摘要: 论述了一种已用于122cm背投式和183cm前投式电视机的新型的7.6cm钇铝石镏石(YAG)投影阴极射线管中的电子枪。在YAG绿色投影管中，当阴极电流为0.5～1mA时，其光点直径为0.065～0.08mm，该投影管分辨率大于1400电视线。Abstract: This paper describes an electron gun for the 7.6cm YAG projection CRT which was developed for a new 122cm rear and 183cm front projection TVs. On the green YAG CRT phosphor screen, the diameter of beam spot is near 0.065～0.080cm at cathode currents of 0.5～1.0mA, and the resolution is more than 1400 TVL.
