Beryllium is a material extensively used in various particle accelerator beam lines and target facilities, as beam windows and, to a lesser extent, as secondary particle production targets. With increasing beam intensities of future multimegawatt accelerator facilities, these components will have to withstand even greater thermal and mechanical loads during operation. [...]

Observed proton beam induced disruption of a tungsten powder sample at CERN

Fluidized tungsten powder has been proposed as a potential target technology for particle accelerator applications with very high power highly focused pulsed beams. This has motivated a series of experiments carried out at the HiRadMat facility at CERN to study the response of a tungsten powder sample to an impinging high energy proton beam pulse. [...]

This paper reports the results from single-pulse experiments of a 440 GeV/$c$ proton beam interacting with granular tungsten samples in both vacuum and helium environments. Remote high-speed photography and laser Doppler vibrometry were used to observe the effect of the beam on the sample grains. [...]

Examination of Beryllium Under Intense High Energy Proton Beam at CERN's HiRadMat Facility

Beryllium is extensively used in various accelerator beam lines and target facilities as material for beam win- dows, and to a lesser extent, as secondary particle produc- tion targets. With increasing beam intensities of future ac- celerator facilities, it is critical to understand the response of beryllium under extreme conditions to avoid compro- mising particle production efficiency by limiting beam pa- rameters.

Neutrino Factory

The properties of the neutrino provide a unique window on physics beyond that described by the standard model. The study of subleading effects in neutrino oscillations, and the race to discover CP-invariance violation in the lepton sector, has begun with the recent discovery that $\theta_{13} > 0$. [...]

A Feasibility Experiment of a W-powder Target in the HiRadMat Facility of CERN

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.
