Description

Recently the radar scattering technique to probe neutrino induced particle cascades in ice was investigated. The feasibility of this method was shown to crucially depend on several up to now unknown plasma properties, such as the plasma lifetime and the free charge collision rate. These parameters can be combined in an efficiency parameter for the radar scattering cross-section. We report on experimental results obtained for the radar scattering cross-section in ice. This experiment is performed at the Telescope Array Electron Light Source facility, where a beam of high-energy electrons was directed in a block of ice. The induced ionization plasma was consequently probed using a radar detection set-up detecting over a wide frequency range from 200 MHz up to 2 GHz.
