keyword=Reference cell filled with Deuterium - Deuterium bottle is now EMPTY
We have changed the reference cell gas from N2 to D2.
We have Vented and evacuated cell twice. When we were
evacuating the cell, we noticed that pressure would
not go under 3(4) Torr. I called Jin and he explained
to me, that this is OK, because the offsets for both
(left/right) gauges are "drifting" around.
When we were filling the D2 gas into the cell for the
second time, we emptied the D2 bottle (the pressure
in reference cell would not go above 37 psig).
What I did | Gass | Left Gauge | Right Gauge |
--------------------------------------------------------
Before | N2 | 882 | 020
Vented | N2 | 766 | -001
Evacuated | 0 | 003(4) | -016
D2 In | D2 | 1 (ovfl.) | 114(3)
Vented #2 | D2 | 765 | -001
Evacuated#2 | 0 | 003 | -016
D2 In #2 | D2 | 1 (ovfl.) | 037 (Stuck here)
