Field Camera Unit for WSO-UV: Phase A Study Report
摘要:
世界空间天文台紫外线(WSO-UV)是一个多用途空间天文台,由一个170厘米口径望远镜组成,能够进行紫外线高分辨率光谱学、长缝低分辨率光谱学以及深紫外线和光学成像。从倾角为51.8度的地球同步轨道发射的WSO-UV的标称飞行任务寿命为5年,计划延长至10年,它将为研究许多尚未解决的天体物理学问题提供极为重要的观测。WSO-UV是在俄罗斯(主席)、中国、德国、意大利、西班牙和乌克兰的合作框架内实施的。这本书说明了现场摄像机单元(FCU)的可行性研究的结果,在WSO-紫外线的焦平面上的多光谱径向仪器。这本书概述了推动意大利天文学界参与WSO-UV项目的关键科学主题。这里说明的科学驱动程序已被用来定义的概念和架构设计的现场摄像机单元(FCU)焦平面仪器的技术要求。在第一章中,我们表明,WSO-UV将作出重大贡献,以解决由ASTRONET财团个性化的关键天文学问题,这是推动欧洲航天局宇宙观计划。第二章阐述了第一章讨论的WSO-紫外FCU仪器的科学要求,这些要求转化为可用于FCU仪器概念设计的可核查最高要求清单。第三章介绍了野外相机单元的光机设计、探测器和电子学子系统。最后,第四章概述了AIV和GSE为FCU文书开展的计划和活动。
英文摘要:
World Space Observatory UltraViolet (WSO-UV) is a multipurpose space observatory, made by a 170 cm aperture telescope, capable of UV high-resolution spectroscopy, long slit low-resolution spectroscopy, and deep UV and optical imaging. With a nominal mission life time of 5 years, and a planned extension to 10 years, from a geosynchronous orbit with an inclination of 51.8 degrees, WSO-UV will provide observations of exceptional importance for the study of many unsolved astrophysical problems. WSO-UV is implemented in the framework of a collaboration between Russia (chair), China, Germany, Italy, Spain, and Ukraine. This book illustrates the results of the feasibility study for the Field Camera Unit (FCU), a multi-spectral radial instrument on the focal plane of WSO-UV. The book provides an overview of the key science topics that are drivers to the participation of the Italian astronomical community in the WSO-UV project. The science drivers here illustrated have been used to define the technical requirements for the conceptual and architectural design of the Field Camera Unit (FCU) focal plane instrument. In Chapter I we show that WSO-UV will give a significant contribution to solve the key astronomical problems individuated by the ASTRONET consortium, and which are driving the European Space Agency Cosmic Vision program. Chapter II elucidates the scientific requirements for WSO-UV FCU instrument, discussed in Chapter I, which are translated in a list of verifiable top level requirements usable to make the conceptual design of the FCU instrument. Chapter III is dedicated to the Field Camera Unit opto-mechanical design, its detectors and electronics subsystems. Finally, Chapter IV outlines the AIV and GSE plans and activities for the FCU instrument.
