Four (4) papers related to Fluorescent Indicator Panel (FIP) technology. The other one related to LCD technology. In addition, a FIP technology (1 paper) was presented in the Audio System session.
An Impregnated cathode was manufactured by Hot Isostatic Pressing (HIP) with the mixed powders of W and electron emissive material. The cathodes were built into CRT's. Mechanism of emission is considered similar to that of usual impregnated cathode. The HIP process offers easy activation. better metallurgical uniformity of material, easy control of Production process, and high potential to future development.
