A 1. 5--4 Kelvin detachable cold-sample transfer system: Application to inertially confined fusion with spin-polarized hydrogens fuels

A compact cold-transfer apparatus for engaging and retrieving samples at liquid helium temperatures (1.5--4K), maintaining the samples at such temperatures for periods of hours, and subsequently inserting them in diverse apparatuses followed by disengagement, is described. The properties of several thermal radiation-insulating shrouds, necessary for very low sample temperatures, are presented. The immediate intended application is transportable target-shells containing highly spin-polarized deuterons in solid HD or D{sub 2} for inertially confined fusion (ICF) experiments. The system is also valuable for unpolarized high-density fusion fuels, as well as for other applications which are discussed. 9 refs., 6 figs.

3 Dimensional radiation transport in dispersive media (open access)

3 Dimensional radiation transport in dispersive media

In plasmas the collective motion of free electrons affects the propagation of radiation by bending the light ray trajectory. The closer the light wave frequency is to the electron plasma frequency in value, the more pronounced the effect. We will present the results of radiation transport calculations in 3 spatial dimensions in the refractive plasma environment and compare the calculation to one done where the ray bending has been neglected (straight line ray paths). We also present the numerical method used for the refractive transport. 4 refs., 5 figs.

A 4. pi. tracking TPC magnetic spectrometer for RHIC (open access)

A 4. pi. tracking TPC magnetic spectrometer for RHIC

The primary physics objective of the 4{pi} TPC magnetic spectrometer proposal is to search for the Quark-Gluon Plasma. In previous workshops we have discussed what the possible hadronic signatures of such a state of matter would be. Succinctly, the QGP is a direct prediction of non-perturbative QCD. Therefore the question of the existence of this new state of matter bears directly on the validity of non-perturbative QCD. However, since non-perturbative QCD has never been established, it is apparent that what may await us is a host of new phenomena that will go beyond the standard model.

A 15 MeV proton diagnostic for DIII-D (open access)

A 15 MeV proton diagnostic for DIII-D

A 15 MeV proton diagnostic that is patterned after the ASDEX proton probe is presently being fabricated for the DIII-D tokamak. A bellows assembly inserts a silicon detector into the vacuum for plasma operation and retracts it for baking. The detector preamplifier is situated in a reentrant tube (at atmosphere) beside the detector; electrically, the whole assembly is referenced to vessel potential. Orbit calculations in realistic magnetic field geometries predict a proton detection efficiency of O(10{sup {minus}7}). The diagnostic will be used for burnup studies at high {beta} and particle transport studies in the H-mode. 25 refs., 4 figs.

24 Hour pumping test of production well 905-120P

As part of the Savannah River Site (SRS) Aquifer Characterization Program, the Environmental Sciences Section (ESS) of the Savannah River Laboratory (SRL) is attempting to determine the water transmitting characteristics of the different aquifer units underlying the SRS by conducting single well pumping tests on wells installed as part of the SRS Baseline Hydrogeologic Investigation. In April 1990, while performing the single well pumping test, an opportunity became available to collect data on aquifer properties utilizing a production well and observation wells. At this time the US Army Corps of Engineers (COE) was completing a new production well (well 905-120P) in P-Area. This well, located in close proximity to well cluster P-24, was to undergo a 24-hour performance test by the COE. ESS arranged with the subcontractor working on the Single Well pumping Test project.

50 kA, 50 kV DC international and switching systems for the Los Alamos ZTH experiment

