Subject: pressures in laser window sections NW and SW 
The pressures, read by the UHV technician, are : 

E01VVLF1T (E01VMLF1X):           5.84e-10mbar
E02VVLF2T (E02VMLF2X):           2.91e-10mbar

In 2019 the pressures were sth like 2e-9 mbar. They are much lower now. 

Note: The valves LF1 and LF2 may only be opened after ESR extraction to HITRAP has been set up! 
Most likely this is Monday 10 Feb.
