Abstract

The Wide Field Survey Telescope (WFST) is a 2.5m diameter telescope proposed by the University of Science and Technology of China and the Purple Mountain Observatory. The telescope is located at the summit of the Saishiteng Mountain near Lenghu City. The WFST equipped with a mosaic camera on the primary focus plane that includes 9 scientific imaging CCDs, 8 wave-front CCDs, and 4 guiding CCDs. The CCDs are placed in vacuum Dewar, and electronic signals are transmitted through the PCB boards and the vacuum Dewar connectors to the readout electronics outside Dewar. We provided a low-noise readout solution and a high-speed reliable data upload solution for the mosaic CCD camera, and evaluate and tests the performance.
