Forces on the conductors of the Arc AG Magnet (open access)

Forces on the conductors of the Arc AG Magnet

In the evaluation of the design of the support system for the Arc AG Magnets, factors which could deform or move the magnet have to be considered. Typically they are the ground movements, temperature effects, water vibrations, magnetic forces on the magnet and coil, and accidental human or equipment impacts. This note calculates the magnetic forces on the conductors at an excitation for a 50 GeV beam. It is found that the force is not negligible; therefore, a method to restrict the movement of the conductors should be introduced.

Radionuclide Inventory and Distribution Program: the Galileo area (open access)

Radionuclide Inventory and Distribution Program: the Galileo area

The Galileo area is the first region of the Nevada Test Site to be surveyed by the Radionuclide Inventory and Distribution Program (RIDP). This report describes in detail the use of soil sampling and in situ spectrometry to estimate radionuclide activities at selected sampling locations; the descriptions of these methods will be used as a reference for future RIDP reports. The data collected at Galileo were analyzed by kriging and the polygons of influence method to estimate the total inventory and the distribution of six man-made radionuclides. The results of the different statistical methods agree fairly well, although the data did not give very good estimates of the variogram for kriging, and further study showed the results of kriging to be highly dependent on the variogram parameters. The results also showed that in situ spectrometry gives better estimates of radionuclide activity than soil sampling, which tends to miss highly radioactive particles associated with vegetation. 18 references, 28 figures, 11 tables.

New magic angle bumps and magic translation bumps (open access)

New magic angle bumps and magic translation bumps

SLC beams of opposite charge can be transversely deflected in the same direction by RF fields in the accelerating cavities caused by girder tilts, coupler-asymmetries, or manufacturing errors. A symmetric deflection can be corrected by a magic angle bump if the deflection is located adjacent to one of the linac quadrupoles. However, if the deflection is located between quadrupoles, two magic angle bumps or a magic angle bump and a magic translation bump are needed for the correction. Several examples of translation bumps are included. A new magic angle bump is also presented which is longitudinally compressed and has significantly reduced particle excursions. Finally, if new correctors are added midway along the girders so that the number of correctors are doubled, then the longitudinal extent and the maximum particle excursion of these new magic bumps can be further reduced.

Individual Retirement Accounts (IRAs) (open access)

Individual Retirement Accounts (IRAs)

Recent changes in the Nation's tax laws have made Individual Retirement Accounts available to many people previously excluded. This report provides general information on IRAs including material explaining these recent changes and their consequences.

LONG-TERM EFFECTS OF WASTE SOLUTIONS ON CONCRETE AND REINFORCING STEEL (open access)

LONG-TERM EFFECTS OF WASTE SOLUTIONS ON CONCRETE AND REINFORCING STEEL

This report has been prepared for the In Situ Waste Disposal Program Tank Assessment Task (WG-11) as part of an investigation to evaluate the long-term performance of waste storage tanks at the Hanford Site. This report, prepared by the Portland Cement Association, presents the results of four years of concrete degradation studies which exposed concrete and reinforcing steel, under load and at 180 F, to simulated double-shell slurry, simulated salt cake solution, and a control solution. Exposure length varied from 3 months to 36 months. In all cases, examination of the concrete and reinforcing steel at the end of the exposure indicated there was no attack, i.e., no evidence of rusting, cracking, disruption of mill scale or loss of strength. Radioactive waste resulting from the chemical processing of reactor fuel for recovery of special nuclear materials (primarily plutonium), has been accumulating at the Hanford Site since 1944. The defense waste is currently being stored in underground waste tanks and in capsules stored in water basins. Current U.S. Department of Energy (DOE) strategy is to emphasize development and implementation of technology for removal, solidification, and final disposition of defense waste at the Savannah River Site first, then at the Hanford Site. …
