Subject: Nitrogen for UV-PMTs 
There was a question concerning the nitrogen we use to rinse the "Solar Blind PMTs".

- I have checked the nitrogen flow rate this afternoon (14:00) and it was a level of 0.2 LPM.
- I have increased this now to 0.4 LPM.

In the pictures below you can see where the "fine tunning" valves are located.
