The Spallation Neutron Source now being built in Oak Ridge, Tennessee,
USA, accelerates an H- ion beam to 1000 MeV with an average power of 1.4
MW. The H- beam is then stripped to H+, compressed in a storage ring to a
pulse length of 695 ns, and then directed onto a mercury neutron
spallation target. Most of the acceleration is accomplished with
superconducting rf cavities. The presence of these cavities, the high
average beam power, and the large range of beam intensity in the storage
ring, provide unique challenges to the beam diagnostics systems. In this
talk we will discuss these challenges and some of our solutions,
including the laser profile monitor system, the residual gas ionization
profile monitors, and network attached devices. Measurements performed
using prototype instrumentation will also be presented.
