The RT4 radio telescope with a diameter of 32 meters, the most important instrument at the Astronomical Observatory of the Nicolaus Copernicus University in Piwnice near Toruń and the largest antenna of this type in Poland, has undergone a thorough renovation.
After almost 25 years of uninterrupted operation, the radio telescope has undergone renovation. Numerous corrosion flaws were removed from the antenna surface, then the entire instrument was re-painted, and special attention was paid to the appropriate protection of the reflecting surfaces of the main and secondary mirrors.
Defects in the foundations of the radio telescope track were supplemented, and the base of the lift used for servicing at the antenna’s secondary mirror was repaired. Additionally, during renovation works, the signal cables between the antenna and the building in which the radio telescope control room is located were replaced. The engineers also modernized the computer and internet infrastructure.
