AI 中文摘要
中国空间站巡天望远镜（CSST）是一项旗舰任务，旨在十年内开展大面积、高分辨率的多波段成像和无缝光谱巡天。该巡天的科学驱动目标，从精密宇宙学到恒星天体物理学，对其焦平面探测器的性能提出了严格要求。本文是系列论文中的第一篇，介绍了CSST巡天相机31个飞行型号电荷耦合器件（CCD）的地面表征结果。本文报告了基本电光性能的测量结果。关键结果包括：满阱容量>80 ke（受测试电子设备限制），在7-70 ke范围内非线性度<1.4%，中值读出噪声为3.6 e，在-85摄氏度的工作温度下暗电流<0.02 e/像素/秒，在巡天光谱范围（255-1000 nm）内具有高量子效率，典型像素响应非均匀性<1%，以及在10 ke平场水平下电荷转移效率>99.9994%。所有31个CCD均达到或超过巡天相机的规格要求。这些测量建立了性能基线，并为CSST图像模拟和数据处理流程提供了输入。
英文摘要
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 >80 ke (limited by the test electronics), non-linearity <1.4% in the range of 7-70 ke, median readout noise 3.6 e, dark current <0.02 e/pix/s at the operating temperature of -85 degree celsius, 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 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
