    Abstract : With the advent of increasingly advanced spectroscopic instruments after the turn of the century, it has become accessible to unravel the structure of instantly ‘vanishing’ nuclei, with lifetimes as short as 1 μs, and responsible for pile-up events in analog electronics. Experimental data has been recorded by the Nuclear Structure Group at Lund University for 48Ca/50Ti + nat. READ MORE

  3. 2. Dead layer determination for the new implantation detector of the LUNDIUM decay station

    University essay from Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Eleftheria Kosta; [2022]
    Keywords : Physics and Astronomy;

    Abstract : The Nuclear Structure Group in Lund, focuses on nuclear spectroscopy of decays of rare isotopes. A new decay station, called LUNDIUM, is currently being built, which will involve silicon and germanium detectors for the study of these nuclei. This thesis focuses on the characterization of one of the new silicon detectors, the implantation one. READ MORE

  4. 3. Simulation of Anti-Compton Shield Augmentation to the Lundium Decay Station Using Geant4

    University essay from Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Daesung Cho; [2019]
    Keywords : Lundium; Geant4; Anti-Compton shield; gamma spectroscopy; Physics and Astronomy;

    Abstract : The Lundium decay station improves on the existing TASISpec spectrometer used to investigate the nuclear structure of superheavy nuclei by photon- and charged particle-spectroscopy. This thesis aims to explore the potential benefits of the future Lundium station with the augmentation of anti-Compton shields com- posed by a set of BGO scintillator bars. READ MORE

  5. 4. Extraction of energy and time from pile-up pulses with fast sampling ADC analysis techniques

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Kärnfysik

    Author : Anton Roth; [2016]
    Keywords : moving window deconvolution; alpha-decay; short-lived nuclei; digital pulse processing; Superheavy elements; decay paths; Physics and Astronomy;

    Abstract : Debates of whether Z=114 and N=184 are the next magic numbers in nuclear physics have existed since the earliest predictions made in the 1960s. Until these days they have not been firmly established. READ MORE
