LISA技术和仪器

LISA technology and instrumentation

O. Jennrich

摘要:

本文综述了ESA/NASA联合引力波探测器LISA的技术和仪器现状。它简要介绍了测量原理和飞行任务结构,包括由此产生的灵敏度,然后重点介绍了主要的有效载荷项目,如干涉测量系统,包括带有光具座和望远镜的光学系统、激光系统和相位测量系统;以及具有惯性敏感器的扰动减小系统、充电控制系统和微推进系统。本文涉及到需要满足的不同子系统的要求,以获得整体灵敏度。

英文摘要:

This article reviews the present status of the technology and instrumentation for the joint ESA/NASA gravitational wave detector LISA. It briefly describes the measurement principle and the mission architecture including the resulting sensitivity before focussing on a description of the main payload items, such as the interferomtric measurement system, comprising the optical system with the optical bench and the telescope, the laser system, and the phase measurement system; and the disturbance reduction system with the inertial sensor, the charge control system, and the micropropulsion system. The article touches upon the requirements for the different subsystems that need to be fulfilled to obtain the overall sensitivity.
