in the data acquisition chamber. The various residual ion, neutral, and photon beams exit through
an aperture in the outer hemisphere of the analyzer and are detected by a Faraday cup detector. The
interaction region has magnetic field coils to null the earth's magnetic field throughout this region.
The predicted continuum state structure (energy locations, widths, and magnitudes) are very
sensitive to specific atomic structure theory approximations, and experimental measurements such
as the ones currently proposed will provide stringent tests of our understanding of the electronelectron
and electron-nucleus interactions that occur in atoms and ions.
