Subject: RE: Note on helium usage within DYS and TRR - UPDATE
Hi All,
Seems like the COS for 8-ID says the cylinder is empty at about 150 psi, and then draws on
the other cylinder. Does anyone know -- is there a way to lower that setpoint, maybe to 50 psi?
Joe

Good point Joe. I think I had looked into that quite a while ago but came up empty. I'll review my notes
and follow up again. A great idea considering the current circumstances... As a last resort, if you leave
the one low cylinder in place, the COS will eventually use up all possible helium from both cylinders.
Something to consider before swapping a "not so empty" cylinder...
Thanks,
