2 MW upgrade of the Fermilab Main Injector (open access)

2 MW upgrade of the Fermilab Main Injector

In January 2002, the Fermilab Director initiated a design study for a high average power, modest energy proton facility. An intensity upgrade to Fermilab's 120-GeV Main Injector (MI) represents an attractive concept for such a facility, which would leverage existing beam lines and experimental areas and would greatly enhance physics opportunities at Fermilab and in the U.S. With a Proton Driver replacing the present Booster, the beam intensity of the MI is expected to be increased by a factor of five. Accompanied by a shorter cycle, the beam power would reach 2 MW. This would make the MI a more powerful machine than the SNS or the J-PARC. Moreover, the high beam energy (120 GeV) and tunable energy range (8-120 GeV) would make it a unique high power proton facility. The upgrade study has been completed and published. This paper gives a summary report.

An 8-GeV Synchrotron-Based Proton Driver (open access)

An 8-GeV Synchrotron-Based Proton Driver

In January 2002, the Fermilab Director initiated a design study for a high average power, modest energy proton facility. Such a facility is a possible candidate for a construction project in the U.S. starting in the middle of this decade. The key technical element is a new machine, dubbed the ''Proton Driver,'' as a replacement of the present Booster. The study of an 8-GeV synchrotron-based proton driver has been completed and published. This paper will give a summary report, including machine layout and performance, optics, beam dynamics issues, technical systems design, civil construction, cost estimate and schedule.

Analysis of Materials in an Experimental Testing Pipe System for an Inhibitor of Mussel Kill (open access)

Analysis of Materials in an Experimental Testing Pipe System for an Inhibitor of Mussel Kill

A comprehensive series of 16 laboratory experiments demonstrated that the presence of vinyl tubing within a recirculating pipe system was responsible for lowering zebra mussel kill following treatment with the bacterium Pseudomonas fluorescens. All vinyl tubing was replaced in all testing units with silicone tubing, and high mussel kill (>95%) was then obtained.

B physics at CDF (open access)

B physics at CDF

B physics is at the core of the CDF agenda for Run II. With the Tevatron performance gradually improving, samples of data corresponding to about 70 pb{sup -1} are now available. Due to improved detector capabilities these data already allow one to improve a number of Run I results, as well as perform a series of new measurements. We present an overview of the current state of B physics at CDF.

Barrier RF stacking at Fermilab (open access)

Barrier RF stacking at Fermilab

A key issue to upgrade the luminosity of the Tevatron Run2 program and to meet the neutrino requirement of the NuMI experiment at Fermilab is to increase the proton intensity on the target. This paper introduces a new scheme to double the number of protons from the Main Injector (MI) to the pbar production target (Run2) and to the pion production target (NuMI). It is based on the fact that the MI momentum acceptance is about a factor of four larger than the momentum spread of the Booster beam. Two RF barriers--one fixed, another moving--are employed to confine the proton beam. The Booster beams are injected off-momentum into the MI and are continuously reflected and compressed by the two barriers. Calculations and simulations show that this scheme could work provided that the Booster beam momentum spread can be kept under control. Compared with slip stacking, a main advantage of this new method is small beam loading effect thanks to the low peak beam current. The RF barriers can be generated by an inductive device, which uses nanocrystal magnet alloy (Finemet) cores and fast high voltage MOSFET switches. This device has been designed and fabricated by a Fermilab-KEK-Caltech team. The first …

Bonneville Power Administration: Obligations to Fish and Wildlife in the Pacific Northwest (open access)

Bonneville Power Administration: Obligations to Fish and Wildlife in the Pacific Northwest

Testimony issued by the General Accounting Office with an abstract that begins "The Bonneville Power Administration produces a large portion of the Pacific Northwest's electric power, largely from hydroelectric projects in the Federal Columbia River Power System. Bonneville also has obligations to protect, mitigate, and enhance fish and wildlife populations affected by these hydroelectric projects. In the past several years, Bonneville has experienced financial difficulties, in part because of rising costs of providing power, lower-than-projected revenue from selling surplus power, and drought conditions. Bonneville's financial situation may adversely affect fish and wildlife. Stakeholders have expressed concern that Bonneville has effectively reduced spending on fish and wildlife programs. This testimony addresses (1) Bonneville's statutory and other obligations to support fish and wildlife programs, (2) Bonneville's historical spending and other efforts in support of fish and wildlife, (3) Bonneville's current financial condition, (4) Bonneville's recent actions that affect fish and wildlife programs, and (5) challenges Bonneville faces in supplying electricity to the region while simultaneously protecting, mitigating and enhancing fish and wildlife."

