Abstract
Significant interest has recently focused on the use
of liquid-metal targets flowing with high velocities for
various high-power nuclear and high-energy physics applications
such as fusion reactor first-walls, the Spallation Neutron
Source, Isotope Separation On Line, and Muon Collider projects.
This is because the heat generated in solid targets due
to beam or plasma bombardment cannot be removed easily
and the resulting thermal shock damage could be a serious
lifetime problem for long-term operation. More recently,
the use of free or open flying-liquid jets has been proposed
for higher-power-density applications. The behavior of
a free-moving liquid mercury or gallium jet subjected to
proton beam deposition in a strong magnetic field has been
modeled and analyzed for the Muon Collider project. Free-liquid-metal
jets can offer significant advantages over conventional
solid targets, particularly for the more demanding and
challenging high-power applications. However, the use of
free-moving liquid-metal targets raises a number of new
and challenging problems such as instabilities of the jet
in a strong magnetic field, induced eddy-current effects
on jet shape, thermal-shock formation, and possible jet
fragmentation. Problems associated with shock heating of
liquid jets in a strong magnetic field are analyzed in
this study.
