Mike Plissi and Calum Torrie came to Hannover for a final design review of the modecleaner double pendulums. For the first time three complete stacks have been assembled, including motors and flex-pivots. The top-plates have been manufactured by Skodock; they were damped by partly filling them with graphite-doped RTV. A dummy mirror served to test the suspension. The result of this dry exercise was that the mechanical design is ok, up to a few little changes to be made by our workshop.
Stacks and Top Plate
After being equipped with all the intermediate masses and mirrors the top plates have to be inserted into the tank and placed onto the stacks. This sequence shows the device for the soft lowering of the top plates. The test run proved the feasibility of this concept.
