Location & approach

By car

The campus of the Technical University of Dortmund is located near the freeway junction Dortmund West, where the Sauerland line A45 crosses the Ruhr expressway B1/A40. The Dortmund-Eichlinghofen exit on the A45 leads to the South Campus, the Dortmund-Dorstfeld exit on the A40 leads to the North Campus. The university is signposted at both exits.

By bus and train

The "Dortmund Universität" S-Bahn station is located directly on the North Campus. From there, the S-Bahn line S1 runs every 20 or 30 minutes to Dortmund main station and in the opposite direction to Düsseldorf main station via Bochum, Essen and Duisburg. In addition, the university can be reached by bus lines 445, 447 and 462. Timetable information can be found on the homepage of the Rhine-Ruhr transport association, and DSW21 also offer an interactive route network map.

The H-Bahn

One of the landmarks of the TU Dortmund is the H-Bahn. Line 1 runs every 10 minutes between Dortmund Eichlinghofen and the Technology Center via Campus South and Dortmund University S, while Line 2 commutes every 5 minutes between Campus North and Campus South. It covers this distance in two minutes.

By plane

From Dortmund Airport, it takes just over 20 minutes to get to Dortmund Central Station by AirportExpress and from there to the university by S-Bahn. A wider range of international flight connections is offered by Düsseldorf Airport, about 60 kilometers away, which can be reached directly by S-Bahn from the university's train station.

Particles Colloquium: Particle accelerators in the sky - The physics of Terrestrial Gamma-ray Flashes

Begin: 10/19/2023, 4:00 PM End: 10/19/2023, 5:00 PM Location: Seminar room CP-03-123

On 19.10, Dr. Christoph Köhn will speak on the topic "Particle accelerators in the sky - The physics of Terrestrial Gamma-ray Flashes".

Abstract:
Lightning is a multiscale phenomenon bridging several length scales, from the nanoscale motion of electrons to the kilometer long lightning channels, and multitudinous energy scales ranging from sub-eV to several tens of MeV. In this presentation, I am going to give an introduction into the physics of electric discharges as well as of production and properties of terrestrial gamma-ray flashes (TGFs), bursts of energetic photons emitted from thunderstorms with quantum energies of up to 40 MeV, making them the highest natural phenomena from Earth with energies beyond those of radioactive decay chains. They are created through the Bremsstrahlung process when relativistic electrons collide with air molecules; however, we miss details on their production as well as of their effects in our atmosphere. I will give an overview of the research in my group including the numerical modelling of discharges and TGFs. We are currently looking into how electrons can reach relativistic electrons in the electric fields relevant for lighting discharges, how TGFs might trigger the production of greenhouse gases as well as how TGFs were produced in the atmosphere of Primordial Earth and how they might have affected the production of amino and carbon acids as a precursor of life.
In the very end, I will elaborate on future ideas (including current grant proposals) and of some of my side activities and collaborations associated to the modelling of astrophysical plasmas, theory and modelling in curved space-time and the modelling of discharge phenomena in exoplanet atmospheres. Finally, I will give possible links to the research activity at the TU Dortmund University.
