Scientists from around the globe are working at the CERN research center in Switzerland, home to the world’s most powerful particle accelerator – the Large Hadron Collider (LHC). Around 50 physicists from TU Dortmund University are participating in two large-scale projects at the LHC and contributing to the parallel development of theoretical models. As of July, their work is being funded by the Federal Ministry of Education and Research (BMBF) with a further € 4.3 million for three years as part of ErUM-Pro project funding.
At CERN, international scientists are searching for particles to date unknown. In order to solve physics questions so far unanswered, they are also studying properties and interactions of already known elementary particles. In a ring-shaped underground tunnel about 27 kilometers long, packets of protons are accelerated to almost the speed of light and made to collide. Billions of elementary particles are created in the process. Gigantic detectors record their tracks, their energy, and their decay.
Physicists from TU Dortmund University are involved in work on two detectors: The teams led by Professor Johannes Albrecht and Professor Bernhard Spaan are conducting research on the Large Hadron Collider beauty experiment (LHCb). The focus here lies on precision measurements and the search for rare decays. The group led by Professor Kevin Kröninger is contributing to the ATLAS experiment. This is concerned with the search for so far unknown forces and elementary particles. Theoretical studies of the processes taking place in the particle accelerator are the responsibility of the working group led by Professor Gudrun Hiller. To interpret the data, theoretical models and analyses are required.
New LHCb detector
The work of the experimental particle physicists and TU Dortmund University necessitates regular on-site presence at CERN. These visits are funded by the Federal Ministry of Education and Research, among others. The ministry’s funding is, however, indispensable above all for the maintenance and operation as well as the upgrading and further development of the detectors. The LHC has been modified and overhauled in recent years, so that the accelerated protons now collide more violently than ever before. To be able to make the best possible use of the functionalities of the redesigned particle accelerator, the detectors also need to be upgraded. “We’re currently installing a new LHCb detector and have made an important contribution to the construction of the tracking detector in the framework of the funding provided by the Federal Ministry of Education and Research,” says Professor Johannes Albrecht. The LHCb upgrade is scheduled to go into operation in the spring of 2022. The next step will be to upgrade the ATLAS experiment. Here too, the scientists will benefit from the ministry’s funding.

Location & approach
The campus of TU Dortmund University is located close to interstate junction Dortmund West, where the Sauerlandlinie A 45 (Frankfurt-Dortmund) crosses the Ruhrschnellweg B 1 / A 40. The best interstate exit to take from A 45 is “Dortmund-Eichlinghofen” (closer to South Campus), and from B 1 / A 40 “Dortmund-Dorstfeld” (closer to North Campus). Signs for the university are located at both exits. Also, there is a new exit before you pass over the B 1-bridge leading into Dortmund.
To get from North Campus to South Campus by car, there is the connection via Vogelpothsweg/Baroper Straße. We recommend you leave your car on one of the parking lots at North Campus and use the H-Bahn (suspended monorail system), which conveniently connects the two campuses.
TU Dortmund University has its own train station (“Dortmund Universität”). From there, suburban trains (S-Bahn) leave for Dortmund main station (“Dortmund Hauptbahnhof”) and Düsseldorf main station via the “Düsseldorf Airport Train Station” (take S-Bahn number 1, which leaves every 15 or 30 minutes). The university is easily reached from Bochum, Essen, Mülheim an der Ruhr and Duisburg.
You can also take the bus or subway train from Dortmund city to the university: From Dortmund main station, you can take any train bound for the Station “Stadtgarten”, usually lines U41, U45, U 47 and U49. At “Stadtgarten” you switch trains and get on line U42 towards “Hombruch”. Look out for the Station “An der Palmweide”. From the bus stop just across the road, busses bound for TU Dortmund University leave every ten minutes (445, 447 and 462). Another option is to take the subway routes U41, U45, U47 and U49 from Dortmund main station to the stop “Dortmund Kampstraße”. From there, take U43 or U44 to the stop “Dortmund Wittener Straße”. Switch to bus line 447 and get off at “Dortmund Universität S”.
The AirportExpress is a fast and convenient means of transport from Dortmund Airport (DTM) to Dortmund Central Station, taking you there in little more than 20 minutes. From Dortmund Central Station, you can continue to the university campus by interurban railway (S-Bahn). A larger range of international flight connections is offered at Düsseldorf Airport (DUS), which is about 60 kilometres away and can be directly reached by S-Bahn from the university station.
The H-Bahn is one of the hallmarks of TU Dortmund University. There are two stations on North Campus. One (“Dortmund Universität S”) is directly located at the suburban train stop, which connects the university directly with the city of Dortmund and the rest of the Ruhr Area. Also from this station, there are connections to the “Technologiepark” and (via South Campus) Eichlinghofen. The other station is located at the dining hall at North Campus and offers a direct connection to South Campus every five minutes.
The facilities of TU Dortmund University are spread over two campuses, the larger Campus North and the smaller Campus South. Additionally, some areas of the university are located in the adjacent “Technologiepark”.
