Kleines Radioteleskop 3.0 m (KRT3)

KRT3  Hauptgebäude The KRT3 is a radio telescope, which became operational at Hamburger Sternwarte in autumn  2019. The instrument is equipped with a parabolic dish of 3 m diameter and with a digital receiver for a wavelength of 21 cm (1420 MHz). With the KRT3 instrument the continuum of bright radio sources and the 21cm line of atomic hydrogen can be observed.
The telescope is a  SPIDER 300A model purchased from the company Primaluce Lab / Italy. It replaces the former KRT3 radio telescope from CASSI Corp. (USA), which was in operation since 2011.
KRT3 is used at the Sternwarte as lab exercise for the Praktikum für Fortgeschrittene (PHY-FP), a module of the physics curriculum, for Schüler/innen-Ferienkurse addressing high-school students from the Metropolregion Hamburg, and for public outreach, as on Open Days or the Long Night of the Sciences.
