Pacific Lamprey Research and Restoration : Annual Report 1996. (open access)

Pacific Lamprey Research and Restoration : Annual Report 1996.

The once abundant stocks of Pacific lamprey (Lampetra tridentata) above Bonneville Dam are currently depressed (Close et al. 1995). It is likely that many of the same factors that led to the decline of wild stocks of Columbia River Pacific salmon and steelhead have impacted Pacific lamprey populations. The Pacific lamprey is an important part of the food web of North Pacific ecosystems, both as predator and prey. Lamprey (a.k.a. eels) are also a valuable food and culture resource for American Indian Tribes of the Pacific Northwest. Depressed Pacific lamprey runs have impacted treaty secured fishing opportunities by forcing tribal members to gather this traditional food in lower Columbia River locations. The Pacific Lamprey Research and Restoration Project, funded by Bonneville Power Administration, is a cooperative effort between the Confederated Tribes of The Umatilla Indian Reservation, the Columbia River Intertribal Fish Commission, and Oregon State University with the goal to increase Pacific lamprey stocks above Bonneville Dam. The initial objectives of the project are to determine the past and current abundance of Pacific lamprey stocks in major mid Columbia tributaries and at various hydroelectric facilities, and to determine factors limiting Pacific lamprey abundance and distribution. Ultimately, Pacific lamprey restoration plans …

Luminosity Lifetime (open access)

Luminosity Lifetime

In a symmetric or 'energy transparent' relativistic collider, the luminosity is given by L = N{sup 2}f{sub c}/4{pi}{sigma}*{sub x}{sigma}*{sub y} where N is the number of electrons or positrons per bunch, {sigma}*{sub x} ({sigma}*{sub y}) is the horizontal (vertical) rms beam size at the interaction point (IP), and f{sub c} is the collision frequency. If the beam sizes remain constant as the luminosity decreases, then the time dependence of luminosity is contained entirely in the time dependence of the beam currents, i.e., N O N(t), and we can rewrite the equation as L(t) = N{sup 2}(t)f{sub c}/4{pi}{sigma}*{sub x}{sigma}*{sub y}. There are two distinct categories for luminosity loss. In the first category are loss processes due to collisions between the two beams, that is, processes associated directly with the luminosity. In the second category (see below) are single-beam loss processes. The processes in the first category relevant to a high-energy collider are Bhabha scattering (e{sup +}e{sup -} O e{sup +}e{sup -}) and 'radiative' Bhabha scattering (e{sup +}e{sup -} O e{sup +}e{sup -}{gamma}). In the first process, a beam particle is lost if its angular deflection is beyond the ring's transverse acceptance; in the second process, loss occurs if the beam particle's …

Monitoring and Evaluation of Smolt Migration in the Columbia River Basin, Volume IV : Evaluation of the 1998 Predictions of the Run-timing of Wild Migrant Yearling and Subyearling Chinook and Steelhead, and Hatchery Salmon in the Snake River Basin Using Program RealTime. (open access)

Monitoring and Evaluation of Smolt Migration in the Columbia River Basin, Volume IV : Evaluation of the 1998 Predictions of the Run-timing of Wild Migrant Yearling and Subyearling Chinook and Steelhead, and Hatchery Salmon in the Snake River Basin Using Program RealTime.

Program RealTime provided tracking and forecasting of the 1998 inseason outmigration via the internet for stocks of wild PIT-tagged spring/summer chinook. These stocks were from eight release sites above Lower Granite dam, including Bear Valley Creek, Catherine Creek, Elk Creek, Lake Creek, Imnaha River, Minam River, South Fork Salmon River, and Secesh River. Forecasts were also provided for a stock of hatchery-reared PIT-tagged summer-run sockeye from Redfish Lake and for the runs-at-large of Snake River wild yearling and subyearling chinook salmon, and steelhead. The 1998 Program RealTime performance was comparable to its performance in previous years for the whole-season evaluations for every stock tracked. Relative to 1997, performance improved for the yearling chinook run-at-large, and for predictions for last-half of the season for every other stock. Performance compared poorly with 1997 predictions for the first half of the runs of PIT-tagged yearling spring/summer chinook stocks and the run-at-large of fall subyearling chinook, and was slightly worse for the first half of the Redfish Lake sockeye run and the steelhead run-at-large. Poor first-half performance was likely due to the unusually large (and in some cases short) outmigrations in 1998. Utilization in 1998 of a different method of adjusting smolt counts at …

Design and Analysis of Salmonid Tagging Studies in the Columbia Basin. Volume III, Experiment Designs and Statistical Models to Estimate the Effect of Transportation on Survival of Columbia River System Salmonids. (open access)

Design and Analysis of Salmonid Tagging Studies in the Columbia Basin. Volume III, Experiment Designs and Statistical Models to Estimate the Effect of Transportation on Survival of Columbia River System Salmonids.

