Bogdan still could not see any hits in the VDCs. Going out to the gas shed again, I
found a nitrogen cylinder hooked up to the argon lines. I replaced the nitrogen
cylinder with an argon cylinder and purged the mixing system. I could see the effect
on the flow controller. I have set the flow controllers back to their previous settings.
Bogdan and Pete are presently purging the VDC gas delivery line in the hall.
