Analytical study and tracking simulations of the beam-beam compensation at Tevatron (open access)

Analytical study and tracking simulations of the beam-beam compensation at Tevatron

Head-on and long-range induced tunespread of about 0.025 in the Tevatron collider at Run II (together with the increased strength of the resonances) can significantly deteriorate the {bar p} lifetime and the collider luminosity. It was proposed to employ the so-called Tevatron Electron Lenses (TEL) to compress the beam-beam footprint and eliminate completely the bunch-to-bunch tunespread (PACMAN effect) for small amplitude particles. The first lens has been recently installed and tested [1]. This report presents results of analytical studies and tracking simulations of the linear beam-beam compensation (elimination of the bunch-to-bunch tune variation). Compression of the beam-beam footprint (nonlinear compensation) is discussed in [2].

Beam-beam interactions at the Tevatron in Run IIa (open access)

Beam-beam interactions at the Tevatron in Run IIa

The Tevatron in Run IIa will operate with three trains of twelve bunches each. The impact of the long-range interactions on beam stability will be more significant compared to Run I. We study these beam-beam interactions (head-on and long-range) with particle tracking using two different codes. The model includes machine nonlinearities such as the field errors of the Interaction Region quadrupoles and the chromaticity sextupoles. Tune footprints and dynamic apertures are calculated for different bunches in a train.

Benefits of Qualitative Simulation for Managing Fluctuating Staffing Needs (open access)

Benefits of Qualitative Simulation for Managing Fluctuating Staffing Needs

Management of the High Level Waste Program Office at the Idaho National Environmental and Engineering Laboratory has projected oscillating future employment levels. A simple computer model was created to help convince management that qualitative modeling of ''soft'' variables can provide appreciable insight into the consequences and performance of alternative staffing policies. Advocacy of the model underlying the simulation or a particular strategy did not motivate the study, but rather a desire to instill enthusiasm and elicit new and improved conceptual models from management. Six qualitative and three quantitative generic insights to managing staffing levels are gained from the simulations. These insights in their generic form should be familiar to those knowledgeable of system dynamics or computer/instrument process control. Their potential usefulness to developing staffing strategies is stressed. The two primary overarching assertions that flow from the simulation results are: (1) the presence of multiple feedbacks, time delays, and continuous flows introduce instability into a personnel system that complicates the management of staffing levels. Many times ''soft'' variables, such as morale, productivity, and efficiency are the sources of such influences; and (2) such influences can be successfully modeled. In the case of the simple model used in these simulations, for example, …

Concept of Operation for Waste Transport, Emplacement, and Retrieval (open access)

Concept of Operation for Waste Transport, Emplacement, and Retrieval

The preparation of this technical report has two objectives. The first objective is to discuss the base case concepts of waste transport, emplacement, and retrieval operations and evaluate these operations relative to a lower-temperature repository design. Aspects of the operations involved in waste transport, emplacement and retrieval may be affected by the lower-temperature operating schemes. This report evaluates the effects the lower-temperature alternatives may have on the operational concepts involved in emplacing and retrieving waste. The second objective is to provide backup material for the design description, in a traceable and defensible format, for Section 2 of the Waste Emplacement/Retrieval System Description Document.

Distribution of absorbed doses in the materials irradiated by ''RHODOTRON'' electron accelerator: Experiment and Monte Carlo simulations (open access)

Distribution of absorbed doses in the materials irradiated by ''RHODOTRON'' electron accelerator: Experiment and Monte Carlo simulations

This paper describes the experimental setup and presents studies of absorbed doses in different metals and dielectrics along with corresponding Monte Carlo energy deposition simulations. Experiments were conducted using a 5 MeV electron accelerator. We used several Monte Carlo code systems, namely MARS, MCNP, and GEANT to simulate the absorbed doses under the same conditions as in experiment. We compare calculated and measured high and low absorbed doses (from few kGy to hundreds kGy) and discuss the applicability of these computer codes for applied accelerator dosimetry.

Environmental impacts of options for disposal of depleted uranium tetrafluoride (UF{sub 4}). (open access)

Environmental impacts of options for disposal of depleted uranium tetrafluoride (UF{sub 4}).

