The Brookhaven Accelerator Test Facility (ATF) uses a photocathode rf gun to provide a high-brightness electron beam intended for FEL and laser acceleration experiments. The rf gun consists of 1-,' cells driven at 2856 MHz in 7r-mode with a maximum cathode field of 100 MV/m. To achieve long lifetimes, our photocathode development concentrates on robust(More)
We consider the potential for a free-gallium-jet as an option for the pion-production target at a Muon Collider or Neutrino Factory. Advantages of such a target choice are its liquid state at relatively low temperature, its relatively efficient meson production, and its lower activation (compared to mercury). Using the MARS15 code, we have simulated(More)

We propose to perform a proof-of-principle test of a target station suitable for a Neutrino Factory or Muon Collider source using a 24-GeV proton beam incident on a target consisting of a free mercury jet that is inside a 15-T capture solenoid magnet. This test could be performed in the TT2A tunnel of the nTOF proton line (upstream of the spallation(More)
2 Preface In response to the growing interest in building a Neutrino F actory 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(More)
The MERIT experiment, which ran at CERN in 2007, is a proof-of-principle test for a target system that converts a 4-MW proton beam into a high-intensity muon beam for either a neutrino factory complex or a muon collider. The target system is based on a free mercury jet that intercepts an intense proton beam inside a 15-T solenoidal magnetic field. Here, we(More)
The mercury jet target geometry. The proton beam and mercury jet cross at z=-37.5 cm. Figure 3: The layout of multiple proton beam entry directions relative to mercury jet at z=-75 cm. Abstract A study of a pion production and capture system for a 4 MW target station for a neutrino factory or muon collider is presented. Using the MARS code [1], we simulate(More)
The requirement for high luminosity in a + ? collider leads one to conclude that a prodigious source of pions is needed followed by an efficient capture/decay channel. Significant targetry issues are raised by these demands. Among these are i) the best target configuration to tolerate a high-rep rate, high-power proton beam (10 14 ppp at 15 Hz), ii) the(More)
