Article de conférence

Granular solid targets made of fluidized tungsten powder or a static pebble bed of tungsten spheres, have been proposed and are being studied as an alternative configuration for high-power (>1MW of beam power) target systems, suitable for a future Super Beam or Neutrino Factory. Due to the lack of experimental data on this field, a feasibility experiment was performed in HiRadMat facility of CERN to address the effect of the impact of the SPS beam (440 GeV/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 0.6 m/s at 3 1011 protons/pulse while the disruption speed appears to scale with the beam intensity.

Feasibility Experiment of a Granular Target for Future Neutrino Facilities

Nikolaos Charitonidis, Leonid Rivkin

Granular, solid targets made of fluidized tungsten powder or static pebble bed of tungsten spheres, have been 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. With the lack of experimental data on this field, a feasibility experiment was performed in HiRadMat facility of CERN/SPS that tried on a pulse-by-pulse basis to address the effect of the impact of the SPS beam (440GeV/c) on a static tungsten granular target. Online instrumentation such as high-speed photography and laser-Doppler vibrometry was employed. Preliminary results show a powder disruption speed of less than 0.6 m/s at 3E11 protons/pulse while the disruption speed appears to be scaling proportionally with the beam intensity.

Feasibility Experiment Of Granular Target Options for Future Neutrino Facilities

Nikolaos Charitonidis, Leonid Rivkin

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.

Radiological assessment of the Tungsten Powder Test (HRM10) at HiRadMat

Nikolaos Charitonidis

Granular solid targets made of fluidised tungsten powder have been long proposed and are being studied as an alternative configuration towards high-power (>1MW beam power) target systems, suitable for a future Super Beam facility or Neutrino Factory. A feasibility experiment to evaluate this kind of target is being prepared to be performed at HiRadMat facility of CERN/SPS. Activation studies in order to assess the radiological risk from this experiment have been carried out, in order to estimate the necessary cooling time to access and handle the experimental equipment, and for defining the specialized laboratory class for the post-mortem examination of the sample.
