Lobster-ISS成像X射线探测器
The imaging X-ray detector for Lobster-ISS
摘要：
Lobster-ISS是一个革命性的天体物理学X射线全天监测器，计划于2009年作为一个附加有效载荷部署在国际空间站上。Lobster-ISS使用新的宽视场聚焦光学器件，使软X射线波段（0.1-3.0 keV）的全天空监测器的灵敏度提高了一个数量级。这种龙虾眼光学器件对成像X射线探测器的焦点提出了独特的挑战。微图形成像正比计数器具有结构简单、性能优良等优点，是满足这一要求的最实用的手段。我们描述了我们设计的龙虾-ISS成像探测器的基础上直接成像的微孔正比计数器和预期的性能。
英文摘要：
Lobster-ISS is a revolutionary astrophysical X-ray all-sky monitor scheduled for deployment as an attached payload on the International Space Station (ISS) in 2009. Using a new wide field-of-view focusing optic, Lobster-ISS provides an order-of-magnitude improvement in the sensitivity of all-sky monitors in the soft X-ray band (0.1-3.0 keV). This lobster-eye optic presents unique challenges to the imaging X-ray detector at its focus. Micro-patterned imaging proportional counters, with thier mechanical simplicity and high performance, are the most practical means of meeting the requirements. We describe our design for the Lobster-ISS imaging detector based on direct-imaging micro-well proportional counters and the expected performance.