Experiment designs to estimate the effect of transportation on survival and return rates of Columbia River system salmonids are discussed along with statistical modeling techniques. Besides transportation, river flow and dam spill are necessary components in the design and analysis, otherwise questions as to the effects of reservoir drawdowns and increased dam spill may never be satisfactorily answered. Four criteria for comparing different experiment designs are: (1) feasibility; (2) clarity of results; (3) scope of inference; and (4) time to learn. A controlled experiment with treatments that are a combination of transport status (transported or left in-river), river flow level, and dam spill level should provide the clearest results of transport effect. The potential for bias due to interactions between year effects and the treatments is minimized by running as many treatments as possible within a single outmigration year. Relatedly, the most rapid learning will occur if several different treatments are implemented at randomly chosen time periods within thesame outmigration season. If the range of flow and dam manipulation includes scenarios of interest to managers, the scope of inference should be satisfactory. On the other hand these designs may be the least feasible; trying to manage the river system under …

Development of regenerable copper-based sorbents for hot gas cleanup: Final technical report, September 1, 1995--August 31, 1996 (open access)

Development of regenerable copper-based sorbents for hot gas cleanup: Final technical report, September 1, 1995--August 31, 1996

The overall objective of this study was to determine the effectiveness of the copper-chromite sorbent (developed in previous ICCI-funded projects) for longer duration application under optimum conditions in the temperature range of 550{degrees}-650{degrees}C to minimize sorbent reduction and degradation during the cyclic process. Three (3) formulations of attrition resistant granules of the copper chromite sorbent (i.e., CuCr-10, CuCr-21, and CuCr-29) as well as one (1) copper chromite sorbent in pellet form (i.e., CuCr-36) were selected for cyclic desulfurization tests. The desulfurization and regeneration capabilities of the selected formulations as well as the effects of operating parameters were determined, to identify the {open_quotes}best{close_quotes} sorbent formulation and the optimum operating conditions. The durability of the {open_quotes}best{close_quotes} sorbent formulation was determined in {open_quotes}long-term{close_quotes} multicycle tests conducted at the optimum operating conditions. The attrition resistance of the selected formulations were determined and compared with those of other sorbents, including a limestone, a dolomite, and a commercial zinc titanate sorbent. The results obtained in this study indicate that, the CuCr-29 sorbent has excellent attrition resistance and desulfurization performance, which are far superior to the commercial zinc titanate sorbents. The optimum desulfurization temperature in terms of sorbent efficiency and utilization appears to be about 600{degrees}C. Sorbent …

Monitored energy use of homes with geothermal heat pumps: A compilation and analysis of performance. Final report (open access)

Monitored energy use of homes with geothermal heat pumps: A compilation and analysis of performance. Final report

The performance of residential geothermal heat pumps (GHPs) was assessed by comparing heating, ventilation, and air conditioning (HVAC) system and whole house energy use of GHP houses and control houses. Actual energy savings were calculated and compared to expected savings (based on ARI ratings and literature) and predicted savings (based on coefficient of performance - COP - measurements). Differences between GHP and control houses were normalized for heating degree days and floor area or total insulation value. Predicted savings were consistently slightly below expected savings but within the range of performance cited by the industry. Average rated COP was 3.4. Average measured COP was 3.1. Actual savings were inconsistent and sometimes significantly below predicted savings. No correlation was found between actual savings and actual energy use. This suggests that factors such as insulation and occupant behavior probably have greater impact on energy use than type of HVAC equipment. There was also no clear correlation between climate and actual savings or between climate and actual energy use. There was a trend between GHP installation date and savings. Newer units appear to have lower savings than some of the older units which is opposite of what one would expect given the increase …

Operation of CEBAF With Heavy Beamloading (open access)

Operation of CEBAF With Heavy Beamloading

CEBAF is a 4 GeV, 200 {micro}A five-pass recirculating superconducting electron accelerator that has been operating for nuclear physics research at full energy since November 95. The beam current has been increased to over 180 {micro}A at 4 GeV with the maximum current in the linac over 900 {micro}A. The superconducting cavities operate in a regime where the beam-induced voltage is comparable to the accelerating gradient. The operational limits and the issues required to maintain stable operation of the 1,497 MHz superconducting cavities will be discussed, together with the implications for the other accelerator systems. There are three experimental Halls which can run simultaneously with three interleaved 499 MHz bunch trains and RF separators. Operation with simultaneous beams to two Halls is now routine, and simultaneous three beam operation has been demonstrated. The maximum design current per bunch train (120 {micro}A) has been achieved. Hall B eventually requires beam currents as low as 1 nA (200 pA has been delivered) simultaneous with delivery of up to 200 {micro}A to the other Halls. The required beam current ratio of 10,000 has been achieved; development of 1 nA beam position monitors continues.

