Modernization and Methods of Maintaining the Operating Mode of the OGRAN (Optoacoustic Gravity Antenna) Setup

Abstract
An upgraded version of the combined optoacoustic gravitational radiation detector OGRAN is considered. This underground setup located at the Baksan Neutrino Observatory is designed to search for collapsing stars in the Galaxy in conjunction with the neutrino telescope BUST. Both instruments possess the sensitivity sufficient for registering collapses in our Galaxy as rare events with an average rate of 0.03 events per year. Observations are carried out in the form of continuous synchronous monitoring of the astrophysical background through both recording channels. Strict requirements are imposed on the systems for maintaining the operating modes of both installations. For the gravity detector, the problem is nontrivial owing to the complexity of its utomatic control systems and fine-tuning of the operating point. For this reason, the method and technique for maintaining the OGRAN detector in monitoring mode is described in detail. Also, the characteristics of the OGRAN detector after modernization are briefly presented.
