Beam-dump kicker magnets

Description: 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 pu… more

Evaluation of ion-energy spectrometers for use on MFTF

Description: 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.

Correlation of ultrasonic velocity and rock strength

Description: 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 relati… more

Demonstration of in-tank sludge processing: Part 1, Aluminum dissolution, sludge washing and settling results

Description: 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 superna… more

Preliminary study of the positions of elements in LTR

Description: 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.

Ground motion: frequency of occurrence versus amplitude of disturbing transient events

Description: 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.

Containment barrier metals for high-level waste packages in a Tuff repository

Description: 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, p… more

Energy Efficiency Standards for Appliances: Are They Needed?

Description: 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 E… more