Los Alamos National Laboratory has completed the engineering design and development for the high power electrical switching networks for the ZTH experiment. ZTH is Reversed Field Pinch (RFP) plasma experiment with a 4 MA plasma current capability. Power to the ohmic heating (OH), equilibrium field (EF), and toroidal field (TF) coils will be provided from a 1.43 GVA turbo-alternator, which has over 600 MJ of extractable energy. The DC interrupting switch will handle 2.4 GVA, 150 MJ during initial machine operations. An additional 150 to 200 MJ are required for flat-topping the plasma current. A new ultra-high power switch, designed and tested at Los Alamos, will be used to reconfigure the power supply connections so that the supplies can be switched from parallel to series operation. In this manner, the same supplies can be used to charge and then flat-top the OH coils. The inexpensive cost of these switches results in significant economy of power supplies and systems. Detailed engineering information will be presented for the family of 25 kA and 50 kA, 50kV fast isolation and transfer switches, including testing of special water-cooled units capable of 50,000 amperes continuous duty. Similarly, detailed engineering data will be provided for the …

1990 update for the applications guide to pedestrian SNM (special nuclear material) monitors (open access)

1990 update for the applications guide to pedestrian SNM (special nuclear material) monitors

The physical principles of special nuclear material (SNM) monitoring have not changed in the five years since the writing of the Los Alamos report, An Applications Guide to Pedestrian SNM Monitors (AL-10633-MS).'' However, during those years, there has been evidence for the start of significant change in the practice of SNM monitoring. Recently revised Department of Energy orders allow flexibility in selecting material-control measures by addressing both abrupt and protracted theft or diversion of SNM and by grading the material according to its attractiveness. Other new guideline on how to apply, test, and maintain SNM monitors and metal detectors are becoming available from the American Society for Testing and Materials. But perhaps the most noticeable change to the Applications Guide is in Part 3, the catalog of commercial pedestrian SNM monitors, where many obsolete entries have been replaced by new monitors. This update for the Applications Guide catalogs new pedestrian SNM monitors and discusses what is new and what is changing in the practice of SNM monitoring. 31 refs., 11 figs.

1990 yearly calibration of Pacific Northwest Laboratory's gross-gamma borehole geophysical logging system (open access)

1990 yearly calibration of Pacific Northwest Laboratory's gross-gamma borehole geophysical logging system

This report describes the 1990 yearly calibration of a gross-gamma geophysical pulse logging system owned by the US Department of Energy (DOE) and operated by Pacific Northwest Laboratory (PNL). The calibration was conducted to permit the continued use of this system for geological and hydrologic studies associated with remedial investigation at the Hanford Site. Primary calibrations to equivalent uranium units were conducted in borehole model standards that were recently moved to the Hanford Site from the DOE field calibration facility in Spokane, Washington. The calibrations were performed in borehole models SBL/SBH and SBA/SBB, which contain low equivalent-uranium concentrations. The integrity of the system throughout the previous year from gamma-ray monitoring was demonstrated using the before- and after-logging field calibration readings with the field source in calibration Positions 1 and 2. Most of the Position 1 readings are within an 8% limit that is set by the governing PNL technical reference procedure as a critical value above which the instrument is considered suspect. Many of the Position 2 readings exceed the 8% limit; however, the fluctuation was traced to field-source geometry variability that affected Position 1 count rates by up to 6% and Position 2 count rates by as much as …

Presented in this report is the interpretation of the hydrogeologic environment at the 2101-M Pond, located in the 200-East Area of the Hanford Site. This information and its accompanying interpretation were derived from sampling and testing activities associated with the installation of four ground-water monitoring wells, in addition to data gathered from several previously existing wells. The new monitoring wells were installed as part of a groundwater monitoring program initiated in 1988. The four new monitoring wells were installed around the 2101-M Pond between May 23 and August 27, 1988. Geologic sampling, aquifer testing, and initial ground-water sampling were performed during the installation of these wells. Laboratory analyses of the sediment samples for particle size, calcium carbonate content, and selected natural and contaminant constituents were performed.

Much more extensive and precise and data have been taken since the original discovery. This body of data is now quite consistent and many of the features of the original EMC effect'' remain intact. There have been a variety of theoretical explanations of the data, but none are totally compelling. The deep-inelastic-scattering (DIS) data for the ratio of F{sub 2}{sup Fe}(x) in iron to F{sub 2}{sup D}(x) in deuterium are given for the region 0.03 {le} {times} {le} {approximately} 1.0.
