Nanoparticles-loaded plastic scintillators for fast/thermal neutrons/gamma discrimination: Simulation and results

Optical simulation and experimental measurement of gamma ray energy spectrum of plastic scintillators with different sizes

The application of large plastic scintillators is widely increasing in the different areas of industry, medicine and security due to technical and economic advantages. One of the main disadvantages of these detectors is the unknown position of Compton edge at gamma ray spectrum. In this research, GEANT4/GATE code has been used to simulate the gamma ray spectrum for different volumes of large pl...

Temperature dependence of plastic scintillators

Plastic scintillator detectors have been studied as dosimeters, since they provide a cost-effective alternative to conventional ionization chambers. On the other hand, several articles have reported undesired response dependencies on beam energy and temperature, which enhances the necessity to determine appropriate correction factors. In this work, we studied the light yield temperature depende...

Metal-loaded organic scintillators for neutrino physics

Organic liquid scintillators are used in many neutrino physics experiments of the past and present. In particular for low energy neutrinos when realtime and energy information are required, liquid scintillators have several advantages compared to other technologies. In many cases the organic liquid needs to be loaded with metal to enhance the neutrino signal over background events. Several meta...

PULSE SHAPE DISCRIMINATION CHARACTERISTICS OF STILBENE CRYSTAL, EJ-299-33 AND Li LOADED PLASTIC SCINTILLATORS FOR A HIGH RESOLUTION CODED-APERTURE NEUTRON IMAGER

Pulse shape discrimination performances of single stilbene crystal, EJ-299-33 plastic and Li loaded plastic scintillators have been compared. Pulse Gradient Analysis pulse shape discrimination algorithm has been tested for each scintillator sample, assessing their neutron/gamma separation. In this study each scintillator sample was irradiated with a Cf neutron source and, a real-time fast digit...
