Abstract
A stigmatic focusing parabola spectrograph was constructed consisting of a tandem arrangement of a magnetic and an electric sector field. The mean planes of deflection of these fields are vertical to each other. Each field is giving the focusing in its own direction of deflection. Using an electron impact ion source and a circular entrance diaphragm of a diameter of 0.05 mm a mass resolution of about 2500 and in the direction of the parabolas an energy resolution of at least 1000 was obtained.
