    Characterization of 30 Ge-76 enriched Broad Energy Ge detectors for GERDA Phase II
    (2019) Agostini, M.; Bakalyarov, A. M.; Andreotti, E.; Balata, M.; Belogurov, S.; Белогуров, Сергей Геннадьевич
    The GERmanium Detector Array (Gerda) is a low background experiment located at the Laboratori Nazionali del Gran Sasso in Italy, which searches for neutrinoless double-beta decay of 76Se+2e-. Gerda has been conceived in two phases. Phase II, which started in December 2015, features several novelties including 30 new Ge-76 enriched detectors. These were manufactured according to the Broad Energy Germanium (BEGe) detector design that has a better background discrimination capability and energy resolution compared to formerly widely-used types. Prior to their installation, the new BEGe detectors were mounted in vacuum cryostats and characterized in detail in the Hades underground laboratory in Belgium. This paper describes the properties and the overall performance of these detectors during operation in vacuum. The characterization campaign provided not only direct input for Gerda Phase II data collection and analyses, but also allowed to study detector phenomena, detector correlations as well as to test the accuracy of pulse shape simulation codes.

    The First Experiments with the New ACCULINNA-2 Fragment Separator
    (2019) Fomichev, A. S.; Bezbakh, A. A.; Wolski, R.; Gazeeva, E. M.; Belogurov, S. G.; Grigorenko, L. V.; Белогуров, Сергей Геннадьевич; Григоренко, Леонид Валентинович
    © 2019, Allerton Press, Inc.Abstract: Characteristics of a new separator of radioactive ion beams (RIBs) are described. It was recently commissioned at the Flerov Laboratory of Nuclear Reactions (FLNR JINR) and is in operation at the primary beam line of the U-400M heavy ion cyclotron providing RIBs in energy range of 10–50 MeV/nucleon. Preliminary results obtained in the first experiments performed with this separator in 2018 are presented. A medium-term program of scientific research is discussed.
