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 ...
Influence of the water content in rock on the thermal neutron diffusion and diffusion cooling coefficients (by Monte Carlo simulations). II: – Quartz

Drozdowicz, Krzysztof; Krynicka, Ewa; Dąbrowska, Joanna (Institute of Nuclear Physics Polish Academy of Sciences, 2003)

The dependence of the thermal neutron diffusion parameters on the water content w in quartz, SiO2, has been studied by means of Monte Carlo simulations of the pulsed neutron experiments for a number of series of samples. ...
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 ...
Monte Carlo simulations of the pulsed thermal neutron flux in two-region hydrogenous systems (using standard MCNP data libraries)

Wiącek, Urszula; Krynicka, Ewa (Institute of Nuclear Physics Polish Academy of Sciences, 2005)

Monte Carlo simulations of the pulsed neutron experiment in two- region systems (two concentric spheres and two coaxial finite cylinders) are presented. The MCNP code is used. Aqueous solutions of H3BO3 or KCl are used ...
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 ...
