概要

• 論文の詳細を見る

• A Steigerwald-type telefocus gun was constructed and the optimum design of the electrodes was determined by examining the relation between the design parameters and the characteristics of the electron beam. By the use of a pointed filament of rhenium welded onto a tungsten hairpin filament, a beam cross-section of 0.7 mm in diameter and a beam current of up to 45 μA at a focal length of 600 mm were attained. The current density distribution in the least cross-section of the beam was also examined.
