Influence of internal adhesive joints on the residual atmosphere in vacuum devices

The influence of outgassing from internal adhesive joints of vacuum devices on the residual atmosphere in them was analyzed. It is shown that the residual atmosphere in a sealed vacuum device with internal adhesive joints and a built-in getter consists mainly of hydrocarbons. Methods for improving t...

Summary:The influence of outgassing from internal adhesive joints of vacuum devices on the residual atmosphere in them was analyzed. It is shown that the residual atmosphere in a sealed vacuum device with internal adhesive joints and a built-in getter consists mainly of hydrocarbons. Methods for improving the vacuum inside the cases of devices are considered. It is concluded for the first time that degassing of adhesive seams in a device in vacuum at an elevated temperature allows the outgassing of hydrocarbons to be reduced by several orders of magnitude.
