  • Assumptions for the design of a neutron pinhole camera dedicated to the PF-24 device 
    Scholz, Marek; Bielecki, Jakub; Wójcik-Gargula, Anna; Wiącek, Urszula; Drozdowicz, Krzysztof; Igielski, Andrzej; Kulińska, Agnieszka; Tracz, Grzegorz; Woźnicka, Urszula (Institute of Nuclear Physics Polish Academy of Sciences, 2014)
    The report presents main assumptions on the design of the neutron pinhole camera dedicated to the PF-24 (Plasma Focus) device. The pinhole camera will be used for the investigation of the spatial and temporal distributions ...
  • Feasibility study of experimental detection of the hydrogen content in rock material by a pulsed neutron method 
    Drozdowicz, Krzysztof; Drabina, Andrzej; Dąbrowska, Joanna; Gabańska, Barbara; Igielski, Andrzej; Janik, Władysław; Krynicka, Ewa; Kurowski, Arkadiusz; Wiącek, Urszula; Woźnicka, Urszula (Institute of Nuclear Physics Polish Academy of Sciences, 2003)
    Theoretical principles of a pulsed neutron method to measure the water or hydrogen content in a rock material have been tested on the experimental set-up at the fast neutron generator in the INP. The time decay constant ...
  • Measurements of the effective thermal neutron absorption cross-section in multi-grain model 
    Drozdowicz, Krzysztof; Gabańska, Barbara; Igielski, Andrzej; Krynicka, Ewa; Schneider, Krystyna; Woźnicka, Urszula (Institute of Nuclear Physics Polish Academy of Sciences, 2005)
    The effective macroscopic absorption cross-section Σaeff of thermal neutrons in a grained medium differs from the corresponding cross-section Σahom in the homogeneous medium consisting of the same components, contributing ...
  • Physical assumptions for a design of the DET-12 chamber for detection of delayed neutrons 
    Bieńkowska, Barbara; Drozdowicz, Krzysztof; Gabańska, Barbara; Igielski, Andrzej; Prokopowicz, Rafał; Wiącek, Urszula; Woźnicka, Urszula (Institute of Nuclear Physics Polish Academy of Sciences, 2014)
    Physical assumptions have been outlined to design a new device (DET-12) for measurements of delayed neutron emitted from samples of fissionable materials activated with neutrons at big fusion-plasma devices. The aim is to ...
  • Preliminary test of the scintillator with optical fiber (SOF) detector in a pulsed thermal neutron experiment 
    Igielski, Andrzej; Janik, Władysław; Kurowski, Arkadiusz (Institute of Nuclear Physics Polish Academy of Sciences, 2006)
    A scintillator with an optical fiber detector (SOF) consists of a small amount of the ZnS(Ag) scintillator mixed with a transparent adhesive material and a thermal neutron converter (6LiF). It is tightly connected to the ...
  • Principles of a method to use CVD diamond detectors for spectrometric measurements of particles in mixed radiation field emitted by D-D and D-T fusion plasmas 
    Drozdowicz, Krzysztof; Dankowski, Jan; Igielski, Andrzej; Jaskóła, Marcin; Korman, Andrzej; Kurowski, Arkadiusz; Marczewska, Barbara; Nowak, Tomasz; Wiącek, Urszula; Woźnicka, Urszula; Gabańska, Barbara (Institute of Nuclear Physics Polish Academy of Sciences, 2014)
    Future thermonuclear reactors for needs of power plants will operate with the deuterium-tritium fuel. Neutron, alpha particle, and energy are created in the fusion reaction between these isotopes. Measurement of energy of ...
  • Sensitivity of the Thermal Neutron Time Decay to the Hydrogen Content in a Rock Sample 
    Drozdowicz, Krzysztof; Dąbrowska, Joanna; Gabańska, Barbara; Igielski, Andrzej; Janik, Władysław; Krynicka, Ewa; Kurowski, Arkadiusz; Niedźwiedź, K.; Wiącek, Urszula; Woźnicka, Urszula (Institute of Nuclear Physics Polish Academy of Sciences, 2004)
    A pulsed neutron method to measure the water or hydrogen content in a rock material has been tested on the experimental set-up at the fast neutron generator in the IFJ PAN. A dedicated pulsed thermal neutron source has ...
