A coplanar (e, 2e) spectrometer has been modified to make out-of-scattering plane measurements of ejected electron angular distributions. During an experiment, the electron detectors are fixed and the gun moves on the surface of a cone. This special geometry yields the full 360° (e, 2e) angular distribution of electrons ejected into a plane normal to the scattered electron direction. The modifications are compact and fit inside the existing vacuum chamber.
