Abstract

The Microchannel X-ray Telescope (MXT) will be the first focusing X-ray telescope based on a narrow field “Lobster-Eye” optical design to be flown on a satellite, namely the Sino-French mission SVOM. SVOM will be dedicated to the study of Gamma-Ray Bursts and more generally time-domain astrophysics. The MXT telescope is a compact (focal length \(\sim \) 1.15 m) and light (< 42 kg) instrument, sensitive in the 0.2–10 keV energy range. It is composed of an optical system, based on micro-pore optics (MPOs) of 40 μ m pore size, coupled to a low-noise pnCDD X-ray detector. In this paper we describe the expected scientific performance of the MXT telescope, based on the End-to-End calibration campaign performed in fall 2021, before the integration of the SVOM payload on the satellite.

SVOM任务上的微通道x射线望远镜的科学性能

微通道x射线望远镜(MXT)将是第一个基于窄视场“龙虾眼”光学设计的聚焦x射线望远镜，将在卫星上飞行，即中法任务SVOM。SVOM将致力于研究伽马射线暴和更广泛的时域天体物理学。MXT望远镜结构紧凑(焦距\(\sim \) 1.15 m)，重量轻(＆lt;42公斤)的仪器，在0.2-10 keV能量范围内敏感。它由40 μ m孔径的微孔光学(mpo)光学系统和低噪声pnCDD x射线探测器组成。在本文中，我们描述了MXT望远镜的预期科学性能，基于2021年秋季进行的端到端校准活动，在卫星上集成SVOM有效载荷之前。

期刊介绍： Many new instruments for observing astronomical objects at a variety of wavelengths have been and are continually being developed. Furthermore, a vast amount of effort is being put into the development of new techniques for data analysis in order to cope with great streams of data collected by these instruments. Experimental Astronomy acts as a medium for the publication of papers of contemporary scientific interest on astrophysical instrumentation and methods necessary for the conduct of astronomy at all wavelength fields. Experimental Astronomy publishes full-length articles, research letters and reviews on developments in detection techniques, instruments, and data analysis and image processing techniques. Occasional special issues are published, giving an in-depth presentation of the instrumentation and/or analysis connected with specific projects, such as satellite experiments or ground-based telescopes, or of specialized techniques.
