First CSDP (Continental Scientific Drilling Program)/thermal regimes core hole project at Valles Caldera, New Mexico (VC-1): Drilling report
This report is a review and summary of the core drilling operations of the first Valles Caldera research borehole (VC-1) under the Thermal Regimes element of the Continental Scientific Drilling Program (CSDP). The project is a portion of a broader program that seeks to answer fundamental scientific questions about magma, rock/water interactions, and volcanology through shallow (<1-km) core holes at Long Valley, California; Salton Sea, California; and the Valles Caldera, New Mexico. The report emphasizes coring operations with reference to the stratigraphy of the core hole, core quality description, core rig specifications, and performance. It is intended to guide future research on the core and in the borehole, as well as have applications to other areas and scientific problems in the Valles Caldera. The primary objectives of this Valles Caldera coring effort were (1) to study the hydrogeochemistry of a subsurface geothermal outflow zone of the caldera near the source of convective upflow, (2) to obtain structural and stratigraphic information from intracaldera rock formations in the southern ring-fracture zone, and (3) to obtain continuous core samples through the youngest volcanic unit in Valles Caldera, the Banco Bonito rhyolite (approximately 0.1 Ma). All objectives were met. The high percentage of core …

Dipole strength functions in the actinide mass region
We have calculated a number of neutron- and photon-induced reactions for the actinide nuclei /sup 232/Th, /sup 238/U, and /sup 237/Np. By fitting average resonance capture (ARC) measurements and total neutron capture data, we deduced absolute dipole strength functions for /sup 233/Th and /sup 239/U. We have found that the M1/E1 ratio is the same as in the /sup 176/Lu case, but the total transition strength was larger by about 27%. 17 refs., 4 figs., 1 tab.

Conversion-electron experiment to characterize the decay of the /sup 237/Np shape isomer
Conversion electrons from the decay of low-lying levels of /sup 237/Np have been measured to detect the population of these levels by gamma-ray decay of the /sup 237/Np shape isomer. Analysis of the 208-keV transition L conversion-electron peak gives an upper limit of about 17 ..mu..b for the population of the 3/2/sup -/ 267-keV level in /sup 237/Np from the shape isomer decay. Model calculations are compared with the measured limit. Improvements are suggested for this experiment. 9 refs., 4 figs.

An Examination of Two Significant Percussion Compositions: Karlheinz Stockhausen's Zyklus and Ingolf Dahl's Duettino Concertante, a Lecture Recital Together with Five Recitals of Selected Works of A. Ginastera, A. Wilder, W. Kraft, and Others
Zvklus (1959) by Karlheinz Stockhausen and Duettino Concertante (1966) by Ingolf Dahl represent two of the most significant percussion compositions that present the percussionist as soloist. The performer of these works, either unaccompanied or accompanied by a non-percussion instrument, is featured as executant, interpreter, and improvisor. They are regarded as classics in the medium of multiple percussion because of their frequency of performance and their profound effect on notation, musical composition, and the technical expectations of the percussionist. This paper examines these compositions and their historical significance to both percussion literature and the percussionist. Each of these compositions is analzyed by examining instrumentation, compositional procedures, and performance problems. Finally, the notational procedures and role of the performer in these compositions are compared. A discussion of the development of the percussion batterie, percussion ensemble, and the important early solo multiple percussion compositions provides historical perspective for these compositions. This perspective is enhanced by consideration of biography, influences, and stylistic development of each composer.

Core lithology, Valles caldera No. 1, New Mexico
Vallas caldera No. 1 (VC-1) is the first Continental Scientific Drilling Program research core hole in the Vallas caldera and the first continuously cored hole in the region. The hole penetrated 298 m of moat volcanics and caldera-fill ignimbrites, 35 m of volcaniclastic breccia, and 523 m of Paleozoic carbonates, sandstones, and shales with over 95% core recovery. The primary research objectives included coring through the youngest rhyolite flow within the caldera; obtaining structural and stratigraphic information near the intersection of the ring-fracture zone and the pre-caldera Jemez fault zone; and penetrating a high-temperature hydrothermal outflow plume near its source. This report presents a compilation of lithologic and geophysical logs and photographs of core that were collected while drilling VC-1. It is intended to be a reference tool for researchers interested in caldera processes and associated geologic phenomena.

The Songs of Lennox Berkeley: A Lecture Recital, Together with Three Recitals of Selected Works of F.P. Schubert, G. Fauré, C. Debussy, F. Poulenc, M. Ravel, H. Wolf, J.S. Bach, G.F. Handel, I. Stravinsky, and Others
The English art song in the 20th-century presents a performance challenge unique in the solo song repertoire. Unlike the corresponding bodies of German Lied and French mélodie, which proceeded from a well-ingrained national tradition of music and poetry, the English art song had no such background. The many British composers who have contributed to the song literature of this century reflect varied backgrounds and influences. Lennox Berkeley combined his English heritage with the French background of his mother's family, largely self-taught musical skills and an innate sensitivity to poetry to become one of the most prominent song composers of this century. He trained with Nadia Boulanger, gaining exposure to the formal and melodic techniques of Faure and the neo-classicism of Stravinsky. Berkeley composed a total of seventy-eight solo songs. His acceptance and furtherance of a fundamentally traditional songmaker's craft place him more directly in the post-war line of succession of English song than Benjamin Britten, whose innovative musical techniques place him in the vanguard of new music.This document explores those aspects of Berkeley's life and work that contribute to his compositional choices. It provides an overview of all of Berkeley's known solo songs as well as a more detailed analysis …

Field evaluation of a tensiometer data acquisition system for hydrologic studies of waste disposal site design. [Shallow land burial]
Commercially available differential pressure transducers, tensiometers and a data acquisition system were combined to study soil water tension changes with time within two trench cap designs used for the shallow land burial of waste materials. Apparent diurnal variations in soil water tension measured with this system are evaluated relative to field variations in temperature, atmospheric pressure and soil water content. Ongoing research is described which should improve the reliability of future soil water tension data collected in the field. 10 refs., 5 figs.

