Recommendations of a committee for a new standard to meet needs of new high-energy physics experiments are summarized in a nontechnical manner. Existing standards, including CAMAC, were examined; it was felt that none would meet the future needs of high-energy physics. The original committee gave its recommendations and disbanded. The design committee has begun its work; it anticipates finishing in about two years, in time for application of its recommendations to ISABELLE. (RWR)

The power, voltage, energy and other requirements of electron and ion beam fusion targets are reviewed. Single shell, multiple shell and magnetically insulated target designs are discussed. Questions of stability are also considered. In particular, it is shown that ion beam targets are stabilized by an energy spread in the ion beam.

Light-water power reactors use Zircaloy tubing as cladding to contain the UO/sub 2/ fuel pellets. In-service operating conditions impose an external hydrostatic force on the cladding, causing it to creep down into eventual contact with the fuel. Knowledge of the rate of such creepdown is of great importance to modelers of fuel element performance. An experimental system was devised for studying creepdown that meets several severe requirements by providing (1) correct stress state, (2) multiple positions for measuring radial displacement of the cladding surface, (3) high-precision data, and (4) an experimental configuration compact enough to fit in-reactor. A microcomputer-controlled, eddy-current monitoring system was developed for this study and has proven highly successful in measuring cladding deformation with time at temperatures of 371/sup 0/C (700/sup 0/F) and higher, and at pressures as high as 21 MPa (3000 psig).

Preliminary calculations are given that indicate that a coaxial plasma gun might scale reasonably to reactor-grade operating conditions. Ongoing experiments and numerical simulations should shed some light on the validity of the described scaling laws.

This paper describes the present design and future capability of the high-voltage test stand for neutral-beam sources at Lawrence Livermore Laboratory. The stand's immediate use will be for testing the full-scale sources (120 kV, 65 A) for the Tokamak Fusion Test Reactor. It will then be used to test parts of the sustaining source system (80 kV, 85 A) being designed for the Magnetic Fusion Test Facility. Following that will be an intensive effort to develop beams of up to 200 kV at 20 A by accelerating negative ions. The design of the test stand features a 5-MVA power supply feeding a vacuum tetrode that is used as a switch and regulator. The 500-kW arc supply and the 100-kW filament supply for the neutral-beam source are battery powered, thus eliminating one or two costly isolation transformers.

The two DOE-owned facilities at Hanford, the Fuels and Materials Examination Facility (FMEF), and the Fusion Materials Irradiation Test Facility (FMIT), are described. The performance measurement systems used at these two facilities are next described. (DLC)

This paper is a sequel to the one prepared by Atkinson, et al., in which the authors described the vacuum system of Lawrence Livermore Laboratory's Tandem Mirror Experiment (TMX). We discuss here the final configuration, liquid nitrogen (LN/sub 2/) supply, and operation of the complete TMX vacuum system. The assembled vacuum system consists of two plug tanks with a volume of approximately 60 m/sup 3/ each and a center cell tank with a volume of approximately 10 m/sup 3/. In each plug tank there are 145 m/sup 2/ of titanium-gettered, LN/sub 2/-filled panels, which allow a pumping speed calculated to be 5 x 10/sup 7/ l/s for a period of 50 ms. The system maintains an operating pressure in the plasma chamber on the order of 10/sup -6/ Torr while 24 neutral-beam injectors are introducing 700 Torr l/s of hydrogen into the vacuum chamber.

In work for the United States Nuclear Regulatory Commission, Lawrence Livermore Laboratory is developing an assessment procedure to evaluate the effectiveness of a potential nuclear facility licensee's material control (MC) system. The purpose of an MC system is to prevent the theft of special nuclear material such as plutonium and highly enriched uranium. The key in the assessment procedure is the generation and analysis of the adversary event sets by a directed graph and fault-tree methodology.

For the United States Nuclear Regulatory Commission, a procedure was developed and tested for the evaluation of Material Control and Accounting (MC and A) Systems at nuclear fuel facilities. This procedure, called the Structured Assessment Approach, SAA, subjects the MC and A system at a facility to a series of increasingly sophisticated adversaries and strategies. A fully integrated version of the computer codes which assist the analyst in this assessment will become available in October 1979. The concepts of the SAA and the results of the assessment of a hypothetical but typical facility are presented.

