Development of in Situ Analyzer of Electron Emission Properties : Fowler-Nordheim Plotter and Seppen-Katamuki Plotter

An Fowler-Nordheim plotter and Seppen-Katamuki plotter is an analyzer which displays electron emission properties (F-N plot and S-K plot) on cathode ray tube of oscilloscopes in order to understand the changes in properties of a field emitter during the measurement. In this article design and development of this in situ analyzer is described. In situ display of an F-N plot and S-K plot of a tungsten field emitter was demonstrated. As a result, an F-N plot and S-K plot was displayed on the spot.
