Description

The Radar Echo Telescope (RET) is a proposed next-generation ultrahigh energy (UHE) neutrino detector. A prototype instrument, recently deployed to the polar regions, uses the in-ice cascade from a UHE cosmic ray as a proxy for a UHE neutrino, to test the detection technique in nature. This prototype, called the Radar Echo Telescope for Cosmic Rays (RET-CR), collected a full season of data in the summer of 2024. We will discuss this instrument, the detection technique, and some preliminary results from the ongoing analysis of the data.
