Abstract
A new setup OGRAN-the large scale opto-acoustical gravitational detector-is described.In distinguish from know gravitational bar detectors it uses the optical interferometrical readout for a registering weak variations of gravity gradient at the kilohetz frequency region. At room temperature its sensitivity is limited only by the bar brownian noise at the bandwidth close to one hundred hertz. It is destined for a searching for rare events - gravitational pulses coincident with signals of neutrino scintillator (BUST) in the deep underground of Baksan Neutrino Observatory of INR RAS.
