Description

The Radar Echo Telescope for Cosmic Rays (RET-CR) is a prototype experiment for the future neutrino detector, the Radar Echo Telescope for Neutrinos (RET-N). It is deployed at Summit Station in Greenland, with a full data-taking run conducted in the summer of 2024.

This experiment utilises the radar technique to search for an in-ice secondary cascade produced when the core of a high-energy cosmic ray air shower propagates into the high-altitude ice sheet.

RET-CR, along with the in-ice radar system, includes five surface stations, each equipped with IceTop scintillator panels and a SKALA radio antenna. These surface stations trigger on incoming cosmic ray air showers and independently reconstruct the arrival direction, primary energy, and core position. The radar search for secondary in-ice cascades and the properties obtained will be validated against the measurements from the surface stations.

This contribution focuses on the air shower reconstruction of cosmic ray parameters using the particle data.
