Establishment and maintenance of a coal sample bank and data base

Description: During the current reporting period a total of 139 samples (46 DOE Sample Bank samples and 93 other Penn State samples) of various sizes were distributed. Sixty-three of the samples were distributed to DOE or its contractors; 76 were distributed to other agencies. A total of 88 data printouts were distributed. In addition, seven special data requests were fulfilled by either search/sort and printout or creation of a data disk. Several preliminary requests for Sample Bank and Data Base informati… more

Updated summary of measurements and calculations of neutron and gamma-ray emission spectra from spheres pusled with 14-MeV neutrons: Revision 1

Description: New measurements of the neutron and gamma-ray emission spectra from materials of interest to thermonuclear reactors with a 14 MeV neutron source were done during 1986 and 1987. These measurements characterized by better resolution than those reported in the Summary published in 1982, were performed using the pulsed sphere and time-of-flight techniques. The detector used in these measurements was a NE-213 cylinder, 5.08 cm in diameter by 5.08 cm thick. The new measurements include the following … more

Permeability Changes in Coal Resulting From Gas Desorption. First Quarterly Report, August 16, 1989--November 15, 1989

Description: Sampling Procedure: This project requires a carefully coordinated sample preparation procedure that will ensure that specimens of the proper size and physical characteristics are available for the various measurement methods used. Coherent blocks of coal will be collected in the field, with subsamples being removed in the lab by 1 inch-diameter core drill. At least 5 separate cores will be drilled from each block. Coal blocks sampled in the field will be approximately 10 inches (times) 10 inche… more

Flow Sizing the Cryosystem Valves

Description: The liquid argon dewar and the three cryostats which contain the modules of the D-Zero detector are cooled and maintained at a low pressure equilibrium by the use of liquid nitrogen cooling loops. The dewar has one vacuum jacketed valve at the inlet of the cooling loop and one at the outlet. Each cryostat has two inlet valves, one for the cooldown loops and one for the operating loops. in addition to an outlet valve. The flow rate of the liquid nitrogen, and hence the valve sizes and correspond… more

Experimental support for KrF laser modeling. Final report

Description: This paper is the final report for a project to do characterization studies on the KrF laser system. The project did experimental work on KrF lasers in support of modeling studies, with the objective being to see if this technology could be competitive for use in the ICF program. This program has provided LANL with data critical for their model development. Section 2 describes the laser extraction experiments together with the calibration of the diagnostics and the re-examination of the analysi… more

Workshop on Calorimetery for the Superconducting Super Collider

Description: The international workshop brought together 170 participants to further develop the SSC design and performance specifications of the LAr, Gas, Scintillation, Silicon, and Warm Liquid calorimeter technologies, and to develop the general topics of Requirements, Simulation, and Electronics. Progress was made across a broad front in all areas; at the feasibility level for some and In the fine structure for others. The meeting established areas of agreement, provided some general direction, and help… more

Rapid heating tensile tests of hydrogen-charged high-energy-rate-forged 316L stainless steel

Description: 316L stainless steel is a candidate material for construction of equipment that will be exposed to tritium. Proper design of the equipment will require an understanding of how tritium and its decay product helium affect mechanical properties. This memorandum describes results of rapid heating tensile testing of hydrogen-charged specimens of high-energy-rate-forged (HERF) 316L stainless steel. These results provide a data base for comparison with uncharged and tritium-charged-and-aged specimens … more

Program plan for TNX Area groundwater characterization wells

Description: The TNX Area post-Cretaceous hydrogeological section consists of an unconfined aquifer in recent to Pliestocene age sediments and a confined aquifer in tertiary aged sediments. The unconfined aquifer is a local water bearing reservoir and will not be correlated to a specific stratigraphic unit at this time. Depth to the water table ranges from 25 feet at the New TNX Seepage Basin to 50 feet at the Old TNX Seepage Basin. The unconfined aquifer is 45--50 feet thick and outcrops in the swamp to th… more

Direct catalytic conversion of methane and light hydrocarbon gases. Quarterly report No. 10, January 1--March 31, 1989

Description: The goal of this research is to develop catalysts that directly convert methane and light hydrocarbons to intermediates that later can be converted to either liquid fuels or value-added chemicals, as economics dictate. In this reporting period, we have utilized samples of magnesia differing in their pretreatment temperature. Both the hydrido-ruthenium complex H{sub 4}Ru{sub 4}(CO){sub 12} and its reaction product with triethyl aluminum were reacted with these samples. The two ruthenium clusters… more
