A double-focusing mass spectrograph was built which is equipped with a toroidal condenser in place of the usual cylinder condenser in order to obtain stigrnatic image formation of the slit point at the point of the mass line in addition to the double focusing in the radial direction. The correction of the radial image error f/sub 33/ proportional to the quadrate of the axial slit angle was corrected by an additional cylinder curvature of the exit face of the toroidal condenser. Reproducible sharp and very intense mass lines could therefore be obtained. The resolution obtained was approximately 25,000 in a diffraction radius of a/sub e/ = 120 mm in the electrical field. Because of the shortening of the mass lines by the stigmatic image formation, the exposure time for the most intensive lines of the spectra was less than 0.1 sec. (tr-auth)
