Programmable multi-timer for TRU waste analysis applications
A programmable, multiple-function timing module has been developed for use in transuranic (TRU) waste analysis applications at the Idaho National Engineering Laboratory. The Programmable Multi-Timer (PRMT) is an expanded version of a module originally built for accelerator-based active photon interrogation experiments. During the course of the experiments, it became obvious that a more versatile timer was needed to meet several unforeseen requirements. The PRMT was designed to meet the new requirements and to serve as a general-purpose timing module for other applications.

Prairie Canal Well No. 1, Calcasieu Parish, Louisiana. Volume 1. Completion and testing. Final report
The Prairie Canal Company, Inc. Well No. 1, approximately 8 miles south of the city of Lake Charles, Louisiana, was tested through the annulus between 5-1/2 inch casing and 2-3/8 inch tubing. The interval tested was from 14,782 to 14,820 feet. The geological section was the Hackberry Sand, a member of the Oligocene Frio formation. Produced water was injected into a disposal well which was perforated in several Miocene Sands from 3070 to 4600 feet. Original plans were to test a section of the Hackberry sand from 14,976 to 15,024 feet. This primary zone, however, produced a large amount of sand, shale, gravel, and rocks during early flow periods and was abandoned in favor of the secondary zone. Four pressure drawdown flow tests and three pressure buildup tests were conducted during a 12-day period. A total of 36,505 barrels of water was produced. The highest sustained flow rate was approximately 7100 BWPD. The gas-to-water ratio, measured during testing, ranged from 41 to 50 SCF/BBL. There is disagreement as to the saturation value of the reservoir brine, which may be between 43.3 and 49.7 SCF/BBL. The methane content of the flare line gas averaged 88.4 mole percent. The CO/sub 2/ content …

Optimization of microchannel plate multipliers for tracking minimum-ionizing particles
The progress in development of special Microchannel Plates for particle tracking is reported. The requirements of (1) high spatial resolution; (2) high density of information; and (3) rate capability were found to be satisfied in a thick Microchannel Plate with a CsI coating operating in a focusing magnetic field. The measurements of the Microchannel Plate detection efficiency, gain and noise are presented for several detectors. The pictures of the passage and interaction of the high energy charged particles inside the detector are shown.

Vacuum system problems of EBT: a steady-state fusion experiment
Many of the vacuum problems faced by EBT will soon be shared by other plasma devices as high-power microwave systems and long pulse lengths become more common. The solutions used on EBT (such as the raised lip with elastomer seal) are not unique; however, experience has shown that microwave-compatible designs must be carefully thought out. All details of the vacuum must be carefully thought out. All details of the vacuum must be carefully screened in advance to insure that microwaves do not leak into pumps or diagnostics where they can cause major damage. Sputter coating, which even now is noticeably present in most pulsed plasma systems, becomes much worse as systems approach steady state. And finally, radiation degradation of components which is presently a minor problem will become significant on high-power microwave-fed devices, such as EBT-P.

Shallow hydrothermal regime of the East Brawley and Glamis known geothermal resource areas, Salton Trough, California
Thermal gradients and thermal conductivities were obtained in real time using an in situ heat-flow technique in 15 shallow (90 to 150 m) wells drilled between Brawley and Glamis in the Imperial Valley, Southern California. The in situ measurements were supplemented by follow-up conventional temperature logs in seven of the wells and by laboratory measurements of thermal conductivity on drill cuttings. The deltaic sedimentary material comprising the upper approx. 100 m of the Salton Trough generally is poorly sorted and high in quartz resulting in quite high thermal conductivities (averaging 2.0 Wm/sup -1/ K/sup -1/ as opposed to 1.2 to 1.7 for typical alluvium). A broad heat-flow anomaly with maximum of about 200 mWm/sup -2/ (approx. 5 HFU) is centered between Glamis and East Brawley and is superimposed on a regional heat-flow high in excess of 100 mWm/sup -2/ (> 2.5 HFU). The heat-flow high corresponds with a gravity maximum and partially with a minimum in electrical resistivity, suggesting the presence of a hydrothermal system at depth in this area.

