  Target protection is an important part of machine protection. The beam power
in high-intensity accelerators is high enough that a single wayward pulse can
cause serious damage. Today's high-power targets operate at the limit of
available technology, and are designed for a very narrow range of beam
parameters. If the beam pulse is too far off centre, or if the beam size is not
correct, or if the beam density is too high, the target can be seriously
damaged. We will start with a brief introduction to high-power targets and then
move to a discussion of what can go wrong, and what are the risks. Next we will
discuss how to control the beam-related risk, followed by examples from a few
different accelerator facilities. We will finish with a detailed example of the
Oak Ridge Spallation Neutron Source target tune up and target protection.
