The beam-dump kicker magnets are located in the final focus region and, in conjunction with septum magnets, extract the beams after they have passed the interaction point (IP) and direct them to their respective dumps. Two schemes for these kickers have been under consideration; ferrite transmission line magnets utilizing technology common with damping rings and positron target kickers, and current loop magnets which are possible only for the dump kickers, where the rise time of the magnetic pulse can be comparatively longer; approximately 400 nanoseconds as compared with 50 nanoseconds for the others. A prototype ferrite kicker has been built and is undergoing tests. Since the current loop requires lower voltage and power plus some additional savings in cost, we decided to build and test a prototype. This note describes in detail an optimized design for the current loop magnets and their associated pulse circuitry.

The Energy Policy and Conservation Act (EPCA! (P.L. 94-163), as amended by the National Energy Conservation Policy Act (NEPCA) (P.L. 95-619) , requires that energy efficiency standards be established for each of 13 classes of appliances that are major consumers of energy. NEPCA stipulates that such standards "be designed to achieve the maximum improvement in energy efficiency which the Secretary [of Energ'y] determines is technologically feasible and economically justified." The Department of Energy ' announced proposed standards for 8 of the 13 classes of appliances in June 1980 and initiated public hearings on them prior to final promulgation. In January 1981, the DOE suspended this process; after re-studying the proposed standards, it announced in April 1982 a finding that no standards are economically justified.

This report was originally written as part of the Physics Analysis Document for the End-Loss Ion Energy Spectrometer for MFTF. In the course of that analysis, we investigated many possibilities. We have decided that this survey of the different types of analyzers and detectors could be of use to others facing a similar choice. The Appendix covers a formalism developed for finding the trajectories of charged particles in constant, uniform, but otherwise arbitrary electric and magnetic fields.

A print-out (filename, Lebout Output, dated 07/14/83) was obtained which contains the LTR quad and bend magnet specifications actually used for final alignment. The format includes tooling ball data plus coordinates, 'X' 'Y' 'Z' in the SBO grid, defining the mechanical centers of the magnets.

In-tank sludge processing will reduce the scope and cost of the Defense Waste Processing Facility (DWPF). A full-scale demonstration of this process has recently been completed. This test established that aluminum dissolution and sludge washing can be accomplished in a high level waste tank. The Savannah River Laboratory had the responsibility of characterizing (physically and chemically) samples from the demonstration. This memo presents physical properties, aluminum concentration, and supernate inhibitor levels.

Ultimate strength and shear wave velocity of dry, 50% saturated, and saturated Paintbrush tuff samples from the Nevada Test Site (NTS) are measured as a function of pressure up to 400 MPa. A linear relationship exists between the ultimate strength (tau) and shear modulus (..mu..) for the dry tuff at pressures from 0.1 to 20 MPa and from 100 to 300 MPa, with values of d tau/d..mu..; of about 1.25 x 10/sup -2/ and 2.6 x 10/sup -2/, respectively. At pressures between 20 and 100 MPa a linear relationship also exists with a much greater value of d tau/d..mu.., of about 9.9 x 10/sup -2/. For the half-saturated tuff, under undrained testing conditions, a similar linear relationship exists at pressures up to 20 MPa. At pressures between 20 and 300 MPa the data of the partially saturated tuff have too much scattering to deduce a meaningful relation. No such correlation can be found for the saturated tuff sample under undrained testing conditions. If similar relations could be found for other rock types and under other controlled experimental coditions, such as at a fixed pore fluid pressure (drained test) or temperature, then the results would be very valuable for the estimation …

The Nevada Nuclear Waste Storage Investigations (NNWSI) Waste Package project is part of the US Department of Energy`s Civilian Radioactive Waste Management (CRWM) Program. The NNWSI project is working towards the development of multibarriered packages for the disposal of spent fuel and high-level waste in tuff in the unsaturated zone at Yucca Mountain at the Nevada Test Site (NTS). The final engineered barrier system design may be composed of a waste form, canister, overpack, borehole liner, packing, and the near field host rock, or some combination thereof. Lawrence Livermore National Laboratory`s (LLNL) role is to design, model, and test the waste package subsystem for the tuff repository. At the present stage of development of the nuclear waste management program at LLNL, the detailed requirements for the waste package design are not yet firmly established. In spite of these uncertainties as to the detailed package requirements, we have begun the conceptual design stage. By conceptual design, we mean design based on our best assessment of present and future regulatory requirements. We anticipate that changes will occur as the detailed requirements for waste package design are finalized. 17 references, 4 figures, 10 tables.

The following experimental results are shown: (1) uniformity of AR coatings on Optosil and Sprasil provided by LLNL; (2) relation between cleaning methods and properties of AR coatings; (3) baking and sintering conditions of gel-derived films; (4) heat treatment of AR coating in O/sub 2/ flow.

Successful collider operation requires that ground motion not exceed certain tolerances. In this note it is pointed out that on occasion these tolerances are exceeded. The frequency of such events and their amplitudes, measured as a function of time of day, have been measured. An examination of the data leads one to conclude that most events are of cultural (i.e., man-made) origin. 2 references, 20 figures.
