A companion star within 0.8 pc of the Sun has been postulated to explain a possible 26 Myr periodicity in mass extinctions of species on the Earth. Such a star would already be catalogued in the Yale Bright Star catalogue unless it is fainter than m/sub nu/ = 6.5; this limits the possible stellar types for an unseen companion to red dwarfs, brown dwarfs, or compact objects. Red dwarfs account for about 75% of these possible stars. We describe here the design and development of an astrometric search for a nearby red dwarf companion with a six-month peak-to-peak parallax of greater than or equal to2.5 arcseconds. We are measuring the parallax of 2770 candidate faint red stars selected from the Dearborn Observatory catalogue. An automated 30-inch telescope and CCD camera system collect digitized images of the candidate stars, along with a 13' x 16' surrounding field of background stars. Second-epoch images, taken a few months later, are registered to the first epoch images using the background stars as fiducials. An apparent motion, m/sub a/, of the candidate stars is found to a precision of sigma/sub m//sub a/ approx. = 0.08 pixel approx. = 0.2 arcseconds for fields with N/sub fiducial/ …

This report addresses two broad aspects of the behaviors of hydrodynamic flows, resulting from laser heated, exploding foils. In Part I, various aspects of the similarity solutions are considered, whereas in Part II the stability of the flows at early times are examined, before the similarity solutions are established. 5 refs., 3 figs.

Accelerator mass spectrometry in tandem Van de Graaff accelerators has proven successful for radioisotope dating small samples. We are developing a 20 cm diameter 30 to 40 keV cyclotron dedicated to high-sensitivity radioisotope dating, initially for /sup 14/C. At this energy, range and dE/dx methods of particle identification are impossible. Thus arises the difficult problem of reliably detecting 30 to 40 keV /sup 14/C at 10/sup -2/ counts/sec in the high background environment of the cyclotron, where lower energy ions, electrons, and photons bombard the detector at much higher rates. We have developed and tested an inexpensive, generally useful ion detector that allows dark-count rates below 10/sup -4/ counts/sec and excellent background suppression. With the cyclotron tuned near the /sup 13/CH background peak, to the frequency for /sup 14/C, the detector suppresses the background to 6 x 10/sup -4/ counts/sec. For each /sup 14/C ion the detectors grazing-incidence Al/sub 2/O/sub 3/ conversion dynode emits about 20 secondary electrons, which are independently multiplied in separate pores of a microchannel plate. The output signal is proportional to the number of secondary electrons, allowing pulse-height discrimination of background. We have successfully tested the detector with positive /sup 12/C, /sup 23/Na, /sup 39/K, /sup …

This report describes the design and construction of five spoiler magnets installed in the secondary beamline to the Meson West Experimental Hall. Tests have been performed to measure the magnetic field in the steel as a function of the excitation current. B versus I curves for each spoiler are included. The leakage field in the beam pipe through the spoiler steel was too high. Magnetic shield and reduced excitation are used to lower this leakage field to acceptable levels.

The Department of Energy/Morgantown Energy Technology Center (DOE/METC) has initiated research on the disposal of solid wastes from advanced coal processes. The objective of this research is to develop information to be used by private industry and government agencies for planning waste disposal practices associated with advanced coal processes. To accomplish this objective. DOE has contracted Radian Corporation and the North Dakota Mining and Minerals Resources Research Institute (MMRRI) to design, construct and monitor a limited number of field disposal tests with select advanced coal process wastes. These field tests will be monitored aver a three year period with the emphasis on collecting data on the field disposal behavior of these wastes. Objectives for the third quarter (and into October) were as follows: formalize the basis for the test designs; select design options; prepare a draft of the Test Design Manual; and initiate work on the Test Procedures Manual. The accomplishments under each task are described.

Geothermal effluent from the Oregon Institute of Technology campus and Merle West Medical Center has been discharged to an open drainage ditch adjacent to the City's College Industrial Park since 1964. Over the past few years there has been increasing concern for conservation and preservation of the geothermal aquifers in Klamath Falls, Oregon. An effective way of improving the energy utilization is to cascade the approximately 130/sup 0/F effluent for heating buildings in the industrial park and disposal of the effluent in an existing injection well. An aquifer stress test was performed using the 1500 foot well in the industrial park. Based on the specific capacity, data indicate that the well is capable of accepting an injection rate of at least 700 gpm of the thermal effluent. A plume of degraded water will develop down-gradient of the well. However, the plume is expected to bypass nearby water supply wells and will have no impact on OIT and MWMC space heating wells.

The objectives of this project have been: (1) Investigate the possibility of chemical etching of GSGG crystal slabs to obtain increased strength. (2) Design and construct a simplified mold assembly for casting cladding glass to the edges of crystal slabs of different dimensions. (3) Conduct casting experiments to evaluate the redesigned mold assembly and to determine stresses as function of thermal expansion coefficient of cladding glass. (4) Clad larger sizes of GGG slabs as they become available. These tasks have been achieved. Chemical etching of GSGG slabs does not appear possible with any other acid than H/sub 3/PO/sub 4/ at temperatures above 300/sup 0/C. A mold assembly has been constructed which allowed casting cladding glass around the edges of the largest GGG slabs available (10 x 20 x 160 mm) without causing breakage through the annealing step.

An analytical attempt is made to estimate the perturbations of eta-functions after orbit correction of the SLC arcs. Emphasis is on the effects caused by the orbit errors created by misalignments. It is shown that the 'non-dispersive' property of a 'magnet mover' is not true whenever the vertical off-energy function is non-zero. The north arc is used as an example for numerical calculation.

This report is developed as part of the Fermilab Central Computing Facility Project Title II Design Documentation Update under the provisions of DOE Document 6430.1, Chapter XIII-21, Section 14, paragraph a. As such, it concentrates primarily on HVAC mechanical systems design optimization and cost analysis and should be considered as a supplement to the Title I Design Report date March 1986 wherein energy related issues are discussed pertaining to building envelope and orientation as well as electrical systems design.

The goal of the Argonne Positive Ion Injector project is to replace the ATLAS tandem injector with a facility which will increase the beam currents presently available by a factor of 100 and to make available at ATLAS essentially all beams including uranium. The beam quality expected from the facility will be at least as good as that of the tandem based ATLAS. The project combines two relatively new technologies - the electron cyclotron resonance ion source, which provides high charge state ions at microampere currents, and RF superconductivity which has been shown to be capable of generating accelerating fields as high as 10 MV/m, resulting in an essentially new method of acceleration for low-energy heavy ions.

This project was designed to investigate the properties of the rare-earth phosphate glasses CeO{sub 2}-P{sub 2}O{sub 5} and Pr{sub 2}O{sub 3}-P{sub 2}O{sub 5} for potential use as radioactive waste glasses. The research involved determination of the glass-forming region, loading capacity, and optimum processing parameters of the glasses. Structural studies of the unloaded host glasses and glasses loaded with simulated waste elements were to be done using Raman, infrared and infrared reflection spectroscopy. Leach testing and spectroscopic studies of the corroded surfaces were also to be performed.

In this report is examined the possibility of polarized proton in RHIC collider. The issues needed for the future study is also discussed. With the improved source and AGS booster, its is expected that the luminosity for polarized beam could be 0.4*10^32/cm^2/sec at energy of 250 Gev in RHIC. There we need 4 snakes and 4 spin rotators in the collider.
