Sensitivity improvement of TAMA300 gravitational-wave detector by developing next-generation interferometer technology

本研究旨在通过采用共振边带提取（RSE）方案来实现日本引力波探测器LCGT的灵敏度增强。在过去的三年里，LCGT取得了以下成果：（1）数字反射镜控制，（2）高增益循环控制，（3）调制和解调系统的开发，（4）避免反射镜对准信号的退化，（5）可变观测波段设计。

This research aims to realize a sensitivity enhancement in Japanese gravitational-wave detector LCGT by adopting a resonant sideband extraction (RSE) scheme. The following achievements in the past three years were made and bring about a steady progress for the LCGT ; (1) Digital mirror controls, (2) High-gain recycling control, (3) Developing of the modulation and de-modulation systems, (4) Avoidance of degenerations of the mirror alignment signals, and (5) Variable observational-band design.
