A laboratory-scale experimental device having an outside diameter of 1.2 m has been designed to test the idea of electrostatic end plugging of an open-ended magnetic-field configuration. The configuration is a toroidal quadrupole having four very thin (less than 1-mm-thick) line cusps produced by four circular copper coils. Iron is used to concentrate the magnetic flux density to 2.0 T; without the use of iron, the power consumption, which is about 1 MW, would be about 25 times higher. The use of iron also produces a precisely known magnetic field and allows good access for diagnostics and pumping. Iron is also used for both the flux return path and the vacuum chamber. A hollow anode with an adjustable (nominally 1-mm-wide) gap is biased from 10 to 20 kV. Plasma densities of about 10/sup 13/ cm/sup -3/ and temperatures of about 1 keV might be produced by an electron beam and by electron cyclotron resonance heating. Higher-order multipoles (hexapoles and octopoles) also are described.

The geometry and size of the superconducting coils for the Mirror Fusion Test Facility (MFTF) proposed by Lawrence Livermore Laboratory (LLL) impose certain constraints on the Nb-Ti superconductor. The most promising fabrication process is a wrap-around technique in which a superconducting core is ''wrapped'' in stabilizing copper that contains built-in cooling channels. Insulation between pancake coils and turns is provided by perforated sheets and buttons of epoxy-impregnated fiberglass. Preliminary heat-transfer tests conducted on short samples of single conductor and on a nine-conductor bundle are reported and related to the heat generated in ''normal'' conductors. Investigation of joining techniques, necessary because of the length of conductor needed for the MFTF magnet (about 21 km per coil), show that cold-welded butt joints best meet all requirements. In a test coil now being built, approximately 2 km of prototype MFTF conductor will provide a self-field of about 4 T. Supplementary coils will boost the field to about 6.7 T. The test coils will be used to study cryostatic stability, the propagation and recovery of normal zones, and diagnostic techniques.

Two novel techniques which produce a uniform frozen layer of deuterium-tritium on the inside surface of a glass microsphere are presented.

Legal issues affecting ownership of the geopressured resources were examined. It was concluded that consideration of royalty interests indicates that the greatest promise for geothermal resource development would be offered if the geopressured resources were held to be entirely mineral in character. Further, the energy of the geopressured water should be held to be embraced by the standard term other minerals. (MHR)

The LOFT primary system motor generator sets are located in Room B-239 and are connected to the primary coolant pumps by means of a power cable. The calculated average impedance of this cable is 0.005323 ohms per unit resistance and 0.006025 ohms per unit reactance based on 369.6 kVA and 480 volts. The report was written to show the development of power cable parameters that are to be used in the SICLOPS (Simulation of LOFT Reactor Coolant Loop Pumping System) digital computer program as written in LTR 1142-16 and also used in the pump coastdowns for the FSAR Analysis.

Neutral-beam injection is a primary means of building high-energy plasmas in present mirror fusion machines. The injectors need periodic maintenance while a machine is operating, so isolation of them by valving is a desirable chracteristic. Because their energy densities have practical limits, the beams require large cross-sections. Thus, valves having apertures of 10 ft/sup 2/ would be common. Traditional cam-seated vacuum gate valves have been built this large, but they are bulky, costly, and heavy. Improvement is possible by use of an inflatable-bellows assembly for the valve gate. This paper describes the design of such a valve. The design allows a clear aperture of 20 by 36 in. with a valve body that is only 5-/sup 1///sub 4/ in. thick.

The Bevatron/Bevalac is operated, maintained, and continually improved as a national research facility for studies in nuclear science and in biology and medicine. Recent modifications have brought the 21-year-old synchrotron to the threshold of tremendously exciting new studies as the world's most powerful heavy-ion accelerator. In its Bevalac configuration, the machine capitalizes on the coupling of the SuperHILAC to the Bevatron via a 175-meter beam line. The SuperHILAC acts as an injector to provide the Bevatron with high-intensity beams of ions as heavy as argon. At the same time, the SuperHILAC is capable of delivering heavy-ion beams to its own group of experimenters through a computer-linked, time-share system of operation. Research efforts using the Bevalac have included a broad spectrum of nuclear science and cosmic-ray-simulation experiments, as well as intensive studies in biology and medicine aimed principally at diagnostic techniques and preclinical therapy studies for some forms of cancer.

