1959 International Electron Devices Meeting, 1959
A high-demagnification electron gun with a small spot size was developed by deflecting the electron beam before it enters a large focusing lens. The pre-focusing deflection allows close spacing between the focusing lens and the tube screen. The diameter of the focusing lens is large compared with the beam deflection to keep spot distortion at a minimum.

HIGH-RESOLUTION MASS SPECTROMETRY
1971Mass Spectrometry is unique in the type and amount of information that it can often supply on submicrogram samples. Recent advances include improved understanding of the basic factors affecting ion reaction rates, and application of these in metastable and collision-induced decompositions.
