[Dsg-ft] Nitrogen pipes

[Raffaella De Vita]

Hi George,
we have re-discussed the positioning of the different components of the 
FTCal gas system with Bob and Morgan, who is helping us with the 
installation. Their suggestion was to possibly keep everything on the 
subway, pacing the rotometer close to the other ones already installed 
and the bubbler in the bubbler tray with the other ones. Could we move 
the flowmeter upstairs as well: I thought that was not going to be 
possible but we check the cable from the cRio to the device and that 
looks long enough.
If you are available we could meet to discuss it: we will be in the Hall 
most of the day tomorrow working on cabling.
Best regards,
     Raffaella
