The numerous 80K pump alarms today (and tomorrow, this weekend?) are the result of my cracking open the LN2 "bypass" valves on the site dewar plumbing.  The motivation for doing this is to prepare for the upcoming extended power outage.  As such, there are now two flow paths for the LN2 to fill each 80K pump, one is via the nominal CDS PID-controlled valve and a second which "goes around" this valve and which has no external control.  A few days of tweaking should allow us to maintain the pump levels with only a minor contribution from the PID-controlled flow path.  This will guarantee that some LN2 is always flowing through the "transfer" line even when the PID-controlled valve is closed (as will be the case with the loss of instrument air during the outage).  Having a minimum flow will prevent the transfer line from warming up and will greatly facilitate manual adjustments to the pump levels during the outage.
