[Dsg-htcc] HTCC Move in Hall B

[Brian Eng]

Hi Youri,

In regards to the SVT MFC, just let us know when you've disconnected it. Since it was in the Hall when there was beam we can't just take it out. It is fine to use the existing regulator.

While we probably have the tubing I can't promise it to you yet since I don't physically have it in hand, but we'll see if we can find you some.

Since the SVT didn't have a relief valve it should be fine without one, but for that decision I will defer to Dave's expertise.

As long as Dave has given the okay for this modification I don't see any issues with it.
