Target Studies with BNL E951 at the AGS
We report initial results of exposing low-Z solid and high-Z liquid targets to 150-ns, 4 x 10{sup 12} 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 and D program of the Neutrino Factory and Muon Collider Collaboration

The R and D Program for Targetry at a Neutrino Factory
The need for intense muon beams for muon colliders [1] and for neutrino factories based on muon storage rings [2,3,4] leads to a concept of 1-4 MW proton beams incident a moving target that is inside a 20-T solenoid magnet, with a mercury jet as a preferred example. Novel technical issues for such a system include disruption of the mercury jet by the proton beam and distortion of the jet on entering the solenoid, as well as more conventional issues of materials lifetime and handling of activated materials in an intense radiation environment. As part of the R and D program [5] of the Neutrino Factory and Muon Collider Collaboration, R and D effort related to targetry is being performed within the context of BNL E951 [6], first results of which are discussed here and in other contributions to this conference