The BTeV pixel and microstrip detector (open access)

The BTeV pixel and microstrip detector

The BTeV pixel detector is one of the most crucial elements in the BTeV experiment. While the pixel detector is technically challenging, we have made great progress towards identifying viable solutions for individual components of the system. The forward silicon tracker is based on more mature technology and its design has benefited from the experience of other experiments. Nevertheless, we have started an R&D program on the forward silicon tracker and first results are expected some time next year.

Capitol Hill Anthrax Incident: EPA's Cleanup Was Successful; Opportunities Exist to Enhance Contract Oversight (open access)

Capitol Hill Anthrax Incident: EPA's Cleanup Was Successful; Opportunities Exist to Enhance Contract Oversight

A letter report issued by the General Accounting Office with an abstract that begins "In September and October 2001, the first cases of anthrax bioterrorism occurred in the United States when letters containing anthrax were mailed to congressional leaders and members of the news media. As the cleanup of the Capitol Hill anthrax site progressed, EPA's estimates of the cleanup costs steadily rose. GAO was asked to describe (1) the costs EPA incurred to conduct the cleanup and how it was funded, (2) the extent to which EPA awarded the cleanup contracts competitively, (3) EPA's oversight of the contractors' work and any suggested changes to EPA's contracting practices, and (4) the extent to which EPA agreed to indemnify contractors against liability for potential damages related to the cleanup."

Charm physics at the Tevatron (open access)

Charm physics at the Tevatron

The cross section of p{bar p} into charm is very high compared to e{sup +}e{sup -}-machines, but it is orders of magnitude smaller than the total cross section of {approx} 100mb. This explains the need for a good trigger mechanism. Traditionally charm physics at hadron colliders relies on a lepton signature. For example, the decay of the J{psi} into two leptons or semi-leptonic decays of D-mesons. Both detectors at the Tevatron, CDF and D0 have undergone substantial upgrades for RUN II. CDF now exploits a new trigger technique selecting more abundant hadronic decays. First charm physics results from the CDF and D0 experiments at the Tevatron Run II are presented. With the addition of the Secondary Vertex Trigger CDF has become a competitive charm experiment.

Chemical Weapons Convention: Issues for Congress (open access)

Chemical Weapons Convention: Issues for Congress

The CWC bans the development, production, stockpiling, and use of chemical weapons by members signatories. It also requires the destruction of all chemical weapons stockpiles and production facilities. Neither the United States nor Russia will be able to meet the original CWC’s deadlines for destruction of their CW stockpiles, and have been granted extensions to at least 2012. The Convention provides the most extensive and intrusive verification regime of any arms control treaty, extending its coverage to not only governmental but also civilian facilities. The Convention also requires export controls and reporting requirements on chemicals that can be used as warfare agents and their precursors. The CWC establishes the Organization for the Prohibition of Chemical Weapons (OPCW) to oversee the Convention’s implementation.

Fermilab booster modeling and space charge study (open access)

Fermilab booster modeling and space charge study

The Fermilab Booster is a bottleneck limiting the proton beam intensity in the accelerator complex. A study group has been formed in order to have a better understanding of this old machine and seek possible improvements. The work includes lattice modeling, numerical simulations, bench measurements and beam studies. Based on newly obtained information, it has been found that the machine acceptance is severely compromised by the orbit bump and dogleg magnets. This, accompanied by emittance dilution from space charge at injection, is a major cause of the large beam loss at the early stage of the cycle. Measures to tackle this problem are being pursued.

Fermilab recycler stochastic cooling commissioning and performance (open access)

Fermilab recycler stochastic cooling commissioning and performance

The Fermilab Recycler is a fixed 8 GeV kinetic energy storage ring located in the Fermilab Main Injector tunnel near the ceiling. The Recycler has two roles in Run II. First, to store antiprotons from the Fermilab Antiproton Accumulator so that the antiproton production rate is no longer compromised by large numbers of antiprotons stored in the Accumulator. Second, to receive antiprotons from the Fermilab Tevatron at the end of luminosity periods. To perform each of these roles, stochastic cooling in the Recycler is needed to preserve and cool antiprotons in preparation for transfer to the Tevatron. The commissioning and performance of the Recycler stochastic cooling systems will be reviewed.
