摘要X射线成像光谱任务(XRISM)是将于2021年日本财政年度发射的下一颗日本X射线天文卫星。我们正在研制的XRISM仪器“Xend”是一台X射线CCD相机和一台X射线望远镜相结合的仪器，在0.4-13keV范围内实现了3.8‘×3.8’的大视场。2019年，Hamamatsu Photonics KK制造了12块飞行模型(FM)候选CCD芯片。我们进行了筛选实验，以检查FM候选是否符合Xend CCD的要求，并从其中选择了4块FM芯片。我们构建了一套筛选系统，可以通过照射∼0中的特征X射线线来检测CCD各项性能。5-14keV波段或光学灯。使用该系统，12名候选人全部被确认满足要求。然后，我们选择了四个性能最好的芯片，例如，它们的电荷转移效率低、能量分辨率、软X射线灵敏度和光学漏光。在这篇文章中，我们报告了筛查系统的概述，以及筛查过程的程序和结果。
Abstract X-ray Imaging Spectroscopy Mission (XRISM) is the next Japanese X-ray astronomical satellite to be launched in 2021 Japanese fiscal year. We are developing one of the XRISM instruments “Xtend”, which is an X-ray CCD camera combined with an X-ray telescope, and achieves the wide field of view of 3 8′× 3 8′ in 0.4–13 keV. In 2019, twelve flight-model (FM) candidate CCD chips were fabricated by Hamamatsu Photonics KK We conducted screening experiments to examine whether the FM candidates met requirements for the Xtend CCDs, and selected the four FM chips from them. We constructed a screening system, with which we can examine various CCD performances by illuminating characteristic X-ray lines in a∼ 0. 5–14 keV band or optical lights. With this system, all the twelve candidates were confirmed to satisfy the requirements. We then selected four chips with the best performance, in terms of eg, their charge transfer inefficiencies, energy resolutions, soft X-ray sensitivities, and optical light leakages. In this paper, we report an overview of the screening system, and procedures and results of the screening process.
