowing. It appears possible to fabricate and assemble these U-tube grids out of molybdenum with high precision and with a reasonably small number of brazes.

US nuclear weapons policy

Description: We are closing chapter one'' of the nuclear age. Whatever happens to the Soviet Union and to Europe, some of the major determinants of nuclear policy will not be what they have been for the last forty-five years. Part of the task for US nuclear weapons policy is to adapt its nuclear forces and the oganizations managing them to the present, highly uncertain, but not urgently competitive situation between the US and the Soviet Union. Containment is no longer the appropriate watchword. Stabilization in the face of uncertainty, a more complicated and politically less readily communicable goal, may come closer. A second and more difficult part of the task is to deal with what may be the greatest potential source of danger to come out of the end of the cold war: the breakup of some of the cooperative institutions that managed the nuclear threat and were created by the cold war. These cooperative institutions, principally the North Atlantic Treaty Organization (NATO), the Warsaw Pact, the US-Japan alliance, were not created specifically to manage the nuclear threat, but manage it they did. A third task for nuclear weapons policy is that of dealing with nuclear proliferation under modern conditions when the technologies needed to field effective nuclear weapons systems and their command and control apparatus are ever more widely available, and the leverage over some potential proliferators, which stemmed from superpower military support, is likely to be on the wane. This paper will make some suggestions regarding these tasks, bearing in mind that the unsettled nature of that part of the world most likely to become involved in nuclear weapons decisions today must make any suggestions tentative and the allowance for surprise more than usually important.

Cleaning of aluminum alloy 5083. [For welding]

Description: The purpose of this investigation was to evaluate several different cleaning procedures on welds with very low heat inputs. The study evaluated the Oak Ridge Y-12 Plant's chemical cleaning, another type of chemical cleaning, ion cleaning, and diamond-machined cleaning. The results showed that the diamond-machining process provides better weld joint surfaces and sound welds with minimum oxide inclusion and porosity.

Model of current enhancement at high pressure

Description: A model is proposed to account for the phenomenon of net current enhancement at high pressures recently observed on the Experimental Test Accelerator. The proposed mechanism involves energetic secondary electrons (delta rays) which are pushed forward by the self-magnetic field of the electron beam. For high current beams, the forward delta ray current can build up to a significant fraction of the beam current. Analytic calculations of the steady-state solution as well as the rate of buildup of the delta ray current are presented in this paper. In addition, numerical results from a nonlocal Boltzmann code, NUTS, are presented. The analytic and numerical results have many features which are in qualitative agreement with the experiments, but quantitative discrepancies still exist.