Search for Anomalous WW/WZ {r_arrow} e{nu}jj Production at D0; Busqueda de Produccion Anomala WW/WZ {r_arrow}e{nu}jj en D-Zero

A search for anomalous WW and WZ production in p{anti p} collisions at {radical}s = 1.8 TeV using the D0 detector at Fermilab is presented. With a data sample of p{anti p} {r_arrow} e{nu}jjX events corresponding to an integrated luminosity of 76.5 {+-} 4.1pb{sup {minus}1}. 399 candidate events were identified, from which 387.1 {+-} 39.8 events were estimated to be background. No deviations from the Standard Model were seen, which predicts 16.2 {+-} 2.7 events. The 95% CL limit on the cross section {sigma}(p{anti p} {r_arrow} W{sup +}W{sup {minus}}X) was calculated to be 93.8 pb. Limits on the CP-conserving anomalous WW{sub {gamma}} and WWZ coupling parameters were obtained from a binned likelihood fit to the transverse momentum spectrum of the W boson. Assuming that the WW{sub {gamma}} and WWZ coupling parameters are equal, the 95% CL limits on the CP-conserving couplings are {minus}0.56 < {Delta}{kappa} < 0.75 (with {lambda} = 0) and {minus}0.42 < {lambda} < 0.44 (with {Delta}{kappa} = 0), for a form factor scale {Lambda}{sub FF} = 1.5 TeV.

Jefferson Lab Personnel Safety Fast Beam Kicker System (open access)

Jefferson Lab Personnel Safety Fast Beam Kicker System

The CEBAF accelerator at Thomas Jefferson National Accelerator Facility (Jefferson Lab) uses a continuous electron beam with up to 800 kilowatts of average beam power. The laboratory beam containment policy requires that in the event of an errant beam striking a beam blocking device, the beam must be shut off by three methods in less than 1 millisecond. One method implemented is to shut off the beam at the gun. Two additional methods have been developed which use fast beam kickers to deflect the injector beam on to a water cooled aperture. The kickers designed and implemented at Jefferson lab are able to deflect the injector beam in less than 200 microseconds. The kicker system includes self-test and monitoring capabilities that enable the system to be used for personnel safety.

Runtime Accelerator Configuration Tools at Jefferson Laboratory

RF and magnet system configuration and monitoring tools are being implemented at Jefferson Lab to improve system reliability and reduce operating costs. They are prototype components of the Momentum Management System being developed. The RF is of special interest because it affects the momentum and momentum spread of the beam, and because of the immediate financial benefit of managing the klystron DC supply power. The authors describe present and planned monitoring of accelerating system parameters, use of these data, RF system performance calculations, and procedures for magnet configuration for handling beam of any of five beam energies to any of three targets.

Automated Path Length and M{Sub 56} Measurements at Jefferson Lab (open access)

Automated Path Length and M{Sub 56} Measurements at Jefferson Lab

Accurate measurement of path length and path length changes versus momentum (M{sub 56}) are critical for maintaining minimum beam energy spread in the CEBAF (Continuous Electron Beam Accelerator Facility) accelerator at the Thomas Jefferson National Accelerator Facility (Jefferson Lab). The relative path length for each circuit of the beam (1256m) must be equal within 1.5 degrees of 1497 MHz RF phase. A relative path length measurement is made by measuring the relative phases of RF signals from a cavity that is separately excited for each pass of a 4.2 {mu}s pulsed beam. This method distinguishes the path length to less than 0.5 path length error. The development of a VME based automated measurement system for path length and M{sub 56} has contributed to faster machine setup time and has the potential for use as a feedback parameter for automated control.

Over-the-road shock and vibration testing of the radioisotope thermoelectric generator transportation system (open access)

Over-the-road shock and vibration testing of the radioisotope thermoelectric generator transportation system

Radioisotope Thermoelectric Generators (RTG) convert heat generated by radioactive decay into electricity through the use of thermocouples. The RTGs have a long operating life, are reasonably lightweight, and require little or no maintenance, which make them particularly attractive for use in spacecraft. However, because RTGs contain significant quantities of radioactive materials, normally plutonium-238 and its decay products, they must be transported in packages built in accordance with Title 10, Code of Federal Regulations, Part 71 (10 CFR 71). To meet these regulations, a RTG Transportation System (RTGTS) that fully complies with 10 CFR 71 has been developed, which protects RTGs from adverse environmental conditions during normal conditions of transport (e.g., shock, vibration, and heat). To ensure the protection of RTGs from shock and vibration loadings during transport, extensive over-the-road testing was conducted on the RTG`S to obtain real-time recordings of accelerations of the air-ride suspension system trailer floor, packaging, and support structure. This paper provides an overview of the RTG`S, a discussion of the shock and vibration testing, and a comparison of the test results to the specified shock response spectra and power spectral density acceleration criteria.

A Next-to-Leading-Order QCD Analysis of Neutrino-Iron Structure Functions at the Tevatron

Nucleon structure functions measured in neutrino-iron and antineutrino-iron charged-current interactions are presented. The data were taken in two high-energy high-statistics runs by the LAB-E detector at the Fermilab Tevatron. Structure functions are extracted from a sample of 950,000 neutrino and 170,000 antineutrino events with neutrino energies from 30 to 360 GeV. The structure functions F{sub 2} and xF{sub 3} are compared with the predictions of perturbative Quantum Chromodynamics (PQCD). The combined non-singlet and singlet evolution in the context of PQCD gives value of {Lambda}NLO,(4)/MS = 337 {+-} 28 (exp.)
