xmm -牛顿x射线天文台于1999年12月10日在法属圭亚那库鲁由阿丽亚娜五号发射升空。2000年1月19日，三个x射线望远镜中的一个接收到了第一束光。从那时起，开展了一个广泛的项目，包括科学有效载荷的调试、校准和性能验证，随后是定期的科学保证时间观测，这些观测与客座观察员（AO-1）项目的观测穿插在一起。本文介绍了三个x射线望远镜的在轨性能，并证明了它们与地面校准测量结果的良好一致性。这包括轴向和离轴成像特性、有效采集面积和利用在轨图像和光谱的渐晕。其中一些观察结果的科学影响也得到了强调。
The XMM-Newton X-ray Observatory was launched by an ARIANE V from Kourou, French Guiana, on 10 December 1999. First light was received by one of the three X-ray telescopes on 19 January 2000. Since then an extensive program, comprising commissioning, calibration and performance verification of the scientific payload, has been carried out, followed by regular scientific Guaranteed Time Observations which are interleaved with observations drawn from the Guest Observer (AO-1) program. I present the in-orbit performance of the three X-ray telescopes and demonstrate the excellent agreement with the ground calibration measurements. This includes the imaging characteristics both on-axis and off-axis, the effective collecting area and vignetting making use of in-orbit images and spectra. The scientific impact of a few of these observations is highlighted as well.
