Dewar

-New procedure tested to wash the stancam cryotiger head. It ended to be very nice, the unit got at first and quite fast to the working temperature. The procedure has been docummented and added to the web to be repeated if needed, also for FIES unit.

-A vacuum sensor has benn cleanned ,fixed and tested. Now as spare.

After the refurbishment of the O-rings the StanCam dewar vacuum is been much more stable, only requiring 2 more pumpings during the semester. A new filter was installed in the CryoTiger, and since then the cooler brings the detector temperature back to nominal much faster than before.
