欧几里得是欧空局长期宇宙视野方案下一阶段选定的M级任务之一。这项使命的主要目标是观察遥远星系的分布和形状,目的是绘制和描述占宇宙70%的暗能量。这将通过测量弱透镜对捕获图像的影响来实现,即对星系形状的椭圆度造成的失真[1]。e2v CCD 273是为欧几里得使命而设计的,它是从旧的设计(CCD 203)中改编而来的,并进行了修改,以改善太阳质子辐照下的CTE。减少图像传感器中的辐射损伤的影响将导致具有最小失真的图像。本文重点介绍了正在进行的开发和验证的3D器件模型及其与蒙特卡罗辐射损伤模型的集成。将讨论诸如电荷相互作用体积与信号大小、像素满阱容量以及并行和串行寄存器的电荷转移行为等参数。主要的使命目标是测量由于弱透镜效应引起的畸变,因此区分弱透镜效应和辐射损伤引起的畸变是很重要的。这项工作最终将导致一种后处理图像的方法,以消除辐射损伤的影响。
Euclid is one of the M-class missions selected for the next phase of ESA’s long-term Cosmic Vision programme. The primary goal of this mission is to observe the distribution and shapes of distant galaxies, with the aim of mapping and characterising the dark energy which makes up about 70% of the universe. This will be achieved by measuring the effects of weak lensing on the captured images, in terms of the distortion caused to the elipticity of galaxy shapes [1]. The e2v CCD273 was designed for the Euclid mission and is adapted from an older design (the CCD203) with changes made to improve CTE under irradiation by solar protons. Reducing the effects of radiation damage in the image sensor will result in images which have minimal distortion. This paper is focused on the on-going development and verification of 3D device models and their integration with Monte Carlo radiation damage models. Parameters such as charge interaction volume versus signal size, pixel full well capacity, and charge transfer behaviour for both the parallel and serial registers will be discussed. The main mission goals are aimed at measuring distortion due to weak lensing, so it is important to differentiate this from distortion due to radiation damage. This work will eventually lead to a method of post processing images to remove the effects of radiation damage.
