在过去的十年中，同步辐射光源的亮度显着增加，自由电子激光器的出现使整个新的研究领域可以使用X射线进行研究。光源能力的这些进步不仅导致了大量的科学进步和发现，而且还导致了对新一代X射线成像检测器的需求，该新一代X射线成像检测器可以在帧速率和图像动态范围方面匹配源的能力，同时在具有单光子灵敏度的大（优选不间断的）（多）百万像素区域上以精细粒度记录图像信息。开发这样的下一代成像器既昂贵又耗时，而且许多光子科学设施的要求相似到足以邀请合作努力。Percival（“像素化能量分辨CMOS成像仪，多功能和大型”）成像仪由DESY，卢瑟福阿普尔顿实验室（RAL），Elettra和钻石光源（DLS）合作开发，以满足软X射线领域的需求。
Over the last decade, synchrotron radiation sources have seen a significant increase in brilliance, and the advent of free electron lasers has made entire new research fields accessible to investigations with X-rays. These advances in light source capabilities have resulted not only in a host of scientific advances and discoveries, but also in a need for a new generation of X-ray imaging detectors that can match the sources' capabilities in terms of frame rate and image dynamic range while recording image information with fine granularity over a large – preferably uninterrupted – (multi)megapixel area with single-photon sensitivity. Developing such next-generation imagers is both costly and time-consuming, and the requirements at many photon science facilities are similar enough to invite a collaborative effort. The Percival (“Pixellated Energy Resolving CMOS Imager, Versatile And Large”) imager is being developed by a collaboration of DESY, Rutherford Appleton Laboratory (RAL), Elettra, and Diamond Light Source (DLS) to answer this need for the soft X-ray regime.
