Xe/D sub 2 cross-section ratios at low X sub Bj from muon scattering at 490 GeV/c
First measurements from the E665 experiment at Fermilab on the relative cross-sections of 490 GeV/c muons scattered from deuterium and xenon targets are presented. The scattered muons were in the kinetic range Q{sup 2} > 0.1(GeV/c){sup 2} and very low x{sub Bj} (0.001 < x{sub Bj} < 0.1). Triggering on events in this kinematic region was accomplished with a special Small Angle Trigger which projected individual beam muons to form a veto region 30 meters from the target. Using this trigger, muons with scattered angles as small as 0.5 milliradians were detected. 8 refs., 6 figs.

{Xi} ({Omega}) production in Pb + Pb collisions at 158 GeV/c
Using the NA49 main TPC, the central production of ({Xi} + {bar {Xi}}) hyperons has been measured in CERN SPS Pb on Pb collisions at 158 GeV/c. The preliminary ({Xi} + {bar {Xi}})/ ({Lambda} + {bar {Lambda}}) ratio, studied at 2.0 < y < 2.6 and 1 < p{sub T} < 3 GeV/c, equals {approximately} (13 {+-} 4)% (systematic error only). It is compatible, within errors, with the previously obtained ratios for central S+S, S+W, and S+Au collisions. The fit to the transferse momentum distribution resulted in an inverse slope parameter T of 297 MeV. At this level of statistics we do not see any noticeable enhancement of hyperon production with the increased volume (and, possibly, degree of equilibration) of the system from S+S to Pb+Pb. This result is unexpected and counterintuitive, and should be further investigated. If confirmed, it will have a significant impact on our understanding of mechanisms leading to the enhanced strangeness production in heavy ion collisions.

XUV postionization of fragments of photodissociated C{sub 60}
We report experimental evidence for the loss of neutral C, C{sub 2}, C{sub 3}, and C{sub 4} from photoexcited C{sub 60} and C{sub 70}. These species are detected by postionization with XUV radiation formed by four-wave mixing in Kr vapor. The fragments have been detected in the nascent distribution (i.e., before total disintegration of the fullerene-size molecular entities). A resonant autoionization transition in C atom has yielded an upper limit to the translational energy release for dissociation into C atoms. The detection of these products gives new insight into the fragmentation mechanism of fullerenes.

Yucca Mountain Milestone
The Department of Energy project to determine if the Yucca Mountain site in Nevada is suitable for geologic disposal of high-level nuclear waste reached a major milestone in late April when a 25-foot-diameter tunnel boring machine ``holed through'' completing a five-mile-long, horseshoe-shaped excavation through the mountain. When the cutting-head of the giant machine broke through to daylight at the tunnel's south portal, it ended a 2 1/2-year excavation through the mountain that was completed ahead of schedule and with an outstanding safety record. Video of the event was transmitted live by satellite to Washington, DC, where it was watched by Secretary of Energy Frederico Pena and other high-level DOE officials, signifying the importance of the project's mission to find a repository for high-level nuclear waste and spent nuclear fuel produced by nuclear power plants. This critical undertaking is being performed by DOE's Office of Civilian Radioactive Waste Management (OCRWM). The tunnel is the major feature of the Exploratory Studies Facility (ESF), which serves as an underground laboratory for engineers and scientists to help determine if Yucca Mountain is suitable to serve as a repository for the safe disposal of high-level nuclear waste. Morrison Knudsen's Environmental/Government Group is providing design and …

The Yucca Mountain Project drift scale test
The Yucca Mountain Project is currently evaluating the coupled thermal-mechanical-hydrological-chemical (TMHC) response of the potential repository host rock through an in situ thermal testing program. A drift scale test (DST) was constructed during 1997 and heaters were turned on in December 1997. The DST includes nine canister-sized containers with thirty operating heaters each located within the heated drift (HD) and fifty wing heaters located in boreholes in both ribs with a total power output of nominally 210kW. A total of 147 boreholes (combined length of 3.3 km) houses most of the over 3700 TMHC sensors connected with 201 km of cabling to a central data acquisition system. The DST is located in the Exploratory Studies Facility in a 5-m diameter drift approximately 50 m in length. Heating will last up to four years and cooling will last another four years. The rock mass surrounding the DST will experience a harsh thermal environment with rock surface temperatures expected to reach a maximum of about 200 C. This paper describes the process of designing the DST. The first 38 m of the 50-m long Heated Drift (HD) is dedicated to collection of data that will lead to a better understanding of the …

