AG Brinkmann


Kai-Thomas Brinkmann


The Brinkmann working group is active in the field of experimental hadron physics with a focus on detector physics (tracking detectors, calorimeters) and is involved in the experiments PANDA, Crystal Barrel/TAPS and CLAS, and to a lesser extent A2@MAMI and HADES.
Other areas of work include the analysis of the data obtained in the above-mentioned experiments with regard to fundamental physical questions, investigations into the radiation hardness of electronics for space applications, as well as the design and development of detectors and characterization of detector materials, including for medical diagnostics and therapy.
For activities related to the PANDA experiment, AG Brinkmann receives financial support from the Federal Ministry of Education and Research as part of the ErUM-FSP T08 research priority, while investigations into new detector materials are funded as part of the EU INTELUM project.

Netzwerk Teilchenwelt Masterclass at the Weidigschule Butzbach

On February 14, a total of 30 pupils at the Weidigschule Butzbach had the opportunity to gain an insight into particle physics. As part of the "Netzwerk Teilchenwelt", the two employees of AG Brinkmann - Kim Tabea Giebenhain and Lara Dippel - offered a masterclass on the ATLAS detector and Higgs boson, in which pupils from six different schools in the MINT-EC Excellence Network (Weidigschule Butzbach, Liebig-Schule Gießen, Goetheschule Wetzlar, Martin-Luther-Schule Marburg, Johanneum Gymnasium Herbon, Philippinum Gymnasium Weilburg) were able to build their own cloud chambers after an introductory lecture on the standard model, particle accelerators and detector physics and tried their hand at analyzing LHC data with the help of the "Hypathia" software.

DPG Spring Meeting in Gießen

This year's spring conference of the German Physical Society (DPG) of the sections "Hadrons and Nuclei" and "Gravitation and Relativity" will take place at Justus Liebig University from March 11 to 15. The main focus here is on the transfer of knowledge and the promotion of young scientists. Due to the comprehensive inclusion of contributions in the conference program, the spring conference also offers Bachelor's and Master's students the opportunity to discuss their work. More information on registration and the program can be found on the conference website.

University Information Days 2024

On February 24 and 25, the University Information Days were once again held at Justus Liebig University and elsewhere. Pupils had the opportunity to find out more about the different courses of study the JLU and THM offer. In addition to general information on the wide range of degree courses, those interested in physics also had the opportunity to take part in laboratory tours of various working groups. Furthermore, in an experimental physics lecture by Prof. Brinkmann, several experiments were demonstrated that potential future physics students will encounter again in their first semesters.

Stratospheric Balloon Start on 19.11.2022

On Saturday, November 19, 2022, a team from the II Institute of Physics at JLU Giessen successfully launched a stratospheric balloon with various scientific and didactic experiments on board. The probe, named "STRATO-II", was launched on the "Natural Sciences" campus at 11:36 local time in the presence of around 30 people (helpers, onlookers and interested parties). During the entire flight time of 3.5 hours, telemetry data was received via several communication bands. The balloon ascended to a maximum altitude of 34800m before its envelope burst under the low ambient pressure in the stratosphere of only 6 mBar and the payload with the experiments fell back to earth. The landing, which was predicted to be near Coburg in Franconia, actually took place a little further east at the "border triangle" between Bavaria, Thuringia and Saxony. A GPS tracker flying with the aircraft finally communicated the landing coordinates via a mobile internet connection, so that the next day a radio amateur living in the area was able to collect the payload in the form of a polystyrene capsule and thankfully send it back to Giessen. The callsign DN5FCG required for the flight permit was kindly provided to us by W. Senger, a former employee of JLU.This callsign can be used to trace the probe's flight path on typical probe trackers such as
Among other things, a profile of the cosmic radiation in the different atmospheric layers could be determined from the measurement data transmitted by the probe and written to a memory card.
A video of the entire flight with live telemetry data is available here.
