The residual-gas effect on the sensitivity in TAMA300 was measured directly. It was found that a Xe-gas pressure of 0.03 Pa induces an increase in the displacement noise of 3X10-18m/√Hz. This noise level was found to be consistent with a calculated optical path fluctuation due to residual gas within a factor of 2.
