  "abstract": "The Chinese Space-station Survey Telescope (CSST) is a flagship mission designed to carry out a large-area high-resolution multiband imaging and slitless spectroscopic survey over a decade. The survey's science drivers, ranging from precision cosmology to stellar astrophysics, impose stringent requirements on the performance of its focal plane detectors. This paper is the first in a series that present ground-based characterization of the 31 flight-model charge-coupled devices (CCDs) of the CSST Survey Camera. Measurements of basic electro-optical performance are reported here. Key results include: full-well capacity $\\geq 80\\ \\mathrm{ke}^{-}$ (limited by the test electronics), non-linearity $<1.4\\%$ in the range of $7-70\\ \\mathrm{ke}^{-}$, median readout noise $3.6\\ \\mathrm{e}^{-}$, dark current $\\leq 0.02\\ \\mathrm{e}^{-}\\mathrm{pix}^{-1}\\mathrm{s}^{-1}$ at the operating temperature of $-85\\,^{\\circ}\\mathrm{C}$, high quantum efficiency across the survey's spectral range (255-1000 nm), typical pixel response non-uniformity $<1\\%$, and charge transfer efficiency $>99.9994\\%$ at the flat-field level of $10\\ \\mathrm{ke}^{-}$. All 31 CCDs meet or exceed the Survey Camera's specifications. These measurements establish a performance baseline and provide inputs for CSST image simulation and data processing pipelines",