The U.S. Department of Energy (DOE) evaluated options for managing its depleted uranium hexafluoride (UF{sub 6}) inventory in the Programmatic Environmental Impact Statement for the Long-Term Management and Use of Depleted Uranium Hexafluoride (PEIS) of April 1999. Along with the impacts from other management options, the PEIS discussed the environmental impacts from the disposal of depleted uranium oxide, which could result from the chemical conversion of depleted UF{sub 6}. It has been suggested that the depleted UF{sub 6} could also be converted to uranium tetrafluoride (UF{sub 4}) and disposed of. This report considers the potential environmental impacts from the disposal of DOE's depleted UF{sub 6} inventory after its conversion to UF{sub 4}. The impacts were evaluated for the same three disposal facility options that were considered in the PEIS for uranium oxide: shallow earthen structures, belowground vaults, and mines. They were evaluated for a dry environmental setting representative of the western United States. To facilitate comparisons and future decision making, the depleted UF{sub 4} disposal analyses performed and the results presented in this report are at the same level of detail as that in the PEIS.

Equilibration of Leachants with Basalt Rock for Repository Simulation Tests (open access)

Equilibration of Leachants with Basalt Rock for Repository Simulation Tests

In a nuclear waste repository in basalt, the groundwater will have a low redox potential (Eh) which may affect the leach rate of SRP waste glass. Accurate laboratory simulations of conditions in a basalt reposition must maintain low Eh values throughout the course of the experiment. In this report, important parameters affecting the ability of basalt to maintain appropriate Eh-pH conditions are examined, in particular basalt type and groundwater simulation.

Field Operations Program - Neighborhood Electric Vehicle Fleet Use (open access)

Field Operations Program - Neighborhood Electric Vehicle Fleet Use

This report summarizes a study of 15 automotive fleets that operate neighborhood electric vehicles (NEVs) in the United States. The information was obtained to help Field Operations Program personnel understand how NEVs are being used, how many miles they are being driven, and if they are being used to replace other types of fleet vehicles or as additions to fleets. (The Field Operations Program is a U.S. Department of Energy Program within the DOE Office of Energy Efficiency and Renewable Energy, Transportation Technologies). The NEVs contribution to petroleum avoidance and cleaner air can be estimated based on the miles driven and by assuming gasoline use and air emissions values for the vehicles being replaced. Gasoline and emissions data for a Honda Civic are used as the Civic has the best fuel use for a gasoline-powered vehicle and very clean emissions. Based on these conservation assumptions, the 348 NEVs are being driven a total of about 1.2 million miles per year. This equates to an average of 3,409 miles per NEV annually or 9 miles per day. It is estimated that 29,195 gallons of petroleum use is avoided annually by the 348 NEVs. This equates to 87 gallons of petroleum use …

FTS 2001 Implementation Issues (open access)

FTS 2001 Implementation Issues

Correspondence issued by the General Accounting Office with an abstract that begins "The General Services Administration (GSA) awarded FTS2001 contracts to Sprint and MCI Worldcom to provide long distance telecommunications services to federal agencies. The federal government began the sizable and complex effort of switching from the existing FTS 2000 contracts to FTS2001 in June 1999. Several implementation issues have delayed this transition. One of these issues concerns the billing problems experienced by GSA and its contractors. GAO found that the billing problems often arose from changes in contracts and services. According GSA, these issues also arose from the differences between contractors' commercial billing practices and the government's practices. Because these billing problems were not promptly resolved, they had an adverse effect on the transition progress. GSA is taking steps to resolve current billing problems. It is tracking issues as they arise, and it is now trying to resolve 12 issues still outstanding with Sprint and MCI WorldCom, including the problem of commercial billing. In addition, GSA's Office of Inspector General recently began a review of the FTS2001 billing area, which might also identify ways to prevent future billing problems. Another issue that affected the transition progress concerns the databases …

GEANT4 simulation and theoretical studies of a helical cooling channel (open access)

GEANT4 simulation and theoretical studies of a helical cooling channel

We present a conceptual design and detailed GEANT4 simulation of a helical ionization cooling channel proposed by Ya. Derbenev, which is able to cool in 3 dimensions (3-D). The lattice of the channel consists of a long solenoid (B=5 T, L=72 m, R=70 cm) and a transverse dipole magnetic field which rotates with a period of 1.8 m and an amplitude of 0.3 T. The cooling is achieved using lithium hydride wedge absorbers. Re-acceleration is performed by 201.25 MHz RF cavities which provide a 6.2 MeV per cooling cell. The parameters of the muon beam at the end of the channel are: transmission 85%, transverse and longitudinal emittances 0.6 cm and 2 cm, respectively.