Operational Experience With Light Ions at BNL
A new transfer line has joined the Tandem Van de Graaff facility and the AGS at Brookhaven National Laboratory, permitting the acceleration of light ions (up to sulfur) to 14.5 GeV/nucleon. The Tandem, operating with a pulsed ion source, supplies a fully stripped ion beam at about 7 MeV/nucleon to the AGS. A new low frequency rf system accelerates the beam in the AGS to about 200 MeV/nucleon. The previously existing rf system completes the cycle. High energy ion beams are delivered using standard resonant extraction to four experimental beam lines. Details of techniques and preliminary performance and operational characteristics are discussed.

Effect of rapid solidification on stainless steel weld metal microstructures and its implications on the Schaeffler diagram
An investigation was carried out to determine the effect of rapid solidification on the weld metal microstructure of austenitic stainless steels and its implication on the ferrite constitution diagram. A wide variety of stainless steels were laser welded at different welding speeds and laser power levels. Results indicate that both weld pool cooling rate and the postsolidification solid state cooling rates have a profound effect on the microstructures. For the steels investigated, the microstructures ranged from duplex austenite (..gamma..) + ferrite (delta) to fully austenitic or fully ferritic. These microstructures were found to be sensitive to both cooling rates and composition. The observed results are rationalized based on rapid solidification theory. This investigation indicates that solidification rates and postsolidification cooling rates have a profound effect on the observed microstructures, thus making it impossible to predict the microstructures of rapidly cooled weld metal from the conventional constitution diagrams. The influence of the observations made in this investigation on the Schaeffler diagram is demonstrated, and possible corrections to the constitution diagram incorporating the cooling rate effects are proposed. 23 refs., 17 figs., 4 tabs.

Design considerations for a negative ion source for dc operation of high-power, multi-megaelectron-volt neutral beams
A dc negative hydrogen and/or deuterium ion source is needed to produce high-power, high-energy neutral beams for alpha diagnostics and current drive applications in fusion devices. The favorable beam particle energy for such applications extends to 1.5 MeV/amu. Continuous-wave (cw) radiofrequency quadrupole (RFQ) accelerators have been proposed to accelerate negative ions efficiently to this energy range. In this paper, the desired beam properties for ion beams injected into cw RFQ accelerators are summarized. A number of candidate ion sources being developed at Culham, JAERI, LBL, and ORNL may prove useful for these applications. The properties of the Volume Ionization with Transverse Extraction (VITEX) ion sources being developed at ORNL are presented. Scaling such a dc ion source to produce ampere beams is discussed. 53 refs., 4 figs., 2 tabs.

Thermodynamic data bases for multivalent elements: An example for ruthenium
A careful consideration and understanding of fundamental chemistry, thermodynamics, and kinetics is absolutely essential when modeling predominance regions and solubility behavior of elements that exhibit a wide range of valence states. Examples of this are given using the ruthenium-water system at 298.15 K, for which a critically assessed thermochemical data base is available. Ruthenium exhibits the widest range of known aqueous solution valence states. Known solid anhydrous binary oxides of ruthenium are crystalline RuO/sub 2/, RuO/sub 4/, and possibly RuO/sub 3/ (thin film), and known hydroxides/hydrated oxides (all amorphous) are Ru(OH)/sub 3/ . H/sub 2/O, RuO/sub 2/ . 2H/sub 2/O, RuO/sub 2/ . H/sub 2/O, and a poorly characterized Ru(V) hydrous oxide. Although the other oxides, hydroxides, and hydrous oxides are generally obtained as precipitates from aqueous solutions, they are thermodynamically unstable with regard to RuO/sub 2/(cr) formation. Characterized aqueous species of ruthenium include RuO/sub 4/ (which slowly oxidizes water and which dissociates as a weak acid), RuO/sub 4//sup -/ and RuO/sub 4//sup 2 -/ (which probably contain lesser amounts of RuO/sub 3/(OH)/sub 2//sup -/ and RuO/sub 3/(OH)/sub 2//sup 2 -/, respectively, and other species), Ru(OH)/sub 2//sup 2 +/, Ru/sub 4/(OH)/sub 12//sup 4 +/, Ru(OH)/sub 4/, Ru/sup 3 +/, Ru(OH)/sup …

Subthreshold pion production
This process is relatively well-understood, and one of the aims of subthresold production experiments is to identify other collective effects. Some possible signatures of collective effects are: Production below the 'absolute' threshold; production in excess predictions of nucleon-nucleon models; and a change in the characteristic behavior of the pion spectra as the threshold is crossed. This paper discusses these collective effects especially the last one. (LSP)
