• Energy deposition is calculated by FLUKA for the initial
state and then extrapolated to new density distributions.
• The peak temperature in the beam-heated region is in the
order of 10eV (100.000K) and the pressure is about
15GPa.
• A density depletion channel appears in the beam-heated
region and grows with time so later bunches penetrate
further into the material.
– Verify simulations (FLUKA-BIG-2[EOS])

Experiment• Cu or W target• ~200cm length (LHC-beam depletion front moves 0.35m/us) • 10-15cm radius• Multiple test points
– Calibration– Low intensity test– High intensity (full SPS-beam)
• Maybe, split into several sections• Enclosed by a shield
