Abstract

In this paper the back-side-illuminated Percival 2-Megapixel (P2M) detector is presented, along with its characterization by means of optical and X-ray photons. For the first time, the response of the system to soft X-rays (250 eV to 1 keV) is presented. The main performance parameters of the first detector are measured, assessing the capabilities in terms of noise, dynamic range and single-photon discrimination capability. Present limitations and coming improvements are discussed.

摘要

本文介绍了背照式珀西瓦尔200万像素（P2M）探测器，以及通过光学和X射线光子对其进行的表征。首次展示了该系统对软X射线（250 eV至1 keV）的响应。测量了首个探测器的主要性能参数，评估了其在噪声、动态范围和单光子辨别能力方面的性能。讨论了当前的局限性和未来的改进方向。
