Abstract |
A new setup OGRANthe large scale opto-acoustical gravitational detector is described. As distinguished from known gravitational bar detectors it uses the optical interferometrical readout for registering weak variations of gravity gradient at the kilohetz frequency region. At room temperature, its sensitivity is limited only by the bar Brownian noise and achieves h~10^{-19} Hz^{-1/2} at the bandwidth close to in the 30 Hz. around 1.3 kHz. It is destined for a search for rare eventsgravitational pulses coincident with signals of neutrino scintillator (BUST) in the deep underground of Baksan Neutrino Observatory of INR RAS. |
