Granular solid targets made of fluidized tungsten powder or static pebble bed of tungsten spheres, have been long proposed and are being studied as an alternative configurations towards high-power (>1MW of beam power) target systems, suitable for a future Super Beam or Neutrino Factory. Serving the lack of experimental data on this field, a feasibility experiment was performed in HiRadMat facility of CERN/SPS that tried in a pulse-by-pulse basis to address the effect of the impact of the SPS beam (440GeV/c) on a static tungsten powder target. Online instrumentation such as high-speed photography and Laser - Doppler Vibrometry was employed. Preliminary results show a powder disruption speed of less than 0.5 m/s while the disruption height appears to be scaling proportionally with the beam intensity. Other analysis results will be discussed. | ||