Yucca Mountain Site Characterization Project bibliography, 1992--1994. Supplement 4
Following a reorganization of the Office of Civilian Radioactive Waste Management in 1990, the Yucca Mountain Project was renamed Yucca Mountain Site Characterization Project. The title of this bibliography was also changed to Yucca Mountain Site Characterization Project Bibliography. Prior to August 5, 1988, this project was called the Nevada Nuclear Waste Storage Investigations. This bibliography contains information on this ongoing project that was added to the Department of Energy`s Energy Science and Technology Database from January 1, 1992, through December 31, 1993. The bibliography is categorized by principal project participating organization. Participant-sponsored subcontractor reports, papers, and articles are included in the sponsoring organization`s list. Another section contains information about publications on the Energy Science and Technology Database that were not sponsored by the project but have some relevance to it. Earlier information on this project can be found in the first bibliography DOE/TIC-3406, which covers 1977--1985, and its three supplements DOE/OSTI-3406(Suppl.1), DOE/OSTI-3406(Suppl.2), and DOE/OSTI-3406(Suppl.3), which cover information obtained during 1986--1987, 1988--1989, and 1990--1991, respectively. All entries in the bibliographies are searchable online on the NNW database file. This file can be accessed through the Integrated Technical Information System (ITIS) of the US Department of Energy (DOE).

YUCCA MOUNTAIN SITE CHARACTERIZATION PROJECT EAST-WEST DRIFT SYSTEM SAFETY ANALYSIS
The purpose of this analysis is to systematically identify and evaluate hazards related to the design of the Yucca Mountain Project Exploratory Studies Facility (ESF) East-West Cross Drift. This analysis builds upon prior ESF System Safety Analyses and incorporates TS Main Drift scenarios, where applicable, into the East-West Drift scenarios. This System Safety Analysis (SSA) focuses on the personnel safety and health hazards associated with the engineered design of the East-West Drift. The analysis also evaluates other aspects of the East-West Drift, including purchased equipment (e.g., scientific mapping platform) or Systems/Structures/Components (SSCs) and out-of-tolerance conditions. In addition to recommending design mitigation features, the analysis identifies the potential need for procedures, training, or Job Safety Analyses (JSAs). The inclusion of this information in the SSA is intended to assist the organization(s) (e.g., constructor, Safety and Health, design) responsible for these aspects of the East-West Drift in evaluating personnel hazards and augment the information developed by these organizations. The SSA is an integral part of the systems engineering process, whereby safety is considered during planning, design, testing, and construction. A largely qualitative approach is used which incorporates operating experiences and recommendations from vendors, the constructor and the operating contractor. The risk assessment …

Z-Area Saltstone Disposal Facility groundwater monitoring report. First quarter 1995
The three monitoring wells at the Z-Area Saltstone Disposal Facility, ZBG 1, 1A, and 2, are sampled quarterly as part of the Savannah River Site Groundwater Monitoring Program and to comply with conditions of the facility`s Industrial Waste Permit IWP-217, issued by the South Carolina Department of Health and Environmental Control (SCDHEC). During first quarter 1995, samples from wells ZBG 1 and 2 were analyzed for selected inorganic constituents, volatile organic compounds, selected radionuclides, and other constituents. Well ZBG 1A was dry and could not be sampled. None of the wells contained constituents above SCDHEC proposed groundwater monitoring standards, final Primary Drinking Water Standards, or flagging criteria. In previous quarters, wells ZBG 1 and 2 contained slightly elevated levels of tritium, similar to the tritium levels detected before Z Area began radioactive operations.

Z-Pinch Generated X-Rays Demonstrate Indirect-Drive ICF Potential
Hohlraums (measuring 6-mm in diameter by 7-mm in height) have been heated by x-rays from a z-pinch. Over measured x-ray input powers P of 0.7 to 13 TW, the hohlraum radiation temperature T increases from {approximately}55 to {approximately}130 eV, and is in agreement with the Planckian relation P-T{sup 4}. The results suggest that indirect-drive ICF studies involving NIF relevant pulse shapes and <2-mm diameter capsules can he studied using this arrangement.

Zeolite Membranes for Gas Separations
Silicalite-1, a pure silica zeolite, was deposited on a tubular, asymmetric, {gamma}-alumina support. Single gas permeation experiments with N{sub 2}, CH{sub 4}, and CO{sub 2} were carried out on the membrane. Separation experiments for N{sub 2}/CH{sub 4} mixtures were also conducted. Single-gas permeation of H{sub 2} and separation of H{sub 2}/SF{sub 6} mixture were also carried out with the membrane. Composite membranes of silicalite and Ni-SAPO-34 were also fabricated, but no CO{sub 2}/H{sub 2} selectivity was found. It is proposed to use these membranes for methanol synthesis and separation, and for separating H{sub 2} from gasification products for use as fuel cell fuel, etc.
