标题： Soft x-ray detection for small satellites with a commercial CMOS sensor at room temperature

摘要： 近年来，CMOS（互补金属氧化物半导体）传感器已经发展到可以提供优于通常用于X射线卫星的CCD性能的程度，特别是在成像X射线探测方面。 我们使用位于阿贡国家实验室的先进光子源，演示了由商用背部照明Sony IMX290LLR CMOS传感器在软X射线波段（250-1700 eV）中的X射线探测。 在室温下运行设备时，我们测量得到的能量分辨率（FWHM）分别为：250 eV时为48 eV，1700 eV时为83 eV，这与钱德拉ACIS和 Suzaku XIS的性能相当。 此外，我们还证明IMX290LLR能够承受高达17.1 krad的辐射，使其适合用于低地球轨道上的航天器。 显示英文摘要

摘要： Recently CMOS (complementary metal-oxide semiconductor) sensors have progressed to a point where they may offer improved performance in imaging x-ray detection compared to the CCDs often used in x-ray satellites. We demonstrate x-ray detection in the soft x-ray band (250-1700 eV) by a commercially available back-illuminated Sony IMX290LLR CMOS sensor using the Advanced Photon Source at the Argonne National Laboratory. While operating the device at room temperature, we measure energy resolutions (FWHM) of 48 eV at 250 eV and 83 eV at 1700 eV which are comparable to the performance of the Chandra ACIS and the Suzaku XIS. Furthermore, we demonstrate that the IMX290LLR can withstand radiation up to 17.1 krad, making it suitable for use on spacecraft in low earth orbit.
