Establishment and maintenance of a coal sample bank and data base

In this Project Status Report for 7/9/89--10/8/89, results of a comparative study of coal sample deterioration in several container types were presented. In April 1990, one year after the initial analyses, the set of analyses was repeated on the most important container types. The new results are included in Table 2. During the current reporting period a total of 42 data printouts were distributed. In addition, 7 special data requests were fulfilled by either search/sort and printout or creation of a data disk, resulting in distribution of limited information on 2083 samples. Several preliminary requests for Sample Bank and Data Base information and price quotations have also been handled.

Finite element analysis of the SDC barrel and endcap calorimeters (open access)

Finite element analysis of the SDC barrel and endcap calorimeters

In designing the SCD barrel and endcap calorimeters, the inter-module connecting forces must be known in order to determine the required size and number of connecting links between modules, and in order to understand how individual modules will be affected by these forces when assembled to form a full barrel and endcap. The connecting forces were found by analyzing three-dimensional Finite Element Models of both the barrel and endcap. This paper is divided into two parts, the first part will describe in detail the results of the barrel analysis and the second part will describe the results obtained from the endcap analysis. A similar approach was used in constructing the models for both analysis.

Quadrupole mass-filter sensitivities of H/sub 2/, HD, D/sub 2/, and T/sub 2/, and the kinetics of. beta. -particle induced exchange between H/sub 2/, D/sub 2/, and T/sub 2/ at 25. 4/sup 0/C (open access)

Quadrupole mass-filter sensitivities of H/sub 2/, HD, D/sub 2/, and T/sub 2/, and the kinetics of. beta. -particle induced exchange between H/sub 2/, D/sub 2/, and T/sub 2/ at 25. 4/sup 0/C

We have constructed a quadrupole-mass filter system to measure the equilibrium constants and rates of reaction of the ..beta..-particle-induced exchanges between H/sub 2/, D/sub 2/, and T/sub 2/ at cryogenic temperatures. Even with careful calibration experiments at 25.4/sup 0/C, we could not completely remove the mass discrimination inherent in our method. We estimate the accuracy of our mixture analyses to be +-2.2% in the D/sub 2/-DT-T/sub 2/ system, and +-9% in the H/sub 2/-HT-T/sub 2/ system. Preliminary kinetic experiments showed that the time to reach equilibrium in the exchange H/sub 2/ + T/sub 2/ = 2HT is 7 to 14 h. The equivalent time interval in the exchange D/sub 2/ + T/sub 2/ = 2DT is 3 to 7 h. This measured isotope effect of two can be used to predict the rates of the DT exchange from the HT rates in the literature.

AIRBLAST OVERPRESSURE AND DYNAMIC PRESSURE OVER VARIOUS SURFACES (open access)

AIRBLAST OVERPRESSURE AND DYNAMIC PRESSURE OVER VARIOUS SURFACES

Static overpressure and dynamic pressure versus time over surfaces processing different physical properties were measured on two tower shots, 6 and 12. On Shot 12, three surfaces were provided: the natural desert, a water surface consisting of a flooded area, and an asphalt surface. On Shot 6, desert and asphalt areas only were available. There were 123 channels of instrumentation installed for Shot 12, and 24 for Shot 6. From the data, a system of wave-form classification was devised for overpressure and dynamic-pressure- versus-time measurements. Incorporation of this system into data analysios indicates that it is possible for an ideal peak pressure to be identified with a nonideal wave form. Introducing both variables, wave form and peak pressure, into analyses reduces ambiguioties associoated with comparing results of different nuclear tests. The data show the effect of the nature of the surface upon airblast phenomena from a nuclear explosion. The effects of surface conditions upon shock phenomena are made more understandable by a review of temperature computatioons, using shock wave parameters in addition to an analysis based upon the arrioval time of the thermal pulse. A phenomenological discussion of precursor formation is presented, and comparisons are made using data from all …

A PULSED EDDY CURRENT TEST SYSTEM USING REFLECTED FIELDS (open access)

A PULSED EDDY CURRENT TEST SYSTEM USING REFLECTED FIELDS

An eddy current test system is described in which the test information is detected as a series of fields reflected from the metal surface and interior. Pulsed electromagnetic fields are caused to impinge upon the test specimen. These fields are restricted to a small cross sectional area over a path in space long enough to be useful for test purposes by devices called mask-apenture assemblies. This approach provides a number of advantages over conventional eddy current methods of comparable capabilities, including superior surface resolution, a reduction in circuit complexity, and an improvement in stability and reliability. Various applications and test results are discussed. (auth)

Multi-temperature gas chromatography using isothermal columns in series. Technical report (open access)

Multi-temperature gas chromatography using isothermal columns in series. Technical report

A computer-controlled three-oven gas chromatograph having a multi-position stream-switching valve has been used first to divide a wide-boiling mixture of n-alkanes into three cuts and then to fractionate each cut using a packed column at a different temperature. After initial injection of the sample into the highest temperature column, the low boilers were switched to a low temperature oven. Then, the mid-boilers were switched to a column at an intermediate temperature. For routine repetitive analyses, the multi-oven approach offers an attractive alternative.

Application of automated deduction to the search for single axioms for exponent groups (open access)

Application of automated deduction to the search for single axioms for exponent groups

We present new results in axiomatic group theory obtained by using automated deduction programs. The results include single axioms, some with the identity and others without, for groups of exponents 3, 4, 5 and 7, and a general form for single axioms for groups of odd exponent. The results were obtained by using the programs in three separate ways: as a symbolic calculator, to search for proofs,and to search for couterexamples. We also touch on relations between logic programming and automated reasoning.

Thyratron characteristics under high di/dt and high-repetition-rate operation (open access)

Thyratron characteristics under high di/dt and high-repetition-rate operation

Power conditioning systems for high peak and average power, high repetition rate discharge excited lasers involve operation of modulator components in unconventional regimes. Reliable operation of switches and energy storage elements under high voltage and high di/dt conditions is a pacing item for laser development at the present time. To test and evaluate these components a Modulator Component Test Facility (MCTF) was constructed. The MCTF consists of a command charge system, energy storage capacitors, thyratron switch with inverse thyratron protection, and a resistive load. The modulator has initially been operated at voltages up to 60 kV at 600 Hz. Voltage, current, and calorimetric diagnostics are provided for major modulator components. Measurements of thyratron characteristics under high di/dt operation are presented. Commutation energy loss and di/dt have been measured as functions of the tube hydrogen pressure.

Heating by the Raman instability (open access)

Heating by the Raman instability

Computer simulations are presented of the reflection and heating due to stimulated Raman backscatter of intense laser light in large regions of underdense plasma. The heated electron distribution is found to be approximately a Maxwellian of temperature (m/sub e//2)v/sub p//sup 2/, where v/sub p/ is the phase velocity of the electron plasma wave. A simple model of the reflection is presented. Raman may cause a pre-heat problem with large laser fusion reactor targets.
