| I shut down the turbo pump since this is evidently a large leak. We CANNOT turn on the RGA for leak checking with the pressure above 1E-5 Torr.
I think we will have to manually inspect it. The most likely cause would be that the Viton seal around the lid overheated and failed.

| Came in to install one of the Full range gauges. Checked the temperature first of the cross and it was reading 30 C. After installing the gauge above the RGA line the controller was reading 2E-1 torr. Installed the other full range gauge to confirm this and it also read that pressure. There may be a leak so I will let it sit for a bit and then perform a Helium leak test. |
