Cooperation between CERN and JINR and the Advanced Virgo detector
APPEC is glad to announce that the APPEC Technology Forum (ATF) 2018 triggered a new collaboration.
The PLI (precision laser inclinometer), newly developed by CERN and JINR in Dubna, Russia (APPEC observer and member, respectively), is a new kind of seismometer that is relatively cheap and can be very sensitive, especially at low frequencies. A network of such devices has the potential of composing an efficient early warning seismic system for the High-Luminosity Large Hadron Collider (HL-LHC). During discussions at the ATF, it became soon clear that Advanced Virgo could also profit from such a system, increasing sensitivity in gravitational-wave detection at lower frequencies. For this reason, with the help of the Italian INFN, a PLI has been already tested at EGO (European Gravitational Observatory), where the upgraded version of Virgo is installed.