An overall view is given of progress and plans for pressing forward with mirror research at Livermore. No detail is given on any one subject, and many interesting investigations being carried out at University laboratories in the U.S. that augment and support efforts at Livermore are omitted.

In any complex system, the interesting problems occur at the interface of dissimilar subsystems. Control of the Mirror Fusion Test Facility (MFTF) begins with the US Congress, which controls the dollars, which control the people, who control the nine top-level minicomputers, which control the 65 microprocessors, which control the hardware that controls the physics experiment. There are many interesting boundaries across which control must pass, and the one that this paper addresses is the man-machine one. For the MFTF, the man-machine interface consists of a system of seven control consoles, each allowing one operator to communicate with one minicomputer. These consoles are arranged in a hierarchical manner, and both hardware and software were designed in a top-down fashion. This paper describes the requirements and the design of the console system as a whole, as well as the design and operation of the hardware and software of each console, and examines the possible form of a future man-machine interface.

An overview of inertial confinement fusion pellet physics is given. A discussion is presented of current estimated ICF driver requirements and a couple of pellet examples. The physics of driver/plasma coupling for two drivers which are being considered, namely a laser driver and a heavy ion accelerator driver, is described. Progress towards inertial confinement fusion that has been made using laser drivers in target experiments to date is discussed.

The STORET/MSP option was used to obtain county aggregated information on ambient water quality for sixty parameters during the period 1950 to 1978. Masks, extended EXTRACT specifications and bounds on allowable values limited inclusion of erroneous data. Remark codes were required to aggregate STORET parameters to obtain increased numbers of observations. Numerous statistical analyses led to the conclusions that medians were more useful than means, that trimming on number of observations was required to eliminate counties with extreme values, and that many parameters required logarithmic transformation to be useful in regional analyses. County aggregated data for nineteen water quality parameters were examined in terms of their ability to describe qualitative chemical characteristics of water. Anion--cation balances as well as expected relationships between conductivity and other parameters were correctly accounted for. Factor analysis indicated the existence of three principal components describing patterns between metal ions, non-metal ions, and alkalinity-bicarbonate, respectively. These factors were used in place of the original complete set of water quality parameters in a structural equation approach describing relationships between variables of mans activites. It was found that counties with high industrial electric consumption, farming and mineral shipments tended to have increased levels of most water quality parameters. …

A selective multiphoton photochemical process has been used to enrich nitrogen-14 isotope in methylamine. A separation factor of two has been achieved for irradiation of CH/sub 3/N/sup 14/H/sub 2//CH/sub 3/N/sup 15/H/sub 2//NO sample with the P(24) line of the 9.6 ..mu.. CO/sub 2/ laser transition. The threshold laser energy fluence for reaction is roughly 30 joules/cm/sup 2/. The vibrational isotope shift of methylamine at 9.6 ..mu.. region was found to be 12.5 cm/sup -1/. The selectivity of the photochemical reaction appears to be limited by the overlap of vibrational-rotational lines of CH/sub 3/N/sup 14/H/sub 2/ and CH/sub 3/N/sup 15/H/sub 2/ molecules due to power broadening under the intense laser field.

The National Resource for Computation in Chemistry was established to make information on existing and developing computational methodologies available to all segments of the chemistry community, to make state-of-the-art computation facilities accessible to the chemistry community, and to foster research and development of new computational methods for application to chemical problems. Attention was directed to algebraic methods because of their continuing importance in chemical applications. This volume contains digests of the contributions to the workshop of August 9--11, 1978. Presentations were given on eigenvalue problems, linear systems of equations, and integral transformations. One of the papers in this volume was abstracted and indexed separately. (RWR)

The Antares laser will require that about 100 high-precision NaCl windows of 18-in. diameter be produced, maintained, and repaired. To aid the industry in achieving the required production rates, a polishing development program was undertaken by LASL's Laser Division in collaboration with the Air Force and International Laser Systems. The design and initial shakedown of the polishing machine is described. Preliminary results indicate the machine's design is sound, its operation is generally simple, and it should be capable of finishing 18-in. NaCl to better than lambda/2 visible and 20-10 surface. Shakedown work with glass has demonstrated 0-0 surface, complete absence of edge roll, and lambda/16 over 12 in., and lambda/6 over 19 in.

