Bubble chamber spectroscopy for chemical analysis: A new concept

Description: A new technique for the detection of trace concentrations of molecules in solution has been developed. This system utilizes the amplification characteristics of a bubble chamber in which energy deposition from laser absorption is monitored. In the experimental set-up, a trace quantity of solute is introduced into liquid propane that is contained in a small (10 ml) stainless steel cell at 120 psi. The propane is superheated by sudden reduction of the cell pressure. Before wall nucleated boiling … more

Recipes for high resolution time-of-flight detectors

Description: The authors discuss the dynamics, construction, implementation and benefits of a time-of-flight (TOF) detector with count rates an order of magnitude higher and resolution three to four times better than that obtainable with a surface barrier detector. The propose use of design criteria for a time-of-flight detector is outlined, and the determination of a TOF detector`s total relative timing error and how this value determines the mass resolution are illustrated using a graphical analysis. They… more

Acquisition and reduction of data obtained from tank 101-SY in-situ ball rheometer

Description: Development of the ball rheometer to measure rheological properties and density of the waste in Hanford Tank 241-SY-101 will be completed around September 1994. This instrument is expected to provide the first-of-its-kind in-situ measurements of the fluid properties of the waste contained within this tank. A mixer pump has been installed in this tank, and this pump has been very successful at mitigating the flammable gas problem associated with Tank 101-SY. The ball rheometer will serve as a di… more

A New Target Concept for Production of Slow Positrons

Description: Slow positrons in the energy range up to a few keV are useful for material sciences and surface studies. The Advanced Photon Source (APS) linear accelerator (linac) was designed to produce 8-mA of 450-MeV positrons. A 200-MeV, 1.7-Ampere electron beam impinges on a 7-mm-thick (2 radiation lengths) tungsten target, resulting in bremsstrahlung pair production of electrons and positrons. The existing target was optimized for high energy positron production, and most slow positrons produced by the … more

Hydrogen Evolution and Sludge Suspension During the Preparation of the First Batch of Sludge at the Savannah River Site

Description: The first batch of High Level Radioactive Sludge for the Defense Waste Processing Facility is being prepared in two 4.9 million liter waste tanks. The preparation involves removing water soluble salts by washing (water addition, sludge suspension, settling and decantation). Sludge suspension is accomplished using long shafted slurry pumps that are mounted on rotating turntables. During the sludge suspension runs in 1993 and 1994, the slurry pumps` cleaning radius was determined to be less than … more

Two Alternate High Gradient Quadrupoles; An Upgraded Tevatron IR and A"Pipe" Design

Description: With the U.S. cancellation of the SSC project, the only large approved hadron accelerator project is CERN's LHC. One of the more critical elements in the performance of a collider is the quadrupole lens at the beam collision points. These quadrupoles, usually referred to as the 'insertion quads' normally form a set of triplets around the interaction region. Their focal power directly affects the luminosity available at the crossing point In order to achieve as high a gradient as possible, the C… more

Power Tests of a String of Magnets Comprising a Full Cell of the Superconducting Super Collider

Description: In this paper we describe the operation and testing of a string of magnets comprising a full cell of the Superconducting Super Collider (SSC). The full cell configuration composed of ten dipoles, two quadrupoles, and three spool pieces is the longest SSC magnet string ever tested. Although the tests of the full cell were undertaken after the SSC project was marked for termination, their completion was deemed necessary and useful to future efforts at other accelerator laboratories utilizing Supe… more

Experience with Palladium Diffusers in Tritium Processing

Description: Hydrogen isotopes are separated from other gases by permeation through palladium and palladium-silver alloy diffusers in the Tritium Facilities at the US Department of Energy Savannah River Site (SRS). Diffusers have provided effective service for almost forty years. This paper is an overview of the operational experience with the various diffuser types that have been employed at SRS. Alternative technologies being developed at SRS for purifying hydrogen isotopes are also discussed.

Improving Water Loop Heat Pump Performance by Using Low Temperature Geothermal Fluid

Description: Water-loop heat pump (WLHP) systems are an important option for space conditioning of commercial buildings. They provide the opportunity of saving energy through heat recovery and thermal balancing when heating and cooling occur simultaneously. WLHP systems typically operate with loop water temperature between 16 C and 32 C. When cooling loads dominate, loop water temperatures are maintained below 32 C by rejecting excess heat with a cooling tower. When heating dominates, loop water temperature… more

Automatic History Matching of Geothermal Field Performance

Description: We have developed inverse modeling capabilities for the multiphase multicomponent numerical simulator TOUGH2 to facilitate automatic history matching and parameter estimation based on data obtained during exploitation of geothermal fields. The ITOUGH2 code allows one to estimate TOUGH2 input parameters based on any type of observation for which a corresponding TOUGH2 output can be calculated. Furthermore, a detailed residual and error analysis is performed, and the uncertainty of model predicti… more

Development of high damage threshold optics for petawatt-class short-pulse lasers

Description: The authors report laser-induced damage threshold measurements on pure and multilayer dielectrics and gold-coated optics at 1053 and 526 nm for pulse durations, {tau}, ranging from 140 fs to 1 ns. Damage thresholds of gold coatings are limited to 500 mJ/cm{sup 2} in the subpicosecond range for 1053-nm pulses. In dielectrics, qualitative differences in the morphology of damage and a departure from the diffusion-dominated {tau}1/2 scaling indicate that damage results from plasma formation and abl… more

Sensing liquid properties with shear-mode resonator sensors

Description: Liquid properties are measured from the changes they induce in the resonant frequency and damping of thicknessshear mode quartz resonators. A smooth-surfaced resonator viscously entrains the contacting fluid and responds to the density-viscosity product. Separation of density and viscosity is accomplished using two devices: one with a smooth surface and one with a corrugated surface that traps fluid. By observing the difference in stored and dissipated energies in the contacting fluid, its non-… more
