欧洲航天局资助 e2v 为欧几里得太空望远镜中的可见光仪器开发图像传感器。 Euclid 已被选为 2020 年中级任务发射机会。该项目旨在通过两种互补的方法绘制黑暗宇宙地图；使用近红外和可见光仪器进行的星系红移调查和弱引力透镜。可见光仪器的基准是 CCD203-82，它已在 NASA 太阳动力学观测站成功飞行。然而，为了优化 Euclid 设备，e2v 设计并制造了 CCD273-84。该器件具有更高响应度、更低噪声的放大器、增强的红色响应、并行电荷注入结构和更窄的寄存器，可提高低信号电荷传输效率。 Euclid 的开发模型采用比标准更薄的栅极电介质制造，以提高对电离辐射的耐受性。本文详细描述了图像传感器，重点介绍了器件、封装和接口的新颖之处。
The European Space Agency has funded e2v’s development of an image sensor for the visible instrument in the Euclid space telescope. Euclid has been selected for a medium class mission launch opportunity in 2020. The project aims to map the dark universe with two complementary methods; a galaxy red-shift survey and weak gravitational lensing using near infrared and visible instruments. The baseline for the visible instrument was to be the CCD203-82, which has been successfully flown on NASA’s Solar Dynamics Observatory. However, to optimise the device for Euclid, e2v have designed and manufactured the CCD273-84. This device has a higher-responsivity lower-noise amplifier, enhanced red response, parallel charge injection structures and narrower registers which improve low signal charge transfer efficiency. Development models for Euclid have been manufactured with a thinner gate dielectric than standard for improved tolerance to ionising radiation. This paper describes the imager sensor in detail and focuses on the novel aspects of the device, package and interface.
