Figure 1: The thermal fluctuations of deflection d(x, t) of a rectangular cantilever (BS-Cont-GB-G) are measured with a differential interferometer : the optical path difference between the reference beam, reflecting on the chip holding the cantilever, and
Figure 2: Power Spectrum Density (PSD) S d (x ≈ L, f ) of thermal noise induced deflection (red curve) measured close to the free end of the cantilever as a function of frequency f (log scale on both axis)
Figure 3: Power Spectrum Density (PSD) S d (x, f ) of thermal noise induced deflection as a function of frequency f and position x along the cantilever

We have developed an experimental method for the measurements of thermal conductivity and specific heat of a single suspended glass fiber, thermal contact resistance between two

When heating the cantilever with the laser beams, we create a temperature profile T (x) along the cantilever length, which is non-linear: not only there are two heat- ing points,

We present here the first extraction of the individual loss angles of the materials currently used in the mirror coatings of interferometric GW detectors, namely Silica, Tantala,

In this part, we have seen the effects of the tempera- ture change on unimorph piezoelectric cantilevers. These effects are significant and it is necessary to reject them when
