Research Abstract

We are carrying out an R&D project to search for radar echoes from cosmic ray induced extensive air showers. To test and develop this technique, we have used the Electron Light Source (ELS) electron beams at the Telescope Array site as artificial air showers. A radio transmitter and receivers have been constructed and placed them140m from the accelerator beam to search for radar echoes from the trail of the electron beam. In September and December 2012, we have tried to detect radio signals from ELS electron beams of 40MeV, 109 electrons with two different beam durations. We have not found any radio echo signals, but we have observed a radio emission from the electron beam.
