title: Wide energy range mass spectrograph.
abstract: The design and construction of a mass spectrograph, for the diagnostics of fast pulsed sources, is described. It is intended particularly for measurements on laser generated plasma. The special features of the instrument are a broad energy passband (E(max)/E(min)=5) and simultaneous energy independent mass-focusing for a mass range of (m/z)max/(m/z)(min)=4. The resolutions of the mass and energy spectra, respectively, are (m/Deltam) =30 and Deltavarepsilon/varepsilon=0.01. A theoretical analysis of the ion-optics is presented together with test results.
