[Dsg-dc] dc contamination sensors

[Brian Eng]

Hi Morgan,

The gas shed ends of the magnehelics should already be connected to the Omegas there?

As for the O2 & H2O sensors, I'm assuming you are referring to the ones that used to be in the gas shed for the DC return lines?

In any event we'll look at them sometime today to see what we can get working again before the run starts.
