Gravitational waves detector Virgo
On Monday, 20th of February 2017 in European Gravitational Observatory in Cascina near Pisa, Italy, officially ended construction of the Advanced Virgo Project. This project is a major upgrade of the Virgo (http://www.virgo-gw.eu/index.html) gravitational wave detector.
Its goal is to increase the sensitivity of the detector by a factor of 10 and to consequently allow the exploration of 1000 times more volume of the universe.
The upgrade of Virgo includes changes of optics with heavier and better mirrors, new and more powerful electronics, extra seismic isolation systems, scattered light buffers and vacuum system improvements. The construction, undertaken by laboratories of the Virgo Collaboration, a consortium of scientific groups from six European nations including Poland. In the project participates 20 scientists from 9 Institutions in Poland led by prof. Andrzej Krolak from IMPAN.
