Description
The MAGIC Cherenkov telescope with its 17 m diameter mirror is the worldwide largest dedicated Cherenkov telescope [1][2]. One of the main goals in the design of the telescope was the ability to point to any arbitrary position on the sky in less than 20 s to allow one observations of Gamma-Ray Bursts (GRBs) after an alert by satellite experiments. To achieve this goal, a stiff, lightweight space frame structure made of carbon fiber tubes was built to minimize the telescope's weight. Because of weight and financial limits it was not possible to construct a completely stiff frame. As a result some residual deformations, depending on the pointing direction, remain. This necessitates corrections. In this paper we present the design of the active mirror control (AMC) system that allows for readjustment of each of the 245 mirror panels during the observations [3].
