Research Activities of the Institute for Nuclear Physics (IKP)

The Institute for Nuclear Physics is engaged in fundamental research in the fields of particle- and astrophysics in cooperation with international research institutions. Current projects are the air shower simulation CORSIKA, the direct dark matter search experiment EDELWEISS, the neutrino mass experiment KATRIN, and the air shower experiments at the Pierre Auger Observatory and Tunka-Rex. Since 2015 there is also a group on the subject of astroparticle theory.

 

The KATRIN Experiment at KIT, Campus North

KATRIN intends to determine directly the mass of the electron neutrino or set a new upper limit as low as 0.2 eV/c2 by measuring precisely the shape of the β spectrum from tritium decay near the endpoint. The current upper llimit is 2.3 eV/c2 KATRIN is currently being built at the Karlsruhe Tritium Laboratory by an international collaboration including four KIT institutes. IK is responsible for the spectrometers und takes part in several other tasks in KATRIN.

The Pierre Auger Observatory in Argentina

At the world’s largest air shower experiment, the Pierre-Auger-Observatorium IKP is involved in designing and building the fluorescence telescopes and the electronics for data taking and triggering. The telescopes detect showers of the highest energies directly by their fluorescense radiation. The muon component is measured at ground level by 1600 water-filled detector tanks distributed over the whole Auger site of about 3000 km2.

Das IceCube Observatory at the South Pole

IceCube is the neutrino observatory located at the South Pole consisting of optical modules within a cubic kilometer of Antarctic ice. Neutrinos, as almost elusive particles, are great cosmic messengers possibly pointing to the extreme astrophysical sources and giving insight to processes involved in creating highest energy particles. Our group at KIT is mainly working in the frame of the next generation of the IceCube experiment, IceCube-Gen2.

Theoretical Astroparticle Physics

Astroparticle Theory

Astroparticle physics is the union of elementary particle physics with cosmology and astrophysics. We search for new fundamental physics and try to understand our Universe by investigating the interplay of physics at the very smallest and very largest length scales. The group  Theoretical Astroparticle Physics at IKP considers various aspects of neutrino physics as well as the problem of Dark Matter in the Universe. We work mostly on the phenomenology of theoretical models and the interpretation of data.

 

Theoretical Particle Physics

Particle Theory

The group Theoretical Particle Physics at IKP is engaged with various aspects of particle physics both in and beyond the Standard Model. In our research, we investigate models of New Physics and their phenomenology in the fields of collider physics, Higgs physics, flavour physics, and Dark Matter. In addition we perform precision calculations for predictions of the Standard Model which are necessary to unambiguoulsy identify even small deviations from the Standard Model.

 

The EDELWEISS Experiment in France

The EDELWEISS experiment located in the Modane underground laboratory in France is searching for Cold Dark Matter particles in the Universe, so-called WIMPs. In its third phase equipped with up to 40 Germanium bolometers operated at 20mK, EDELWEISS is focussing on low mass WIMPs. The IKP is responsible for the100m2 surface muon veto counter system. Together with IPE and ETP, the KIT group is also involved in the digital readout electronics, signal modelling and data analysis.

 

FUNK – Search for hidden-­photon dark matter

The FUNK Experiment searches for dark matter in the hidden-photon sector using a large spherical mirror with an area of more than 14 m2, probing for dark matter candidates with masses in the eV and sub-eV energy range. FUNK is located at the KIT and re-uses mirror segments developed for the Pierre Auger Observatory.

 

The Tunka Radio Extension (Tunka-Rex) in Sibira

Tunka-Rex is an array of radio antennas at the Tunka observatory in Siberia close to Lake Baikal. The primary goal of Tunka-Rex is the further development of the radio technique for the measurement of high-energy cosmic rays. Therefore, we perform a cross-calibration to the established Cherenkov-light technique. The IKP holds the leading role in Tunka-Rex, which is one of two projects within a Helmholtz Russian Joint Research Group.

 

Air Shower Simulations with CORSIKA

Corsica

CORSIKA is a detailed Monte Carlo program to study the evolution and properties of extensive air showers in the atmosphere. While CORSIKA was originally designed in 1989 for the KASCADE experiment it developed to THE standard simulation tool for all experiments dealing with extensive air showers induced by energetic cosmic rays, gamma rays or neutrinos.

 

KASCADE Cosmic-Ray Data Centre (KCDC)

Corsica

KCDC is a web platform for distributing air-shower events measured by the KASCADE and KASCADE-Grande experiments. KCDC provides access to more than 430 million events measured by the KASCADE /KASCADE-Grande arrays and the Central Detector. Each event data set consists of 24 observables including both, reconstructed shower properties, like the number of charged particles at ground, and meta data, like event time, as well as data arrays like energy deposits and arrival times for every single detector station.