Ion-beam depth-profiling studies of leached glasses
Ion-beam depth-profiling was carried out on three different glasses leached (or hydrated) in deionized water using /sup 1/H(/sup 19/F,..cap alpha gamma..)/sup 16/O nuclear reaction, secondary ion mass spectrometry (SIMS) and sputter-induced photon spectrometry (SIPS) techniques. The depth-profiles show an interdiffusion mechanism in which the sodium ions in the glass are depleted and replaced by hydrogen (H/sup +/) or hydronium (H/sub 3/O/sup +/) ions from the solution. The leaching behavior does not show significant difference whether the glass surface is fractured or polished. Problems of mobile ion migration caused by ion bombardment and loss of hydrogen during analysis are discussed.

Size distribution of autotrophy and microheterotrophy in reservoirs: implications for foodweb structure
Particle size is a primary determinant of resources available to consumers and of the efficiency of energy transfer through planktonic food chains. Dual radioisotopic labeling (with /sup 14/C-bicarbonate and /sup 3/H-acetate) and size fractionation of naturally-occurring phytoplankton-bacterioplankton assemblages were employed to examine the particle size distributions of planktonic autotrophy and microheterotrophy in four limnologically-dissimilar US reservoirs (Lake Mead, Arizona-Nevada, oligo-mesotrophic; Broken Bow Lake, Oklahoma, mesotrophic; Lake Texoma, Oklahoma-Texas, eutrophic; and Normandy Lake, Tennessee, eutrophic). Small nano- and ultraphytoplankton (< 8.0 ..mu..m) and free-living bacteria (< 3.0 ..mu..m) were primarly responsible for planktonic autotrophy and microheterotrophy, respecitvely, even in eutrophic conditions. Zooplankton grazing experiments indicated that (1) most grazing pressure occurs on 3.0 to 8.0 ..mu..m particles, (2) grazer limitation of the occurrence of attached bacteria amd microbial-detrital aggregates is unlikely, and (3) free-living bacteria are inefficiently harvested, relative to algae, by most reservoir zooplankton. Relative to autorophy, the microheterotrophic conversion of allochthonous dissolved organic matter and algal excretion products to bacterial biomass appears unlikely to be a significant source of organic carbon for planktonic grazers in most reservoirs.

Accomplishments of the Small-Hydro Outreach Program. Final report
In September 1980, the Small-Hydro Outreach Program was established by the US Department of Energy and the California Department of Water Resources to promote and encourage the development of small hydroelectric power projects as a renewable energy resource in California. Projects at existing hydraulic structures were particularly emphasized since they have less potential for adverse effect on the environment. Before the outreach program was established, the task force had compiled a list of potential hydro facilities at existing hydraulic structures. The efforts of the outreach program were first aimed at informing the owners of the potential and development procedures for their sites. When the small hydro rush snowballed in the Spring of 1981, numerous requests for information on small hydro development on free flowing streams where no diversions or hydraulic structures existed were received. The outreach program was modified at that time to consider small hydro projects at both undeveloped and developed sites. The main accomplishments of the outreach program have been the publication of Small-Scale Hydro News, conducting a Small-Scale Hydro Workshop and the distribution of bulletins, reports, and pamphlets to reach over 3000 persons interested in small hydro development.

System component compatibility and R-114 stability. Volume II. Final report
High temperature stability-compatibility studies of R-114 refrigerant and proposed Sperry Geothermal System components were performed. The R-114 refrigerant, geothermal brine, and ten lubricants were tested in the presence of five metals, eight metal alloys, two ceramics, two iron oxides, and twenty-two elastomers in several combinations, temperature levels, and durations. Compatibility experiments of elastomers and non-elastomeric sealants in aqueous solutions and lubricating oils were performed. The development of the downwell packer necessitated the completion of an elastomer formulation development program. The system component material selection and specifications for the pump system are given. The seal material selection for the stand-alone turbine-pump-unit is presented in detail.

