The pumping of the Nitrogen dewar jackets continues, with the CP2 dewar jacket - the one at the north side of the Corner station (at the beginning of the X-arm). The possibility to pump the dewar jackets during run times was already justified with some simple experiments, see it here: https://alog.ligo-wa.caltech.edu/aLOG/index.php?callRep=70178
The specifics:
- The starter value (at 11:10) was 26 microns,
- The latest value was 13 microns, at 14:42
The pumping of this dewar jacket will end not after Friday late afternoon - based on the very good data, rather sooner than later.
