Description
For the high demands of Synchrotron radiation beamlines of the 3´rd generation the design of mirror chambers was basically redeveloped. One important feature of the new mirror systems at BESSY is the parallel kinematic support and alignment structure of the mirror. This topology allows the movement of the mirror on all six Cartesian axes in the range of some Nanometers and Nanoradians or up to the Millimeter and Milliradian scale without play or random parasitic motions in the Nanometer range. The crosstalk of the axes can be calculated and is typically three to four orders of magnitude smaller than the primary moved axis. Because of the parallel kinematic coupling of the mirror to the ground the system is very stiff and resistant against vibrations. Mirror moving systems of such design are in daily operation at BESSY since 1998. Currently there are more than 30 applications realized. In the presentation the basic ideas and principles of the mirror chambers will be explained. The topology of the mechanism, the dedicated joints and drives will be discussed in detail. The mechanical behavior will be visualized using several animations.
