  We perform the first experimental study with full detector simulation for the
radiative production of neutralinos at the linear collider, at sqrt{s} = 500
GeV and realistic beam polarizations. We consider all relevant backgrounds,
like the Standard Model background from radiative neutrino production. The
longitudinal polarized beams enhance the signal and simultaneously reduce the
background, such that statistical errors are significantly reduced. We find
that the photon spectrum from the signal process can be well isolated. The
neutralino mass and the cross section can be measured at a few per-cent level,
with the largest systematic uncertainties from the measurement of the beam
polarization and the beam energy spectrum.
