Dispersive effects of transverse displacements of SLC Arc magnets

Description: 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.

Zero-flux planes, flux reversals and diffusion paths in ternary and quaternary diffusion

Description: 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 … more

Proposed tandem mirror research program for FY87 presented to the MFAC subcommittee on mirror research, July 8-9, 1986

Description: 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,… more

Sediment transport studies in Tims Branch. [Drained after spillway collapse]

Description: 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 y… more

Forces on the Middle EC Module Connections Resulting From Assembly Sequence A

Description: 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 horizont… more

Soft x-ray emission studies of several aluminum alloys

Description: 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 … more
