Using the Fermilab Proton Source for a Muon to Electron Conversion Experiment
The Fermilab proton source is capable of providing 8 GeV protons for both the
future long-baseline neutrino program (NuMI), and for a new program of low
energy muon experiments. In particular, if the 8 GeV protons are rebunched and
then slowly extracted into an external beamline, the resulting proton beam
would be suitable for a muon-to-electron conversion experiment designed to
improve on the existing sensitivity by three orders of magnitude. We describe a
scheme for the required beam manipulations. The scheme uses the Accumulator for
momentum stacking, and the Debuncher for bunching and slow extraction. This
would permit simultaneous operation of the muon program with the future NuMI
program, delivering 10^20 protons per year at 8 GeV for the muon program at the
cost of a modest (~10%) reduction in the protons available to the neutrino
program.Comment: 18 pages, 7 figure
Operation and performance of the new Fermilab Booster H- injection system
The operation and performance of the new, 15 Hz, H{sup -} charge exchange injection system for the FNAL Booster is described. The new system installed in 2006 was necessary to allow injection into the Booster at up to 15 Hz. It was built using radiation hardened materials which will allow the Booster to reliably meet the high intensity and repetition rate requirements of the Fermilab's HEP program. The new design uses three orbit bump magnets (Orbumps) rather than the usual four and permits injection into the Booster without a septum magnet. Injection beam line modification and compensation for the quadrupole gradients of the Orbump magnets is discussed

Preparations for Muon Experiments at Fermilab
The use of existing Fermilab facilities to provide beams for two muon experiments--the Muon to Electron Conversion Experiment (Mu2e) and the New g-2 Experiment--is under consideration. Plans are being pursued to perform these experiments following the completion of the Tevatron Collider Run II, utilizing the beam lines and storage rings used today for antiproton accumulation without considerable reconfiguration

New corrector system for the Fermilab booster
We present an ambitious ongoing project to build and install a new corrector system in the Fermilab 8 GeV Booster. The system consists of 48 corrector packages, each containing horizontal and vertical dipoles, normal and skew quadrupoles, and normal and skew sextupoles. Space limitations in the machine have motivated a unique design, which utilizes custom wound coils around a 12 pole laminated core. Each of the 288 discrete multipole elements in the system will have a dedicated power supply, the output current of which is controlled by an individual programmable ramp. This paper describes the physics considerations which drove the design, as well as issues in the control of the system
Physics at a Neutrino Factory
In response to the growing interest in building a Neutrino Factory to produce
high intensity beams of electron- and muon-neutrinos and antineutrinos, in
October 1999 the Fermilab Directorate initiated two six-month studies. The
first study, organized by N. Holtkamp and D. Finley, was to investigate the
technical feasibility of an intense neutrino source based on a muon storage
ring. This design study has produced a report in which the basic conclusion is
that a Neutrino Factory is technically feasible, although it requires an
aggressive R&D program. The second study, which is the subject of this report,
was to explore the physics potential of a Neutrino Factory as a function of the
muon beam energy and intensity, and for oscillation physics, the potential as a
function of baseline.Comment: 133 pages, 64 figures. Report to the Fermilab Directorate. Available
