Two New 30-meter Telescopes for Observing Interplanetary Scintillation

The solar wind is a high-speed stream of charged particles originating from the solar corona and continuously radiating outward. Investigating the formation mechanisms of the solar wind and its propagation and impact in interplanetary space provides crucial support for both space science research and space engineering. The newly constructed Interplanetary Scintillation Telescope under the Meridian Project II aims to monitor the propagation of background solar wind and solar storm disturbances in interplanetary space. This telescope system adopts an observation mode of one main station and two sub stations, with the sub stations equipped with two 30-meter parabolic telescopes. This paper primarily focuses on the development and performance of the 30-meter telescope.
