On the morning of Nov. 13, 2022, with the last antenna in place, the Daocheng Solar Radio Telescope (DSRT) project completed system integration and entered the commissioning phase.
The project is expected to be completed in June 2023 and enter the commissioning phase for full scientific research.
The DSRT project, with an investment of about 100 million RMB, consists of 313 antennas with a diameter of 6 meters.
These antennas are evenly distributed on a 1 km diameter circle, and a 100 m high calibration tower at the center of the circle provides the calibration reference for the whole observation link.
The telescope operates in the radio frequency band of 150 MHz-450 MHz and can image the solar outburst activity into a spectrum of observations.
When fully completed, the circular array solar radio imaging telescope will be able to monitor solar radio flares in real time and
It can follow the entire process of coronal mass ejection (CME) formation, evolution, and entry into the interplanetary space.
It plays an important role in exploring the dynamic features and variation patterns of the solar-terrestrial space environment with high spatial and temporal resolution.
It will also play an important role in the field of night astronomy research such as pulsar search and space science popularization. (National Space Science Center, Chinese Academy of Sciences)
