ERC Starting Grant - Digital Radio Detectors for Galactic PeV Particles
Prototype station of the surface array at the South Pole.
Installation of a prototype antenna in 2019.

IceTop, the cosmic-ray surface array of the IceCube Neutrino Observatory, is forseen to be enhanced to increase its accuracy and aperture. As part of this project, radio antennas shall be installed in addition to a planned upgrade with scintillation detectors. By adding the radio antennas, the accuracy will be further improved and the sky coverage increased such that the Galactic Center will be in the field of view. Using an optimized frequency band for the radio detection of atmospheric particle cascades (air showers), we expect to significantly lower the threshold of the radio technique for cosmic particles down to the PeV range. This will enable the search for PeV photons from the Galactic Center as an exciting science case next to better measurements of the mass composition of Galactic Cosmic Rays. This progress in instrumentation aims at understanding the yet unknown origin of the most energetic particles in our Galaxy. Depending on what these undiscovered sources are, we will have a chance to reveal the most powerful natural accelerator in our Milky Way.

The work of this project is done in collaboration with the IceCube group at the institute which has a leading involvement in the upgrade of the surface array by scintillators. As first step towards the realization of the radio enhancement, two antennas of the SKALA type developed for the Square Kilometer Array (SKA) were installed at the South Pole at the existing prototype station for the scintillator upgrade early 2019 (see photo).
