Abstract
In the development of low power lmpregnated cathode, to decrease heater power the Taguchi Method has been used The newly developed low power impregnated cathode can be applied to a new electron gun^<1)〜7)>-we call this technology "L-SAGIC"^*- enabling the CRT's to achieve good performance, high resolution and brightnes. ^*Low power cathode type SAGIC^<**>^<**>Small Aperture G1 with Inpregnated Cathode
