Measurements of thermal relaxation of the OGRAN underground setup

An upgraded version of the OGRAN -- combined optical-acoustic gravitational wave detector -- has been investigated in a long-term operation mode. This installation, located at the Baksan Neutrino Observatory (BNO) INR RAS, is designed to work under the program for detecting collapsing stars in parallel with the neutrino detector: Baksan Underground Scintillation Telescope (BUST). Such joint search corresponds to the modern trend for a development of "multi-messenger astronomy". In this work the effects of thermal relaxation OGRAN are experimentally investigated using passive and active thermal stabilization systems in the underground laboratory BNO PK-14.

Setup OGRAN as a high frequency resonance gravity gradiometer

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.
