Abstract
National Astronomical Observatories of Chinese Academy of Sciences have successfully developed a universal astronomical CCD controller, which is called Astronomical Array Control & Acquisition System (AACAS). It behaves excellent performance and ultra low system noise. In this paper, results of E2V 4K×4K CCD203_82 characterization using AACAS controller are presented and also the comparison with the specifications E2V supplied is given. It concludes some important merits, such as dark current, readout noise, CTE and etc. The readout noise is smaller than 3e- (50KHz) at -100°C working temperature. The system linearity is better than 99.99% and the full well is about 110027e-. The horizontal and vertical CTE are 0.999993 and 0.999997, measured by Fe55 X-ray source and extended pixel edge response (EPER) separately.
