IceCube South Pole Neutrino Observatory
IceCube is a neutrino observatory located at the South Pole consisting of optical modules within a cubic kilometer of Antarctic ice. Neutrinos, being elusive particles, are cosmic messengers that can point to the highly energetic astrophysical sources in the Universe and gives insight to the processes involved in creating the highest energy particles in these sources. The surface part of IceCube, IceTop: including 162 ice Cherenkov tanks, enables the study of cosmic-ray air-showers and acts as a veto for the astrophysical events observed by the in-ice detectors.
Our group at KIT is mainly working on the enhancement of the IceCube experiment. Our working areas are
- Design and preparation of the new surface array
- Search for high-energy gamma rays
- Elemental composition studies of Cosmic Rays
- Validation of hadronic interaction models
- Study of the muon content and distributions in air showers
The main idea of the IceTop enhancement is to build a hybrid surface array consisting of scintillator panels and radio antennas in order to improve the measurements of air showers. In this field, we are active in all the stages: detector development, construction, deployment and operation as well as simulation studies for the future surface array.
Apart from this, our group is also involved in the IceCube Upgrade. The upgrade involves the deployment of new sensors within the infill array of IceCube, which will greatly enhance the accuracy of detection of the lowest energy neutrinos. The IceCube Upgrade is already underway and is expected to be completed by 2023.
