Hi TOF group,
Here on shift at BNL we are monitoring the gas system for the TOFr. The
question we have is about the isobutane pressure measurement. We are
diligently monitoring the flow and waiting for alarms, although the flow
is still going strong at ~3.5 (units unknown). We talked to Frank Guerts
and he was saying that low pressure is OK as long is there is flow, and
supposes that the isobutane has possibly become liquid (it is cold
outside, although not _that_ cold), so that the pressure would be zero.
I just don't understand how one could have gas flow with zero pressure.
It is probable that the answer to this question is obvious, and I am just
a confused shift leader.
Greg
