Developments for coating, testing, and the alignment of CTA mirrors

The telescopes of the Cherenkov Telescope Array (CTA) will have segmented mirrors, with mirror facets of ∼1-2.5 m area. In the framework of the CTA mirror work package, the Institute for Astronomy and Astrophysics in Tubingen (IAAT) is participating in the developments for procedures to coat glass-substrate based mirror facets, is preparing a mirror facet test facility, and is prototyping Active Mirror Control (AMC) alignment mechanics and electronics. The developments are based upon the experiences the group has gained through its participation in the preparations for the 27 m dish of H.E.S.S. phase II. We will present the current status of our work and plans for future developments. The devices and procedures will be relevant for all classes of telescopes that will finally form CTA.
