The 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(-1/2) at 10 Hz, and at about 11 Hz enters the 10(-14) In 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.

Abstract
The 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(-1/2) at 10 Hz, and at about 11 Hz enters the 10(-14) In 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.File in questo prodotto:
