We report initial results of exposing low-Z solid and high-Z liquid targets to 150-ns, 4×1012 proton pulses with spot sizes on the order of 1 to 2 mm. The energy deposition density approached 100 J/g. Diagnostics included fiberoptic strain sensors on the solid target and high-speed photography of the liquid targets. This work is part of the R&D program of(More)

We describe the status of the effort to realize a first neutrino factory and the progress made in understanding the problems associated with the collection and cooling of muons towards that end. We summarize the physics that can be done with neutrino factories as well as with intense cold beams of muons. The physics potential of muon colliders is reviewed,(More)

We analyze the prospects of a feasible, Brookhaven National Laboratory based, very long baseline neutrino oscillation experiment consisting of a conventional horn produced low energy wideband beam and a detector of 500 kton fiducial mass with modest requirements on event recognition and resolution. Such an experiment is intended primarily to determine CP(More)
We describe measurements performed on samples consisting of the alloy Super-Invar, which is a candidate material for a robust solid target used in conjunction with an intense pulsed proton beam. A low coefficient of thermal expansion is the characteristic property which makes Superlnvar an attractive target candidate. We have irradiated our samples at the(More)
The international Muon Ionization Cooling Experiment (MICE), which is under construction at the Rutherford Appleton Laboratory (RAL), will demonstrate the principle of ionization cooling as a technique for the reduction of the phase-space volume occupied by a muon beam. Ionization cooling channels are required for the Neutrino Factory and the Muon Collider.(More)
In an effort to address the limitations on high-power accelerator target performance prompted by the elevated dose levels and the associated irradiation damage, an experimental study has been conducted to explore interesting new alloys and composites under the influence of protons and neutrons. Material irradiations were performed using the 200-MeV protons(More)
The requirement for high luminosity in a μ+μ− 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 ppp at 15 Hz), ii) the(More)
