General purpose computers in real time (open access)

General purpose computers in real time

I see three main trends in the use of general purpose computers in real time. The first is more processing power. The second is the use of higher speed interconnects between computers (allowing more data to be delivered to the processors). The third is the use of larger programs running in the computers. Although there is still work that needs to be done, I believe that all indications are that the online need for general purpose computers should be available for the SCC and LHC machines. 2 figs.

The glycophorin A assay for somatic cell mutations in humans (open access)

The glycophorin A assay for somatic cell mutations in humans

In this report we briefly review our past experience and some new developments with the GPA assay. Particular emphasis will be placed on two areas that affect the utility of the GPA assay for human population monitoring. The first is our efforts to simplify the GPA assay to make it more generally available for large population studies. The second is to begin to understand some of the characteristics of human hemopoiesis which affect the accumulation and expression of mutant phenotype cells. 11 refs., 4 figs.

Benzene/nitrous oxide flammability in the precipitate hydrolysis process (open access)

Benzene/nitrous oxide flammability in the precipitate hydrolysis process

The HAN (hydroxylamine nitrate) process for destruction of nitrite in precipitate hydrolysis produces nitrous oxide (N2O) gas as one of the products. N2O can form flammable mixtures with benzene which is also present due to radiolysis and hydrolysis of tetraphenylborate. Extensive flame modeling and explosion testing was undertaken to define the minimum oxidant for combustion of N2O/benzene using both nitrogen and carbon dioxide as diluents. The attached memorandum interprets and documents the results of the studies.

Getting maximum information from incomplete data on B yields charmonium-K sub S decays (open access)

Getting maximum information from incomplete data on B yields charmonium-K sub S decays

Tests of CP violation using B decays into CP eigenstates can be improved by using events normally rejected because of incomplete information. A search for lepton asymmetry in decays {Upsilon}(4S) {yields} B + {bar B} {yields} (K{sub S} + J/{psi}) + (lepton {sup {plus minus}} + X) can be improved by including other (c{bar c})K{sub S} events where the (c{bar c}) pair is not bound in a J/{psi} but in some other state like {psi}{prime} or {eta}{sub c} and where the lepton asymmetry is predicted to be the same as for (K{sub S} + J/{psi}), other (c{bar c})K{sub S} events which are not fully reconstructed and (c{bar c})K{sub L} events where the K{sub L} pair is not detected and which are predicted to have the opposite lepton asymmetry from corresponding K{sub S} events. The information from these additional events can give improved statistics if suitable cuts can be found to improve signal/noise. The opposite asymmetry predicted for K{sub L} events can test spurious lepton asymmetries due to systematic errors. 3 refs.

Experimental Studies of Plasma Wake-Field Acceleration and Focusing (open access)

Experimental Studies of Plasma Wake-Field Acceleration and Focusing

More than four years after the initial proposal of the Plasma Wake-field Accelerator (PWFA), it continues to be the object of much investigation, due to the promise of the ultra-high accelerating gradients that can exist in relativistic plasma waves driven in the wake of charged particle beams. These large amplitude plasma wake-fields are of interest in the laboratory, both for the wealth of basic nonlinear plasma wave phenomena which can be studied, as well as for the applications of acceleration of focusing of electrons and positrons in future linear colliders. Plasma wake-field waves are also of importance in nature, due to their possible role in direct cosmic ray acceleration. The purpose of the present work is to review the recent experimental advances made in PWFA research at Argonne National Laboratory, in which many interesting beam and plasma phenomena have been observed. Emphasis is given to discussion of the nonlinear aspects of the PWFA beam-plasma interaction. 29 refs., 13 figs.

Laboratory studies of the behavior of undissolved solids in both pulsed and packed column extraction systems (open access)

Laboratory studies of the behavior of undissolved solids in both pulsed and packed column extraction systems

A substantial fraction of the finely divided undissolved solid material found in nuclear fuel reprocessing dissolver-product solutions is hydrophobic and tends to ``seek`` any organic-aqueous interface existing within countercurrent liquid-liquid extraction systems. While passing through pulsed-type columns this material is swept out of the aqueous phase by the combined surface area of the tiny bubbles of dispersed phase. Because these bubbles have a net velocity towards the end of the column where the nominal interface is located, the solids are swept in that direction too. These solids tend to gather in a three-phase ``crud`` layer at the nominal interface point. At equilibrium, about the same amount breaks off from the crud layer and escapes into the liquid exiting from that end of the column as enters it from the other side. If large enough, the crud layer can even interfere with interface detection and control equipment. In packed-column extraction systems, an additional problem is that feed solids can accumulate within the packing material to the point that the column `` floods`` or even totally plugs. The keys to preventing solids-related problems is the correct choice of interface level, and with packed columns, the addition of a ``pulsing leg`` at the …

Modifications to Replacement Costs System (open access)

Modifications to Replacement Costs System

The purpose of this memorandum is to document the improvements and modifications made to the Replacement Costs of Crude Oil (REPCO) Supply Analysis System. While some of this work was performed under our previous support contract to DOE/ASFE, we are presenting all modifications and improvements are presented here for completeness. The memo primarily documents revisions made to the Lower-48 Onshore Model. Revisions and modifications made to other components and models in the REPCO system which are documented elsewhere are only highlighted in this memo. Generally, the modifications made to the Lower-48 Onshore Model reflect changes that have occurred in domestic drilling, oil field costs, and reserves since 1982, the date of the most recent available data used for the original Replacement Costs report, published in 1985.

Program status 4. quarter -- FY 1989: Fusion technology development

The ARIES-I design is nearing completion. The ARIES-II design work will begin soon and will be based on an advanced physics DT tokamak operating in the second stability regime. The ARIES-I blanket design team has selected the 5 MPa helium-cooled design as the reference blanket for study. Beryllium neutron multiplier will be used together with an advanced super-critical steam cycle for power conversion. Model ICRF tetrode tube anodes demonstrated the equivalent of plate dissipation, exceeding expectations. Full size tubes are being constructed for testing at JAERI. International fusion nuclear data cooperation activities continued to expand. The exposure of 12 well-characterized graphite tiles in the divertor region of DIII-D continues. The conceptual design of a mechanism to insert material samples into the DIII-D divertor is nearing completion. Finally, the data on manganese-stabilized austenitic steels that was obtained and compiled last quarter was prepared for presentation to the ITER team.
