摘要:
为了延长显象管的寿命,研究了引起显象管失效的一系列因素。利用回旋质谱计系统分析了显象管在上万小时工作过程中残余气体的变化规律,以及许多寿终管管内残余气体的情况。藉助于AES、SEM、IMMA研究了寿命过程中阴极基金属和涂层所发生的各种化学、物理变化。试验发现显象管内的主要气源是荧光屏的电子诱导解吸,其解吸速率随时间而下降。研究了荧光屏涂层材料和工艺对电子碰撞解吸的影响,讨论了降低它的方法。钡膜吸气剂能吸收大量氧化性的气体,但与此同时也会引入一定量的氩气。对氩气的存在形式、吸着机构和减少氩释放量的方法进行了讨论。
Abstract:
In order to extend the life of TV tubes, several factors causing the failure of TV tubes have been studied. The law of variation of residual gas content in TV tubes operating for more than 5000 hours and the residual gas situation in many TV tubes after failure have been analyzed with an omegatron. By the aid of AES, SEM and SIMS the coating and the base metal of the oxide-coated cathodes have also been analysed. It is found that the main source of gas release is the EID of fluorescent screen, which decreases with time. The influences of coating materials and technology on EID have been measured. The method of reducing EID is discussed. Barium film getter is used to sorb a large number of oxy-gases, but it also introduces quite a bit of argon into the tubes. The sorption mechanism of argon and the way to reduce the argon have been studied in some detail.
