Supervisor’s research interests:
TThe LEGEND experiment is designed to search for neutrino less double beta (0vββ) decay of 76Ge. LEGEND will operate with bare germanium semiconductor detectors (enriched in Ge-76) directly immersed in liquid argon instrumented to readout argon scintillations for vetoing background events. Thanks to these approach in the predecessor GERDA experiment the background level was reduced down to the unprecedented value of 10-3 counts keV‑1 kg-1 yr-1. In order to further reduce any background interruptions in LEGEND experiment, the R&D for novel germanium detector types, new ultra-low background construction materials and the effective methods of argon scintillation readout is being constantly performed by our JINR group together with our international collaborators. Our group has solid experience achieved at the design, preparation and integration phases of the GERDA experiment as well as during operating of the experiment and the analysis of data. This will help the JINR group to keep the strong position in the LEGEND project. However, we are willing to enlarge the analysis part of our group – so we are looking for the candidate who will work mainly for the modelling and data analysis. Research highlights: LEGEND is truly world-wide collaboration includes about 240 scientists fr om 47 institutions. The especially good connection our group has with The Technical University of Munich (Germany) and Max Planck Institute for Nuclear Physics, Heidelberg (Germany), so some working visits there are expected as well as to Gran Sasso National Laboratory in Italy, wh ere the first phase of LEGEND will take place. The successful candidate is expected to join the international LEGEND data analysis team.
Supervisor’s specific requirements:
Main publications:
- Master’s degree / equivalent in a related field
- B2 level of English
- Good track record of publications related to the topic of the intended research
- Strong research proposal 1,500 - 3,500 words
