The SLC Arc magnets are subject to random displacements and field errors resulting in unpredictable transverse displacement of the central trajectory from that of the design. The chosen method of correcting this perturbed trajectory in the SLC Arcs utilizes mechanical movement of the combined function magnets which compose the Arc transport lines. Here we present the results of a recent investigation substantiating the earlier results which led to the adoption of this method.

Eight appendices address the following concentrations of radionuclides: in fish; in frog legs; in crayfish; in sediments; in soil samples; in surface and ground water samples; in water hyacinths; and in beef samples.

The ANSYS superelement model representing the sequential assembly of the ec modules has been used to calculate the maximum forces experienced at any interface between middle modules during assembly. The assembly sequence used was devised by GTM and is referred to as Sequence A. Fig. 1 shows the assembled model and support. One-half symmetry is assumed. The superelement model supported the OCH modules at theta = 56.25 in such a way that the support was allowed to translate freely in the horizontal direction, and rotate freely about the longitudinal (beam) axis. This produces 'worst case' module connecting forces, and is justified given the importance of these connections. The middle modules were supported within the OCH arch only through theta = 56.25. Each middle module interface contained six connection points in the fmite element model through which the forces were transmitted between modules. In presenting the results here, the forces at the three connection locations at the inner radius of each interface were summed, and the largest value found. This was also done for the outer radius. In applying these results to the design of the actual connections, the forces presented here should be divided by the actual number of connection …

We have reexamined the goal of approx.10/sup 13/ cm/sup -3/ central-cell density with end-plugging and reconfirmed its importance as a test of thermal barrier end-plugging performance in either Tara or TMX-U. We conclude that, when all factors are considered including the impact on other programs interlinked with LLNL in the present OFE budget, the lowest cost approach to have a fair chance to meet this goal is to extend Tara operation for the full FY87. Continuation of TMX-U operation in FY87, in addition to the full year of Tara operation, would greatly improve the chance of success. Continuation of the mirror program into FY88 and beyond would be based on an experimental program in TMX-U and Tara at a minimum budget level of $25M/y, with restart of MFTF-B requiring an increase in the national fusion budget. The experimental program to be investigated by TMX-U and Tara would include improvement in the mgnetic geometry (stability, beta limits, and transport), continued plug studies (longer pulse length, impurities, drift pumping, and ECH efficiency), and transport studies (chi/sub e/, fueling, and halo formation).

In 1984, the spillway of Steed Pond fed by Tims Branch collapsed and the pond slowly drained. Consideration was given to leaving the pond dry, but concern was expressed that the uranium accumulated in the sediments from the 300 Area discharges to Tims Branch might be eroded and transported to Upper Three Runs Creek. This study shows that the measured amount of sediment transported to Upper Three Runs Creek from Tims Branch No. 5, about two miles below Steed Pond, was about the same as in past years before the spillway collapsed. What little erosion that has occurred in the exposed sediments will be even less in the future with the revegetation of the exposed sediments. These results indicate that Steed Pond could be left in its present condition (dry) without affecting suspended solids concentrations and associated uranium concentrations in Upper Three Runs Creek. 7 figs.

During the first few months of operation of our soft x-ray spectrometer at the NSLS, we have measured the L emission spectrum for three classes of aluminum alloys: dilute aluminum-magnesium alloys to extend the Al-Mg system to the impurity limit; a 50-50 alloy of aluminum-lithium to characterize the band structure of bulk samples of this potential battery electrolite; and the icosahedral and normal Al-Mn alloys to see if the two phases had measurably different density of states which have been predicted. All spectra shown are produced when core holes generated by energetic electrons or photons are filled by radiative transitions from conduction band states. Dipole selection rules govern the transitions. Thus, K spectra provide a measure of the p-symmetic partial density of states (DOS) near the atom. Similarly, L spectra produced by transitions to p-core holes map the s and d symmetric DOS in the vicinity of the atom with the core hole.

During isothermal multicomponent diffusion, interdiffusion fluxes of individual components can go to zero at zero-flux planes (ZFP) and exhibit flux reversals from one side to the other of such planes. Interdiffusion fluxes as well as the locations and compositions of ZFPs for components are determined directly from the concentration profiles of diffusion couples without the need for prior knowledge of interdiffusion coefficients. The development and identification of ZFPs is reviewed with the aid of single phase and two-phase diffusion couples investigated in the Cu-Ni-Zn system at 775/sup 0/C. ZFP locations in the diffusion zone nearly correspond to sections where the activity of a component is the same as its activity in either of the terminal alloys of a couple. Path slopes at ZFPs are uniquely dictated by the atomic mobility and thermodynamic data for the components. Discontinuous flux reversals for the components can also occur at interfaces in multiphase couples. Identification of ZFPs is also presented for diffusion in the Cu-Ni-Zn-Mn quaternary system. Analytical representation of diffusion paths for both ternary and quaternary diffusion couples is presented with the aid of characteristic path parameters.
