We have observed 1 event consistent with the signature expected of the rare decay of a positive kaon to a positive pion and a neutrino anti-neutrino pair. In the examined momentum region of 211 to 230 MeV/c in the center of mass of the kaon we estimated the backgrounds to be about 0.08 {+-} 0.03 events. From this observation we estimate the branching ratio to be 4.2{sub {minus}3.5}{sup +9.7} x 10{sup {minus}10}. In this presentation I will explain the experiment, and the analysis techniques. I will also discuss the expected improvements in the near future from the analysis of new data sets.

Two recent court decisions have called into question the viability of environmental citizen suits. In Steel Co., the Supreme Court denied plaintiff standing in a citizen suit where the defendant came into compliance after plaintiff sent its notice of intent to sue, but before it filed the complaint. Subsequently, the Fourth Circuit in Laidlaw invoked mootness doctrine to extend Steel Co.

The objectives of the pilot study were to investigate the limitations of the technique for imaging the presence, extent, and boundaries of the low-resistance intervals and associated carbonate sediments.

From August 12--27, 1998 X-ray K-edge measurements were made on drain lines in seven rooms in Wilhelm Hall, Ames Laboratory. The purpose of these measurements was to determine the extent of thorium (and other heavy metal) contamination inside these pipes. The K-edge method is a noninvasive inspection technique that can provide accurate quantification of heavy metal contamination interior to an object. Of the seven drain lines inspected, one was found to have no significant contamination, three showed significant thorium deposits, two showed mercury contamination, and one line was found to contain mercury, thorium and uranium. The K-edge measurements were found to be consistent with readings from hand-held survey meters, and provided much greater detail on the location and amount of heavy metal contamination.

This project is currently evaluating non-thermal plasma (NTP) technologies for treating jet-engine exhaust arising from DoD test facilities. In the past, some economic analyses for NTP de-NO{sub x} have shown that it is not economical, compared to other techniques. The main reasons for this conclusion was that the previous analyses examined stand-alone, or less mature electrical-discharge reactors, or electron-beam based systems that incorporated both chemical additives and quite expensive electron accelerators. Also, in contrast to more recent developments, both the discharge and electron-beam techniques of the past did not extensively incorporate methods to increase the yields of active NO{sub x}-decomposing species. In an earlier White paper and a Project Report, the authors have analyzed the costs of more mature NTP systems incorporating chemical additives and new-concept NTP technologies for jet-engine emissions control and have shown lower exhaust-gas treatment costs for NTP systems compared to baseline standard de-NO{sub x} technologies like Selective Catalytic Reduction (SCR) combined with a wet scrubber or SCR combined with an electrostatic precipitator (ESP). In this paper, the authors will examine their most-promising candidate NTP reactor systems for a field-pilot demonstration on jet-engine exhaust and discuss the economic analyses for these hybrid units, which show that the …

The spheromak attributes� - internally generated toroidal magnetic field without linked coils, dynamo-driven plasma current resulting from helicity injection, and compactness - lead to attractive reactor options ranging from �conventional� steady-state designs, to high beta pulsed configurations, and to-the core of a Magnetized Target Fusion (MTF) device. The resolution of the physics issues associated with these attributes, discussed in later sections, will determine the size and viability of the reactors. Preliminary designs, however, have been made and illustrate the opportunities.

This report describes the results of the Savannah River Technology Center (SRTC) program to address bubble gas release potential as requested by Concentration, Storage and Transfer Engineering. Researchers from the Waste Processing Technology Section (WPTS) and Immobilization Technology Section (ITS) contributed to the results presented.

Sputter-deposited W-based contacts on p-GaN (N{sub A} {approximately} 10{sup 18} cm{sup {minus}3}) display non-ohmic behavior independent of annealing temperature when measured at 25 C. The transition to ohmic behavior occurs above {approximately} 250 C as more of the acceptors become ionized. The optimum annealing temperature is {approximately} 700 C under these conditions. These contacts are much more thermally stable than the conventional Ni/Au metallization, which shows a severely degraded morphology even at 700 C. W-based contacts may be ohmic as-deposited on very heavily doped n-GaN, and the specific contact resistance improves with annealing up to {approximately} 900 C.

As a follow-up to a bench-top experiment (1), the Savannah River Technology Center (SRTC) at the Savannah River Site (SRS) carried out a full-scale test of a "large-diameter" bubbler (LDB) to measure liquid-level and density in high yield stress slurries. The test was the final step in a process to find an instrument that could effectively and economically operate in the existing mixing tank environments. Positive results would lead to implementation of the LDB. This new bubbler replaced two inadequate instruments: an expensive technology, a Holledge probe, which needed replacing twice a year and "standard bubblers," which plugged in as little as four hours of operation. Three LDBs, at different depths, were tested under highly prototypic conditions from November 27, 1996, to January 23, 1997, using the full-scale test facilities at SRS. The instruments were subjected to 58 days of slurry operation; 14 days of which the slurry was brought to boiling temperatures. The results showed that the LDBs (6.7 cm inside diameter) operated successfully by not plugging with the glass-frit ladened slurry, which was maintained at a minimum temperature of 50 degrees C and at approximatley 102 degrees C during days of boiling. A recommendation was made to implement …

The paper reviews recent experimental results on the formation of through-thickness texture gradients during non-uniform rolling and, in particular, addresses their materials-dependence. For that purpose, two different materials (Cu and a low carbon steel) were subjected to non-uniform deformation by cold rolling without application of a lubricant. The effects of the different local strain states through the sheet thickness on microstructure and crystallographic texture were studied by X-ray texture analysis and microstructure observations and compared to results obtained in uniformly deformed sheets.

The research of the EBIT (Electron Beam Ion Trap) program in N Division of the Physics and Space Technology Directorate at LLNL continues to contribute significantly to the understanding of physical processes with low energy highly charged ions in atomic physics, plasma physics, and material science. Low-energy highly charged ions (up to U⁹²⁺), provided by the EBIT facilities, provide a unique laboratory opportunity to study high field effects in atomic structures and dynamic interaction processes. The formation, existence, and structure of highly charged ions in astrophysical environments and laboratory plasmas make highly charged ions desirable for diagnosing various plasma conditions. The strong interaction of highly charged ions with matter and the response of solid surfaces make them a sensitive analysis tool and possibly a future capability for materials modifications at the atomic scale (nano technology). These physical applications require a good understanding and careful study of the dynamics of the interactions of the ions with complex systems. The EBIT group hosted an international conference and a workshop on trapped charged particles. The various talks and discussions showed that physics research with trapped charged particles is a very active and attractive area of innovative research, and provides a basis for research …

The Falling Droplet device was used to measure the extensional viscosity of a variety of aqueous polymer solutions. These solutions were atomized with the miniature ''inverse'' twin-fluid atomizer. Droplet size measurements were made with a Malvern laser diffraction particle sizing device. Droplet sizes measured did not rank strictly according to either low-shear rate shear viscosity or extensional viscosity.
