CBM
CBM is the future experiment with which we aim to study the QCD phase diagram at moderate temperatures but very high baryon densities. The compressed nuclear matter to be characterized will be produced in heavy-ion collisions, e.g., gold-gold collisions, at beam energies of 4 to 15 GeV per nucleon at the future FAIR accelerator facility.
The subdetectors of the CBM experiment are designed to allow the investigation of hadronic, leptonic, and photonic samples of the quark-gluon plasma. With the CBM experiment, we are entering a new era in the study of diagnostic samples of the QGP, as the planned measurements in this energy range were previously not possible but offer unique research potential in the field of heavy-ion physics.
Our research group is currently engaged in the design and construction of the CBM RICH detector in collaboration with other universities and institutes. The RICH detector will consist of an 11.8-square-meter mirror wall that reflects the generated Cherenkov radiation onto a photodetector. The Cherenkov radiation is generated within the gas volume of the RICH detector. Members of our research group are currently working on the design and fabrication of the mirror mount, measurement and control methods for positioning the mirrors, and measurements of the reflectivity of the individual mirrors, as well as developing a design for the gas control unit, which is currently being tested as a prototype in our laboratory. In addition to this work, we are also preparing the software for reconstructing the RICH data and analyzing the generated dielectrons.
