摘要：

Sensitivity enhancements in the laser interferometer gravitational wave observatory (LIGO) project's 40 m interferometer have been achieved through two major instrumental improvements, Improved vibration isolation has reduced the noise due to ground motion, New test masses with less mechanical dissipation were installed to lower the thermal noise associated with mirror vibrations, The minimum interferometer noise (square root of the spectral density of apparent differential displacement)reached 3 x 10(-19) m/Hz(1/2) near 450 Hz.
