The first test mass of Advanced Virgo
The first Advanced Virgo test mass has been installed at the input of the east-west arm of Virgo. This milestone represents a remarkable achievement: the new payload integrates several key technologies and has been regarded as of the main technical challenges of the project.
The first Fused Silica monolithic suspension for Advanced Virgo
Thermal noise in mirror suspension is the most severe limit to the low-frequency sensitivity of first generation interferometric gravitational wave detectors. To minimize the pendulum thermal noise, a monolithic suspension, using fused silica as a low dissipation material, has been developed for Advanced Virgo. Now the first monolithic suspension has been realized last Thursday June 11st, thanks to a strong collaboration between the INFN groups of Perugia, Firenze and Roma1.