Many human vigilance experiments are summarized and principles are extracted which should be useful in designing and evaluating a nuclear material safeguard system. A human is a poor observer and is not a dependable part of any man-machine system when required to function as an observer. There are a few techniques which improve his performance by providing feedback. A conceptual model is presented which is helpful in design and evaluation of systems. There is some slight experimental support for the model. Finally, some techniques of time study and statistical control charting will be useful as a means of detecting nuclear diversion attempts.

An assessment of the effectiveness of the Material Control and Accounting System (MC and A) in a hypothetical nuclear facility, the TEST BED is presented. The key in assessing the TEST BED is the generation of adversary event sets. The adversary event sets are generated and analyzed by a directed graph (digraph) and fault tree procedure. Although the TEST BED is a system hardened against SNM theft, the assessment of the TEST BED finds several major weaknesses, and also indicates possible modifications to correct these weaknesses.

A system model of the mirror hybrid reactor has been developed. The major components of the model include (1) the reactor description, (2) a capital cost analysis, (3) various fuel management schemes, and (4) an economic analysis that includes the hybrid plus its associated fission burner reactors. The results presented describe the optimization of the mirror hybrid reactor, the objective being to minimize the cost of electricity from the hybrid fission-burner reactor complex. We have examined hybrid reactors with two types of blankets, one containing natural uranium, the other thorium. The major difference between the two optimized reactors is that the uranium hybrid is a significant net electrical power producer, whereas the thorium hybrid just about breaks even on electrical power. Our projected costs for fissile fuel production are approximately 50 $/g for /sup 239/Pu and approximately 125 $/g for /sup 233/U.

The laser and fluorescence output of KrCl and ArF were measured and the effect of the gas mixture on the laser output was determined. Possible mechanisms for the effects observed are suggested. (JSR)

Polarized x-radiation is shown to be a superior and practical excitation source for measuring trace elements by energy dispersive x-ray fluorescence. In this study, polarization was obtained by scattering the primary beam at 90/sup 0/ from boron carbide. The losses inherent in the geometric requirements and the polarizer efficiency can be more than compensated for by using a close-coupled system and a standard, high-power x-ray tube. With the system described here, which uses a molybdenum anode x-ray tube, detection limits for the elements from K to Sr in NBS Standard Orchard Leaves are approximately 2 to 4.5 times lower using polarized excitation as compared to direct excitation, and about 1 to 3 times lower as compared to secondary excitation.

Polyethylene foils and parylene disks 5 to 10 ..mu..m thick have been irradiated by CO/sub 2/ laser pulses focused to flux levels in the 10/sup 13/ to 10/sup 14/ W/cm/sup 2/ range. A CO/sub 2/ laser system, ''Valkyrie,'' fabricated from commercially available components was assembled for these experiments. The switched-out nanosecond pulse is next amplified by two cold-cathode electron-beam sustained amplifiers built by Systems, Science, and Software, Inc. After passing through the beam diagnostics tables, the beam is finally focused on the target in the chamber in the foreground. Some results using this system are described. (MOW)

One studies the dynamical system described by the Hamiltonian H = H/sub 0/ + EPSILON V, where H/sub 0/ = /sup 1///sub 2/ p/sup 2/ - cos x, V = - cos (lambda x - ..cap omega..t). One encounters this system in a number of problems of practical importance. In addition, the system has intrinsic interest for the theory of adiabaticity and stochasticity. The invariant action J of the unperturbed Hamiltonian H/sub 0/ is subject to strong modification or destruction because of the perturbation EPSILON V. Absence of an invariant (i.e., stochasticity) occurs in a phase space region whose size and shape vary with the three parameters EPSILON, lambda, ..cap omega... Previous studies have varied the amplitude of a perturbation (our epsilon); one emphasizes the strong dependences on the space (lambda) and time (..cap omega..) scales of the perturbation. Results show that a perturbation is most effective at causing stochastic motion if its space and time scales are comparable (lambda - 1, ..cap omega.. - 1) to those in the unperturbed Hamiltonian H/sub 0/.

Paramagnetic ions in glass reside in a distribution of physically different environments. By using a tunable laser source, selected groups of ions within an inhomogeneously broadened absorption band are excited and line-narrowed fluorescence is observed. The technique of laser-induced fluorescence line narrowing has been applied to several rare-earth ions in glasses to investigate site-to-site variations in energy levels, probabilities for radiative and non-radiative transitions, homogeneous line broadening, and energy transfer between ions. Results and interpretations of these experiments are reviewed, and possible extensions of these techniques are discussed. 25 references, 3 fig.
