• 30.03.2019 Young employees and students of the department 67 took part in the data collection session at the HADES experiment
    The HADES data set session is part of the FAIR PHASE-0 program in preparation for the launch of the SIS-100 accelerator planned for 2025, which will run a whole range of experiments, one of which is the CBM (Compressed Baryonic Matter). The bachelor of the Department of Condensed Matter Physics Mikhail Mamaev and Associate Professor Ilya Selyuzhenkov took part in the data set. This year, the experiment recorded Ag + Ag collisions at an energy of 1.65 GeV per nucleon of the incident nucleus. The session was the most successful in the history of HADES - more than 15 billion events were gathered. The data obtained will make it possible to supplement the earlier measurements for heavier (Au + Au) and lighter (C + C, Ar + KCl) systems, as well as for proton-nuclear and proton-proton collisions. As part of the FAIR PHASE-0 program at HADES, one of the components of the future CBM experiment at FAIR - the Cherenkov radiation detector (RICH) was successfully tested and implemented. In connection with stopping the SPS accelerator and the LHC collider at CERN to improve their performance, the SIS18 accelerator at the FAIR for the next few years remains the only functioning heavy ion accelerator in Europe. HADES provides an opportunity for students and graduate students of the National Research Nuclear University MEPhI to continue to gain experience in accelerator complexes. For example, the results obtained from the analysis of HADES data will be the basis of Mikhail Mamaev’s bachelor’s thesis, which he will have to defend this year. In addition to direct work on the experiment, the staff of the NRNU MEPhI took part in the regular meeting of the HADES collaboration, held in Darmstadt from 11 to 15 March. The meeting discussed the status of studies conducted on the basis of already collected data, addressed issues related to the current session, and planned further development of the experiment. In addition to HADES, the NIIU MEPhI group for the study of heavy ion collisions works in the existing experiments NA61 / SHINE (accelerator SPS, CERN, Switzerland), STAR (collider RHIC, BNL, USA), BM @ N (Nuklotron, JINR, Russia), as well as participates in the development of future CBM experiments (accelerator SIS100, FAIR, Germany) and MPD (NICA, JINR, Russia). The group is actively engaged in the physical analysis of existing data and the preparation of processing packages for new ones.
