LST Condition Monitor — •Felix Pfeifle, Karl Mannheim, and Marcel Vorbrugg for the CTA collaboration — Lehrstuhl für Astronomie, Universität Würzburg

The Large-Sized Telescope (LST) with a mirror diameter of 23 m is the largest of the telescope designs for the Cherenkov Telescope Array (CTA). While LST-1 is finishing commissioning, LST 2-4 are currently under construction for a timely completion of the full LST subarray in the Roque de los Muchachos Observatory (ORM) in La Palma.

The LSTs will be exposed to rapid pointing maneuvers during follow-up observations of gamma-ray bursts and gravitational wave events. The piezo-electrical acceleration sensors have been mounted on LST1 bogies, delivering data on mechanical accelerations used as a diagnostic tool to predict the bogies' health and safety. We analyzed data from the sensors searching for eigenfrequencies to set thresholds alerting in case of pathological responses. We outline the plan to implement a condition monitor system for the predictive maintenance of the LSTs and present preliminary results of our analyses.

Keywords: LST; condition monitor; CTA; predicitive maintenance
