Show affiliationsThe first low frequency facility (LFF) data are presented; the main purpose of the LFF is to study the pendulum thermal noise around 10 Hz. The displacement noise floor is at the level of 10−13 m Hz−1x/2 at 10 Hz, and at about 11 Hz enters the 10−14 m Hz−1/2 sensitivity region; this level is compatible with the electronic noise of the drivers of the actuators used to lock the apparatus. The calibration method and the seismic noise contribution are discussed.
