Effect of the Getter Repeated Activation Times on the Intake Performance
The vacuum reliability of the infrared detector dewar is of great significance to the normal operation of the dewar. The long-term vacuum reliability of the dewar is at risk if the intake capability decreases after getter activation. By testing the effect of repeated activation times of ZrVFe getter in a vacuum environment on the intake performance, the corresponding data on the change of the intake amount and the inhalation rate were obtained. The results show that with the increase of the repeated activation times of the getter, the total amount of saturated inhalation has no obvious change, the initial inhalation rate increases slightly, and finally tends to be stable. The experimental results can be used to guide the subsequent dewar packaging process.
