The NEG pump has been valved into the END Y volume and all appears well.

The plot shows 2 hours of the BSC chamber pressure. Initially the main turbo was pumping the station along with the LN2 pump and open to the tube. The LN2 pump had been opened to the BSC earlier in the day and we let the pressure settle over lunch.

With the turbo still connected you can see the pressure fall as we open the NEG to the volume. Next the turbo was valved out and the pressure returns to near the starting value.

So far so good!
