Feasibility Experiment Of Granular Target Options for Future Neutrino Facilities

Fragmented solid targets made of either fluidised tungsten powder or static pebble bed of tungsten spheres, have been long proposed and are being studied as an alternative configuration towards high-power (>1 MW of beam power) target systems, suitable for a future Super Beam or Neutrino Factory. Such assemblies offer many advantages as better thermal and inertial stress absorption, thermal cooling and, if in the fluidised form, regeneration. We propose to perform a validation test of a tungsten powder target. The proposed feasibility experiment will try on a pulse-by-pulse basis to address the effect of the impact of a high-power pulsed beam in such an assembly using both online diagnostic tools with high-speed cameras, laser vibrometry and acoustic measurements, as well as offline, post-irradiation analysis of the target material.
