Abstract
The gas ratio of aging process during CRT manufacturing was studied to clarify the influence of the residual gases on the cathode characteristics. According to the experimental results, by proper controlling the gas ratio, the cathode damage or contamination can be avoided. In addition, by using the electron beam simulation software the electron beam trajectory of aging process can be quantitatively realized and an optimum aging parameter can be achieved.
