Description
With its 1km3 in-ice sensor array complemented by a 1km2 surface array of ice-Cherenkov tanks for particle detection, the IceCube observatory is not only the largest neutrino telescope but also one of the world's most competitive instrument for studying cosmic rays in the PeV to EeV regime. In particular, studying high-energy muons from
the shower core in coincidence with particle flux on the surface yields a handle on cosmic ray composition in the energy range where the transition from galactic to extra-galactic sources should occur.
Further augmenting the IceCube observatory with an array of radio sensor in the 10-100MHz regime will additionally allow for observation of the geomagnetic radio emission from the air shower. Reflecting the whole shower development, this radio signal will not only provide for significantly reducing the systematic errors involved with the sampling approaches, but will also result in an additional, independent handle on the shower maximum. Such a triple-technology array should therefore significantly improve the understanding of cosmic rays.
I will present first results from exploratory instrumentation deployed at the SouthPole, indicating its suitability for this approach. In addition, first performance studies using a detailed MonteCarlo simulation including IceCube/IceTop and the radio array will be shown, and prospects for the installation of a test array will be discussed.
