Neutrons are/can be used in several applications such as material science, medical science, non-destructive investigation, security, neutron radiography and maintenance of social infrastructures such as bridge and tunnel. To detect the fast neutrons, gaseous detectors (3He, 10B) and neutron scintillators (H, 6Li, 10B) can be used in such fields....
Three Polyvinyltoluene (PVT) scintillators, provided by Lawrence Livermore National Laboratory (LLNL), with different dimensions and doped with 2% Flrpic (an Iridium complex flour) have been characterized in terms of spatial resolution and relative light output using the North Radiography Station (NRS) beamline of Neutron Radiography (NRAD) Reactor at the Idaho National Laboratory (INL). The...
Experiments conducted at Idaho National Laboratory (INL) measured the performance of prototype fast neutron scintillator screens with various scintillator materials deposited in a range of thicknesses on high density polyethylene (HDPE) of varying thickness. The HDPE acts as a converter for the fast neutrons, utilizing a proton recoil reaction to cause the scintillator material to emit...