The Andersson-Braun remmeter was modified to improve the directional dependence of the instrument to thermal and fast neutrons and increase its sensitivity to thermal neutrons. The modifications consist of partially rounding the end of the instrument, moving the BF/sub 3/ tube forward by /sup 1///sub 2/ in., increasing the size of the holes in the boron-loaded polyethylene sleeve, replacing one of the boron-loaded end plugs with a polyethylene plug, changing the location of the other end plug, and adding a small disk of cadmium over the hole where the BF/sub 3/ tube enters the moderator. The cost of making these modifications to the Lawrence Livermore Laboratory Andersson-Braun remmeters is approximately $50.00 each. These modifications to the instrument increase the thermal neutron sensitivity by a factor of approximately 3 when exposed at the side and a factor of approximately 9 at the end opposite the instrument packet. The high thermal sensitivity at the instrument packet end (a factor of approximately 17) is eliminated, and the directional dependence to both thermal and fast neutrons is reduced to +-10% (except at the instrument packet end). The sensitivity of the instrument to fast neutrons is increased by approximately 15%. The sensitivity of the modified …

The parametric design study of the tandem mirror reactor (TMR) is described. The results of this study illustrate the variation of reactor characteristics with changes in the independent design parameters, reveal the set of design parameters which minimizes the cost of the reactor, and show the sensitivity of the optimized design to physics and technological uncertainties. The total direct capital cost of an optimized 1000 MWe TMR is estimated to be $1300/kWe. The direct capital cost of a 2000 MWe plant is less than $1000/kWe.

Lathe coolant oil, contaminated with plutonium and having a carbon tetrachloride diluent, is generated in plutonium machining areas at Rocky Flats. A research program was initiated to determine the nature of plutonium in this mixture of oil and carbon tetrachloride. Appropriate methods then could be developed to remove the plutonium and to recycle the oil and carbon tetrachloride. Studies showed that the mixtures of spent oil and carbon tetrachloride contained particulate plutonium and plutonium species that are soluble in water or in oil and carbon tetrachloride. The particulate plutonium was removed by filtration; the nonfilterable plutonium was removed by adsorption on various materials. Laboratory-scale tests indicated the lathe-coolant oil mixture could be separated by distilling the carbon tetrachloride to yield recyclable products.

Two demonstrations of silicon slicing were made for solar cell application. 10 cm ingots of silicon were sliced into 225 wafers (full saw capacity) with over 94 percent yield in both cases. Wafers 0.48 mm thick were sliced with 0.25 mm kerf loss in 19 hours. The slice thickness duplicated currently used wafers. The second demonstration produced 0.30 mm thick slices with 0.25 mm kerf loss in 24 hours. This represents a current best effort with process conditions developed under this contract. Wafer surface damage is shown to be a fine microcrack structure which reduces to a faceted surface topography with 4 ..mu..m of etching. Abrasive particles used in MS sawing do not exhibit particle size degradation or wear of sharp edges. However, built-up silicon debris may effectively blunt cutting edges of the abrasive. Kerf loss was reduced to 0.20 mm in slicing a 10 cm ingot into 0.25 mm slices. This reduces the total silicon requirement per slice by 50 ..mu... Plans include the demonstration of full production capacity with the 0.15 mm thick blades used in this case and a cost analysis of MS sawing for solar cell applications. Limits of wafer thickness (250 ..mu..) and kerf loss …

SOLARSIM is a quantitative computer model which calculates, on a regional and national basis, domestic water and domestic space and water heating loads for single family detached dwellings. SOLARSIM is also capable of performing life-cycle cost analyses of solar space and water heating systems of various levels of intricacy. The main function of SOLARSIM, a solar energy financial incentive model for the applications of solar water heating and solar space and water heating, is to estimate the impacts of different economic and financial incentive scenarios designed to accelerate the market penetration of solar energy heating systems.

A complex, and apparently stochastic, character frequently can be seen to occur in the solutions to simple Hamiltonian problems. Such behavior is of interest, and potentially of importance, to designers of particle accelerators--as well as to workers in other fields of physics and related disciplines. Even a slow development of disorder in the motion of particles in a circular accelerator or storage ring could be troublesome, because a practical design requires the beam particles to remain confined in an orderly manner within a narrow beam tube for literally tens of billions of revolutions. The material presented is primarily the result of computer calculations made to investigate the occurrence of ''stochasticity,'' and is organized in a manner similar to that adopted for presentation at a 1974 accelerator conference.

Fourier line spectra are used to detect noise on the electron beam of an electron beam welder. These spectra are calculated from data in the form of x-ray intensity as a function of time. Statistical tests are described that provide a means of determining the presence of random and periodic signals. The tests remove the uncertainty in deciding if power is present and, if so, at which frequencies. The tests have proven to be consistent and reliable. They are of suitable generality to be useful when it is essential to assess a signal for power quantitatively.

A moisture barrier using water, sodium silicate, formamide, calcium chloride and penechem with a gel time of one-half hour was constructed around a simulated tank 10 feet deep by 10 feet diameter in the subsurface of the 200 West Area. As a test of the moisture barrier integrity, the volume which would normally be occupied by a tank was excavated and filled with water. The barrier was unable to contain the water. The failure to achieve a water-tight barrier was attributed to a leak in the floor grout.
