Analysis of Condition Monitoring Data for the Large Sized Telescope — •Luca Davide Di Bella and Tristan Gradetzke — TU Dortmund University

The Cherenkov Telescope Array Observatory (CTAO) is the next generation high energy gamma ray observatory. It reaches higher sensitivities than current instruments, between several GeV to hundreds of TeV by facilitating different types of telescopes in the array, which differ mainly in their size. The LST-1 is the first prototype of a Large Sized Telescope of the array, sensitive to the lower energies. It is currently finishing commissioning at the CTAO-North array site, located at the Roque de los Muchachos Observarory (ORM) on La Palma.

As Imaging Air Cherenkov Telescope (IACT) measurement time is limited by dark hours, maintenance is essential to ensure smooth operation and maximize the uptime. In order to find problems in structural dynamics of the telescope, condition monitoring and predictive maintenance can be performed using sensors placed across the structure. In the years since start of operations, different kinds of sensors have been installed, including linear displacement sensors, vibration sensors and so-called load pins. Methods of data acquisition and a preliminary analysis of recent data from these sensors is presented.