ITS Technologies in Military Wheeled Tactical Vehicles: Status Quo and the Future

The U.S. Army operates and maintains the largest trucking fleet in the United States. Its fleet consists of over 246,000 trucks, and it is responsible for buying and developing trucks for all branches of the armed forces. The Army's tactical wheeled vehicle fleet is the logistical backbone of the Army, and annually, the fleet logs about 823 million miles. The fleet consists of a number of types of vehicles. They include eight different families of trucks from the High Mobility Multi-Purpose Wheeled Vehicles to M900 series line haul tractors and special bodies. The average age of all the trucks within the Army fleet is 15 years, and very few have more than traditional driving instrumentation on-board. Over the past decade, the Department of Transportation's (DOT's) Intelligent Transportation Systems (ITS) Program has conducted research and deployment activities in a number of areas including in-vehicle systems, communication and telematics technologies. Many current model passenger vehicles have demonstrated the assimilation of these technologies to enhance safety and trip quality. Commercial vehicles are also demonstrating many new electronic devices that are assisting in making them safer and more efficient. Moreover, a plethora of new technologies are about to be introduced to drivers that promise …

Low-budget muon source (open access)

Low-budget muon source

Generation of muon beams with protons on a current-carrying target followed by a lithium lens and a quadrupole decay channel is considered. A 8 GeV proton beam from the Fermilab Booster is used to provide a muon beam for the MUCOOL experiment for ionization cooling demonstration. The proposed scheme can also be used to create muon beams with a fraction of a 1 GeV proton beam of the Spallation Neutron Source. Monte Carlo simulations of the entire system are performed. For both cases optimization of the target and matching lithium lens is done. It is shown that such a set followed by an inexpensive decay channel based on quadrupole magnets with and without RF cavities provides a rather intense bunched muon beam.

Low energy improvements to the Fermilab 400-MeV linear accelerator (open access)

Low energy improvements to the Fermilab 400-MeV linear accelerator

Improvements in the Fermilab operating 400-MeV linear accelerator injector are required to achieve the beam intensity and emittance requirement of the Proton Driver design study [5]. It has been determined that these requirements can be achieved by replacing the components in the Linac below 10 MeV. An improved H{sup {minus}} ion source with an electrostatic transport to a two-section Radio-Frequency Quadrupole (RFQ) accelerator, with the RFQ sections separated by a magnetic five-dimensional phase-space imaging system as used in an earlier Fermilab/SAIC PET Project, and a new 10-MeV drift-tube linac cavity have been studied. It appears possible that an H{sup {minus}} intensity of 4.5 x 10{sup 13} ions per pulse with an improvement in beam emittance from the present system can be achieved with the proposed changes.

Magnetically levitated space elevator to low-earth orbit. (open access)

Magnetically levitated space elevator to low-earth orbit.

The properties of currently available NbTi superconductor and carbon-fiber structural materials enable the possibility of constructing a magnetically levitated space elevator from the earth's surface up to an altitude of {approx} 200 km. The magnetic part of the elevator consists of a long loop of current-carrying NbTi, composed of one length that is attached to the earth's surface in an east-west direction and a levitated-arch portion. The critical current density of NbTi is sufficiently high that these conductors will stably levitate in the earth's magnetic field. The magnetic self-field from the loop increases the levitational force and for some geometries assists levitational stability. The 200-km maximum height of the levitated arch is limited by the allowable stresses of the structural material. The loop is cryogenically cooled with helium, and the system utilizes intermediate pumping and cooling stations along both the ground and the levitated portion of the loop, similar to other large terrestrial cryogenic systems. Mechanically suspended from the basic loop is an elevator structure, upon which mass can be moved between the earth's surface and the top of the loop by a linear electric motor or other mechanical or electrical means. At the top of the loop, vehicles may …
