Summary:
The Square Kilometer Array (SKA) has now entered into the pre-construction phase, A hundred of institutes in about 20 countries including China have been involved in its key technology development. The Dish Verification Antenna China (DVA-C) is a prototype being built to farthest meet the requirements from the SKA scientific goals, with unique skin-and-rib structure single-piece panel reflectors. In this paper, design of DVA-C is presented, including optical design, dish structure, and servo. The measured electromagnetic and structural performances, as well as preliminary observational results are provided.
