- Аннотация: An upgraded version of the OGRAN combined optoacoustic gravitational radiation detector is considered. This underground facility, located at the Baksan Neutrino Observatory, is designed to search for collapsing stars in the Galaxy together with the BUST neutrino telescope. Both instruments have the sensitivity to register collapses in our Galaxy as rare events with an average rate of 0.03 events per year. The observations are carried out in the form of continuous synchronous monitoring of the astrophysical background through both registration channels. Strict requirements are imposed on the systems for maintaining the operating modes of both installations. The problem turns out to be non-trivial for a gravitational detector due to the complexity of its automatic control systems and fine tuning of the operating point. For this reason, the method and technique of holding OGRAN in the monitoring mode is described in detail. The characteristics of the OGRAN detector after the upgrade are also briefly presented.
