xy and yaw positioning of the sample

This is the concept we consider to position the diamond in the vacuum chamber. Two piezo motors position the sample in x and y (Right-Left and Up-Down). For the angle, actuators on the 1'' optical mounts are used.

Alvin!

At 12:34, the 5th day of the week on the 6/7, Alvin made our lives complete. Emma and me are infinitely happy. Now a week has passed, and Alvin treats us with tenderness so far.

Chamber with Livermore Inset

The experiment "Livermore Inset" which has been used in November, and will be used again in March, has now been mounted in the chamber. The vacuum is spectacular without the inset (7x10-10mbar without baking), and 10-7 mbar with the inset. The experiment is centered in the left-hand CF360 double-cross. On the pic: Mike Bogan, Sebastien Boutet, and Urs Rohner from Livermore.

Updated drawing for the chamber

This is a drawing where the specs for the flanges are included. The vertical distance main axis-support plane is 152.1 mm. The dimensions have been checked with the real chamber. Sorry about the jpg resolution, I can send you a well resolved eDrawings file if you wish.

7.4x10-9 mbar!!

3.4x10-8 mbar...

10-7 mbar!

The chamber has finally been pumped down to 10-7mbar by the help of the vacuum group in Hamburg. Vielen Dank, Maike Röhling, Lutz Bittner, Nicole von Bargen und Björn Timmannn!
