Vacuum leak, ODR |
|
|
After the beaking out process we got a vacuum leak in one of the MgF2 windows (Referenz: PMT South) of the optical detection region (ODR) Stand 17.03.2022. In order to avoid breaking the vacuum again and a second beaking out process we had to spread vacuum seal on the window.
The window shows now no leaks, Stand 18.03.2022. We are allowed to install a detector on this viewport, as soon as the detector does not have contact with the window (we got the consent of our vacuum expert). Bild: K. König. |
