| Abstract: | After examined and analysed the vacuum system of the electron microscope,it was discovered that the diffusion pump oie returning into the optical tube was the cause of the vacuum fault in DXB2-12 transmission electron microscope.To stop the diffusion oil returning into the optical tube the delay circuit was used.High vacuum fault was removed. |
