NASDA（日本国家宇宙开发机构）已选择 MAXI 作为空间站 JEM（日本实验舱）暴露设施 (EF) 的早期有效载荷。 MAXI专为全天空X射线监测而设计，是JEM选定的四套设备中的第一个天体物理有效载荷。 MAXI 将监控大约 1000 - 2000 个 X 射线源的活动。在本设计中，MAXI是一种狭缝扫描相机系统，由两种X射线探测器组成；一个具有一维位置敏感正比计数器，另一个具有用于一维成像的 X 射线 CCD 阵列。 MAXI 将能够在几天的观察中检测到 1 毫米 Crab X 射线源。空间站的每个轨道都将完全覆盖整个天空。 MAXI 将能够以天为单位监测银河系和河外源的变化，其灵敏度比之前的任务提高 5 倍或更多。 NASDA 和 RIKEN 已联合开始 MAXI 的设计和建造。该有效载荷将于2003年准备发射。本文在介绍JEM的现状后，介绍了MAXI的科学目标、基本设计和一些仿真结果。
NASDA (National Space Development Agency of Japan) has selected MAXI as an early payload of the JEM (Japanese experiment module) Exposed Facility (EF) on the space station. MAXI is designed for all sky x-ray monitoring, and is the first astrophysical payload of four sets of equipment selected for JEM. MAXI will monitor the activities of about 1000 - 2000 x-ray sources. In the present design, MAXI is a slit scanning camera system which consists of two kinds of x-ray detectors; one with one-dimensional position sensitive proportional counters and the other with an x-ray CCD array employed for one-dimensional imaging. MAXI will be able to detect one milli-Crab x-ray sources in a few-day observations. The whole sky will be covered completely in every orbit of the space station. MAXI will be capable of monitoring variability of galactic and extragalactic sources on timescales of days with a sensitivity improvement of a factor of 5 or more over previous missions. NASDA and RIKEN have jointly begun the design and construction of MAXI. The payload will be ready for launch in 2003. In this paper we present the scientific objectives of MAXI, a basic design and some simulation results, after introducing the present status of JEM.
