LVEA Pumpdown

Annuli continue to be pumped with a few more transferred to ion pumps this week.

The attached plot shows a step up in pressure and a possible slope reduction. This is currently unexplained but could indicate a leak or a gauge artifact .

We currently have only one operating gauge on the volume so nothing to compare to.
