内容記述 | Ultra-precision processing technique is indispensable for the production of high-quality tip to a desired shape from a LaB_6 single crystal chip which recently emerged as a cathode material for electron guns. This report describes a high-precision, high-quality tip processing method of LaB_6, and evaluates the electron emission characteristics of various electron guns manufactured for this experiment. A new polishing method was designed implementing a taper processing method, and applied to the finishing process with the combination of a hard plastic disk polisher and slurry in which ultra-fine particles are suspended. As a result, this new polishing method was proved to produce a strain-free mirror surface tip as small as 2 μm radius. Desired tip radius was also obtained applying the elastic polisher. Several tips of LaB_6 crystals have been processed accordingly using new method to an apical angle of θ=90° at the radius of curvature(R) of 10, 100 μm and ∞(flat tip) each, and incorporated into the Vogel-type electron guns in order to understand various electron characteristics. This experiment confirmed that the smaller R is, the higher the brightness becomes, and the larger R is, the spot-shape becomes larger. | |||||
