Monte Carlo N-Particle simulations of an underwater chemical threats detection system using neutron activation analysis
P. Sibczyński, M. Silarski, O. Bezshyyko +7
In this paper we present Monte Carlo N-Particle (MCNP) simulations of the system for underwater threat detection using neutron activation analysis developed in the SABAT project. T…
Feasibility study of the time reversal symmetry tests in decays of metastable positronium atoms with the J-PET detector
A. Gajos, C. Curceanu, E. Czerwiński +29
This article reports on the feasibility of testing of the symmetry under reversal in time in a purely leptonic system constituted by positronium atoms using the J-PET detector. The…
Towards 2+1 photon tomography: Energy-based selection of two 511 keV photons and a prompt photon with the J-PET scanner
R. Masełek, W. Krzemien, K. Klimaszewski +31
The possibility to separate signals caused by 511 keV photons created in annihilation of electron-positron pairs and the so-called prompt photons from nuclei de- excitation is inve…
Underwater detection of dangerous substances: status the SABAT project
M. Silarski, P. Sibczyński, Sz. Niedźwiecki +3
The Neutron Activation Analysis (NAA) plays an exceptional role in the modern nuclear engineering, especially in detection of hazardous substances. However, in the aquatic environm…
Commissioning of the J-PET detector for studies of decays of positronium atoms
E. Czerwiński, K. Dulski, P. Białas +29
The Jagiellonian Positron Emission Tomograph (J-PET) is a detector for medical imaging of the whole human body as well as for physics studies involving detection of electron-positr…
Introduction of total variation regularization into filtered backprojection algorithm
L. Raczyński, W. Wiślicki, K. Klimaszewski +30
In this paper we extend the state-of-the-art filtered backprojection (FBP) method with application of the concept of Total Variation regularization. We compare the performance of t…
