[CRI229] Cosmic ray mass composition with LOFAR


  • Stijn BUITINK

Primary authors


The LOFAR radio telescope measures the radio emission from extended air showers with unprecedented precision. In the dense core individual air showers are detected by hundreds of dipole antennas. By fitting the complicated radiation pattern to Monte Carlo radio simulation codes we obtain measurements of Xmax with a precision of <20 g/cm^2. We present the latest LOFAR results of cosmic-ray mass composition analysis in the energy regime of 10^17 eV to 10^18 eV and discuss the systematic uncertainties introduced by factors such as hadronic interaction models and the desciption of the atmopshere.
