Radiation-effects limits on copper in superconducting magnets

The determination of the response of copper stabilizers to neutron irradiation in fusion-reactor superconducting magnets requires information in four areas: (1) neutron flux and spectrum determination, (2) resistivity changes at zero field, (3) resistivity changes at field, and (4) the cyclic irradiation and annealing. Applications of our current understanding of the limits of copper stabilizers in fusion-reactor designs are explored in two examples. Recommendations for future additions to the data base are discussed.

Pulse power for the RAPIER B Amplifier KrF laser system

The RAPIER B Amplifier electron beam system has been completed and produces 36kJ of 450 keV electrons in a 150 ns pulse to be used for pumping a KrF laser amplifier. The operating characteristics of the system have been studied. The efficiency of conversion of energy stored in the Marx generator to electron beam output is 72 +- 3% including an 89% designed transfer efficiency. The system is triggered electrically with a 150 ns delay from the command trigger to machine output. The rms jitter for the six individual modules range from 1.6 to 3.9 ns and the average timing difference between the earliest and latest module output is 12 ns. Film dosimetry indicates no observable interaction between the magnetically isolated beams in the module diodes and fluorescence measurements do not indicate strong interaction in the gas filled laser cell. Current probe measurements show no significant change in beam size during the output pulse. Energy deposition profiles agree reasonably with Monte Carlo calculations up to pressures of 1.5 atm.

Squid based beam current meter

A SQUID based beam current meter has the capability of measuring the current of a beam with as little as 30 x 155 antiprotons (with a signal to noise ratio of 2). If low noise dc current is used to cancel most of the beam or an up-down counter is used to count auto-resets this sensitivity will be available at any time in the acumulation process. This current meter will therefore be a unique diagnostic tool for optimizing the performance of several Tev I components. Besides requiring liquid helium it seems that its only drawback is not to follow with the above sensitivity a sudden beam change larger than 16 ..mu..A, something that could be done using a second one in a less sensitive configuration.

System for intelligent teleoperation research

The Automation Technology Branch of NASA Langley Research Center is developing a research capability in the field of artificial intelligence, particularly as applicable in teleoperator/robotics development for remote space operations. As a testbed for experimentation in these areas, a system concept has been developed and is being implemented. This system, termed DAISIE (Distributed Artificially Intelligent System for Interacting with the Environment), interfaces the key processes of perception, reasoning, and manipulation by linking hardware sensors and manipulators to a modular artificial intelligence (AI) software system in a hierarchical control structure. Verification experiments have been performed: one experiment used a blocksworld database and planner embedded in the DAISIE system to intelligently manipulate a simple physical environment; the other experiment implemented a joint-space collision avoidance algorithm. Continued system development is planned.

Magnetic-field design of the accumulator multipole magnet

A multiple magnet using the FFAG graded coil technique has been designed with the aid of the two dimensional magnet modelling code Poisson. Rapid design interaction in problem formulation has been achieved with a new finite element mesh generator in which mesh densities can be manipulated to overcome difficulties in mesh topologies when spanning the grid over the problem domain.

(Design and operation of a portable ethanol plant). Final report. [Small-scale (5-10 gal/h)]

A portable distillation plant with a packed reflux column was designed and built that is capable of producing 10 to 15 gallons of 190 proof ethanol per hour. Several kinds of feedstocks were used to produce ethanol. Corn served as a good feedstock and was easily processed in the still. However, because of the present high prices of corn and the manual labor for operation it cannot be used to produce ethanol commercially as a fuel at prices competitive with petroleum fuels. Cellulosic feedstocks such as paper, sawdust and grasses and leaves were enzymatically degraded to sugars and fermented to ethanol. Because of the manual labor required and small capacity of the still total operation costs would preclude competitive fuel prices. However, such a plant could be used on a farm for production of a supplementary fuel or for independence from petroleum fuels. The trials with cellulosic materials did give evidence that such feedstocks are plausible sources for ethanol when produced on a large scale in an automated production plant. On a large scale basis ethanol could be produced competitively as an alternative fuel for gasoline.

Scaling of laser-plasma interactions with laser wavelength and plasma size

Plasma size is an important parameter in wavelength-scaling experiments because it determines both the threshold and potential gain for a variety of laser-plasma instabilities. Most experiments to date have of necessity produced relatively small plasmas, due to laser energy and pulse-length limitations. We have discussed in detail three recent Livermore experiments which had large enough plasmas that some instability thresholds were exceeded or approached. Our evidence for Raman scatter, filamentation, and the two-plasmon decay instability needs to be confirmed in experiments which measure several instability signatures simultaneously, and which produce more quantitative information about the local density and temperature profiles than we have today.

Reevaluation of an individual's radiation exposure at NTS in 1963-64. [FRAN reactor]

The FRAN prompt burst reactor began operation at NTS on November 1, 1962 and continued in use until April 1965. From January 2, 1963 to August 12, 1964, an individual periodically performed maintenance and troubleshooting functions on various components of the FRAN reactor system. In June, 1980, the individual requested a review of the radiation dose that he received from his involvement with the FRAN reactor. An evaluation of the individual's radiation dose associated with the FRAN reactor operation was performed. This report details the reevaluation of the individual's estimated radiation dose from the FRAN reactor assembly, as derived from computer calculations, GODIVA-IV measurements, personnel dosimetry results, and a reconstruction of work scenarios.
