  1. 1. The Commissioning of a Pixelated Charge-particle Detector : for High-sensitivity Measurements of Hydrogen

    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : Joacim Stenlund; Aram Himelius; [2023]
    Keywords : ;

    Abstract : The Tandem Laboratory at Uppsala University, a national research infrastructure forworld-leading materials analysis, has a long history of performing hydrogen measurementusing NRA (Nuclear Reaction Analysis). This project intents to diversify the infras-tructure for hydrogen measurement by investigating the feasibility of an advanced ERCS(Elastic Recoil Coincidence Scattering) system, enabling finer detection limits.

  3. 2. Generation and Characterization of Intense Attosecond Pulses

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

    Author : Marius Plach; [2020]
    Keywords : Attosecond physics; high-order harmonic generation; high harmonic generation; HHG; attosecond pulses; molecular dynamics; attosecond pulse generation; harmonic emission time delay; temporal reconstruction of attosecond pulses; strong field processes; Three-step model; RABBIT; Reconstruction of Attosecond Beating By Interference of Two-photon Transition; Terawatt Laser System; Intense XUV Beamline; XUV; LLC; Physics and Astronomy;

    Abstract : Research on ultrafast dynamics in atoms and molecules requires short pulses. In order to resolve processes taking place on a femtosecond timescale sufficiently, these pulses require a duration on the attosecond time scale. READ MORE

  4. 3. Measurement of particle yields induced by 200-MeV protons on multiple targets

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

    Author : Rafael Antonio Lopez; [2018]
    Keywords : QFS; Quasi-free Scattering; 16O; 112Sn; 124Sn; FAIR; CsI Tl ; R3B; 6.3-MeV gamma; CALIFA; p; 2p ; Physics and Astronomy;

    Abstract : One way to probe the structure of atomic nuclei far from stability is via quasi-free scattering (QFS) reactions. We conducted a (p,2p) QFS experiment on H2O, 112Sn, 124Sn and 208Pb targets in order to test the performance of CsI(Tl) detectors that are to be used in the upcoming R3B experiments at FAIR.

  5. 4. Trace element analysis based on neutron activation with coincident gamma ray detection

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

    Author : Jessica Delgado; [2017]
    Keywords : scintillator detectors; gamma ray; gamma radiation; spectrometer; neutron activation analysis; trace element; Physics and Astronomy;

    Abstract : In this work, six soil samples have been analyzed. The samples come from different sedimentary layers on Earth. They were previously studied with the objective to find the trace concentration of iridium, to correlate the increased concentrations of iridium with meteorite impacts that have occurred on Earth.

  6. 5. The Characteristics of B4C Coated Scintillators

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

    Author : Anton Bodahl; [2016]
    Keywords : B4C; Scintillators; Coincidence Measurements; LIBAF; Homogenity Measurements; Physics and Astronomy;

    Abstract : The characteristics of Boron Carbide (B4C) coated polyvinyltoluene scintillators with a sputtered B4C coating ranging between 200 and 1000 nm have been studied using a photomultiplier - Lanthanum Bromide detector setup with a PuBe neutron source. The raw data from the detectors was analysed by imposing a detector coincidence condition. READ MORE
