Recent simulations of pressure waves inside Gallium and Mercury jets made by Ahmed Hassanein, ANL, (HEIGHTS code)
Cylindrical jet, radius 10 mm
Gaussian proton beam, 2 x 5 1013 protons, ?r=4 mm
Temperature rise along the jet axis for protons of 16 GeV/c is estimated to be be in the region of 300� C. Protons of 2 GeV/c (constant beam power) would raise the axial region to ~750� C, i.e. well above the boiling point of mercury (357� C)
The HEIGHTS code predicts that the jet will not break up when the beam passes - needs benchmarks.
