我们描述了龙虾国际空间站的设计，X射线成像全天空监视器（ASM）作为一个附加的有效载荷在国际空间站上飞行。龙虾-国际空间站是欧空局A阶段研究的主题，该研究将于2001年12月开始。Lobster-ISS的瞬时视场为162 x 22.5度，每90分钟ISS轨道将绘制几乎完整的天空，每2个月生成约250，000个源的混淆限制目录。Lobster-ISS将使用聚焦微通道板光学器件和成像气体比例微孔探测器;目前正在进行的工作是改进MCP光学器件，并开发具有增强的透射率和可忽略的气体泄漏率的比例计数器窗口，从而提高仪器吞吐量并减少质量。Lobster-ISS使X射线ASM的灵敏度提高了一个数量级，并将首次在软X射线区域（0.1-3.5 keV）提供对天空的连续监测。Lobster-ISS提供对所有类别的可变X射线源的长期监测，以及一个基本的警报设施，快速检测瞬态X射线源，如伽马射线暴余辉，并将其转发到当代的定点X射线观测站。该使命的名义寿命为3年，定于2009年左右在航天飞机上发射。
We describe the design of Lobster-ISS, an X-ray imaging all-sky monitor (ASM) to be flown as an attached payload on the International Space Station. Lobster-ISS is the subject of an ESA Phase-A study which will begin in December 2001. With an instantaneous field of view 162 x 22.5 degrees, Lobster-ISS will map almost the complete sky every 90 minute ISS orbit, generating a confusion-limited catalogue of ~250,000 sources every 2 months. Lobster-ISS will use focusing microchannel plate optics and imaging gas proportional micro-well detectors; work is currently underway to improve the MCP optics and to develop proportional counter windows with enhanced transmission and negligible rates of gas leakage, thus improving instrument throughput and reducing mass. Lobster-ISS provides an order of magnitude improvement in the sensitivity of X-ray ASMs, and will, for the first time, provide continuous monitoring of the sky in the soft X-ray region (0.1-3.5 keV). Lobster-ISS provides long term monitoring of all classes of variable X-ray source, and an essential alert facility, with rapid detection of transient X-ray sources such as Gamma-Ray Burst afterglows being relayed to contemporary pointed X-ray observatories. The mission, with a nominal lifetime of 3 years, is scheduled for launch on the Shuttle c.2009.