Effect of nitrogen fertilizer and nodulation on lime-induced chlorosis in soybeans
Previous studies have indicated that addition of nitrogen to Fe-inefficient PI54619-5-1 soybeans, when grown in calcareous Hacienda loam soil, intensified iron chlorosis. It was reasoned that when large amounts of nitrate were taken up, more hydroxyl ions were expelled by roots with resultant less availability of soil Fe. It was further reasoned that if N were fixed symbiotically, cation (K, Ca, Mg) uptake would considerably exceed anion (H/sub 2/PO/sup -//sub 4/, Cl/sup -/) uptake with no need for uptake of NO/sub 3//sup -/ with resultant increase in protons excreted. Iron availability then would be increased and there would be less Fe deficiency. An experiment was conducted with and without innoculation with the PI54619-5-1 soybeans in the calcareous soil to test the ability of nodules to prevent Fe chlorosis. The only plants in the experiment with nodules were those with innoculum added and these plants were most free of Fe chlorosis. Iron analyses indicated that the hypothesis may be correct. It can be concluded that cation-anion uptake balance has much to do with the onset of lime-induced chlorosis. The relative uptake of NH/sub 4//sup +/ and NO/sub 3//sup -/ species of nitrogen can be important considerations in the cation-anion balance.

PICLE: a 2-D code for laser-beam - gas-jet interaction studies
A heat transport hydrodynamic PIC code was adapted for application to the KMSF gas-jet experiments. The input material density profile was changed from the original solid slab geometry to a cylindrically symmetric profile modeling the gas-jet plume. The target material was changed from the original Z = 1 to arbitrary Z. Energy deposition was modified to include inverse bremsstrahlung and resonance absorption. Preliminary results indicate electron thermal conduction dominates over mass flow for times up to about the laser pulse length. Electron thermal conduction is seen to vary between classical and flux-limited values spatially and temporally according to plasma conditions. Applications of this code, entitled PICLE (Particle-In-Cell Laser Equipment code), to absorption and flux-limit parameter studies are described. A source listing and sample input deck are included.

Moment series for the coefficient of variation in Weibull sampling
For the 2-parameter Weibull distribution function F(t) = 1 - exp(-t/b)/sup c/, t > 0, with c and b positive, a moment estimator c* for c is the solution of the equationGAMMA(1 + 2/c*)/GAMMA/sup 2/ (1 + 1/c*) = 1 + v*/sup 2/ where v* is the coefficient of variation in the form ..sqrt..m/sub 2//m/sub 1/', m/sub 1/' being the sample mean, m/sub 2/ the sample second central moment (it is trivial in the present context to replace m/sub 2/ by the variance). One approach to the moments of c* (Bowman and Shenton, 1981) is to set-up moment series for the scale-free v*. The series are apparently divergent and summation algorithms are essential; we consider methods due to Levin (1973) and one, introduced ourselves (Bowman and Shenton, 1976).

Electron interactions with polar molecules
A description is given of a number of the features of discrete and continuous spectra of electrons interacting with polar molecules. Attention is focused on the extent to which theoretical predictions concerning cross sections, resonances, and bound states are strongly influenced by the various approximations that are so ubiquitous in the treatment of such problems. Similarly, threshold scattering and photodetachment processes are examined for the case of weakly bound dipole states whose higher members overlap the continuum.

Small-angle physics at ISABELLE
ISABELLE will be commissioned a few years after the anti p p colliders, whose plans and first results have been presented here. A look at the design goals for ISABELLE reveals that the two salient features offered in compensation for the later turn-on are high luminosity and (2 x 10/sup 5/-10/sup 6/mb/sup -1/sec/sup -1/) and the number of intersections available for physics. With expected Z/sup 0/ detection rates of in UA1, it is clear that all but the most rudimentary features of the standard picture will remain obscure until ISABELLE-like luminosity is available. Some nonstandard models will be hard to distinguish from the standard one until high statistics can be accumulated above the masses of the standard vector bosons. The availability of a relatively large number of intersections at ISABELLE means that there will be room for some highly specific setups which can capitalize on the high luminosity in high-precision or rare-process studies.
