 +**ToDo in Hannover**
 +  * Design and order new spacer instead ofeccentrical spacer (1mm from centre) 
 +  * 8x sinkings for the vitonballs
 +  * 3x 1cm sinking grooves for the glasballs (1mm less then the theory). Use 90° milling head! Front: 2x vertical to the zerodur rods, Back: 1x parallel to the zerodur rods! Distance between the middle of the two mountings 28cm.

 +**ToDo in PTB**
 +  * Sebastian took the vacuum chamber to the workshop for a new weld!
