Cool pool development. Quarterly technical report No. 2, June-December 1979
The Cool Pool is a variation of the evaporating roof pond idea. The pool is isolated from the living space and the cooled pond water thermosiphons into the water columns located within the building. A computer model of the Cool Pool and the various heat and mass transfer mechanisms involved in the system are discussed. Theory will be compared to experimental data collected from a Cool Pool test building.

Effects of pulsed dual-ion irradiation on phase transformations and microstructure in Ti-modified austenitic alloy
The influence of pulsed 4 MeV Ni ion bombardment, with and without simultaneous helium injection, has been explored in a low swelling, Ti-modified austenitic stainless steel. Irradiations were carried out to 70 dpa at 950/sup 0/K; the pulsing frequencies were either 60 s on/off or 1 s on/off. Compared to continuous irradiation, pulsing caused a decrease in the interstitial loop diameter at 1 dpa, although at higher doses the overall dislocation density was not affected. Pulsing and helium both promoted the stability of MC precipitates and retarded the subsequent G phase formation; in some cases G-phase was suppressed and eta phase formed instead. Small bubble-like cavities were observed to grow into large voids after steady dual beam irradiation to 70 dpa. However, this conversion was suppressed by pulse irradiation to 70 dpa and furthermore the sizes of the small cavities were somewhat reduced. The results are explained in terms of current mechanistic understanding of mean point defect kinetics and the evolution of microstructure and microcomposition during irradiation with superimposed annealing periods.

From page 2: The National Institute of Standards and Technology research reactor is a national center for the application of reactor radiation to a variety of problems of national concern. Major program areas at the reactor include the application of neutron scattering methods to research in materials science, trace analysis by neutron activation, nondestructive evaluation (via neutron radiography and scattering), neutron standards and dosimetry , and isotope production and radiation effects.

Silicon-on-ceramic process: silicon sheet growth and device development for the large-area silicon sheet task of the Low-Cost Solar Array Project. Annual report No. 5, September 29, 1979-September 30, 1980
The objective of this research is to investigate the technical feasibility of producing solar-cell-quality sheet silicon to meet the DOE 1986 cost goal of 70 cents/watt. The silicon-on-ceramic approach is to coat a low-cost ceramic substrate with large-grain polycrystalline silicon by unidirectional solidification of molten silicon. Results are reported. A new silicon-coating system, SCIM-II, was designed and constructed. A design strategy to avoid buckling and breaking of substrates has been formulated, implemented, and verified. Detailed thermal modeling of the heating and cooling zones has been performed, and the results have been compared with experiment. A number of modifications have been made in SCIM-II to implement the strategy to minimize thermal stress and to improve reproducibility of coating conditions. Dip-coating has been continued in order to supply material for cell fabrication, since impure carbon parts have been used in the SCIM-coater while changes were still being made. The best cell had a total-area efficiency of 10.5% (AM1, AR) for a cell area of 5 cm/sup 2/. The highest efficiencies were produced with a PH/sub 3/ diffusion at 850/sup 0/C, followed by a slow cooldown at about 5/sup 0/C/min. Theoretical modeling of SOC solar cells shows that present cell performance is limited …

Aerated atomization of coal water slurry
In order to better understand the process of slurry atomization, it is important to observe the influence of fluid non-Newtonian rheological behavior on the spray formation process. As a first step, glycerin-water solutions have been atomized. This report describes findings of photographs taken during atomization. 19 figs.

Studies of autoionizing states relevant to dielectronic recombination. Progress report for the third year
An important loss process in CTR plasmas is the process of dielectronic recombination, which proceeds via autoionizing states. At this date, however, this problem is not fully understood, largely because of the nearly complete lack of fundamental atomic data on high excited autoionizing states. In this document, we outline the continuation of a program to investigate the properties of autoionizing states of alkaline earth metals by means of a novel laser excitation technique developed at SRI. This approach will allow us to study, for the first time, autoionizing states of arbitrary n, and l in a controlled environment. Specifically, we plan to measure autoionization rates and branching ratios as a function of n and l and the effects of electric fields. These experiments should yield the basic atomic data, autoionization rates, required as inputs to sophisticated model calculations of dielectronic recombination rates.

Optical-emission studies in the ion-focused regime
The utility of optical emissions for diagnostic purposes in the ion-focused regime is explored. Two possible uses of the emissions are examined: (1) the time delay of 337.1-nm emissions relative to 391.4-nm emissions is observed to scale with the beam-neutralization time, and (2) emissions at 391.4 nm may determine beam-current density at the front of the beam.

Magnets for the Mirror Fusion Test Facility: testing of the first Yin-Yang and the design and development of other magnets
Completed in May 1981, the first Yin-Yang magnet for the tandem Mirror Fusion Test Facility (MFTF-B) at Lawrence Livermore National Laboratory (LLNL) was successfully tested in February 1982 to its full design field (7.68 T) and current (5775 A). Since that time, the entire magnet array has been reconfigured - from the original A-cell to an axicell design. The MFTF-B magnet array now contains a total of 26 large superconducting coils: 2 sets of yin-yang pairs, 2 sets of transition magnets (each containing two coils), 2 sets of axicell magnets (each containing three coils), and 12 central-cell solenoids. This paper chronicles recent magnet history - from te testing of the initial yin-yang set, through the design of the axicell configuration, to the planned development of the system.
