چکیده
The polystyrene based scintillator SCSN38, pure polystyrene and pure polymethyl-methacrylate have been irradiated with a beam of fast neutrons and with reactor neutrons. The radiation induced permanent optical absorption coeecients after total annealing in air are compared with data for irradiations. The strong diierences might be due to the high LET of the recoil protons elastically scattered by the neutrons .

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...
متن کاملPlastic gamma sensors: an application in detection of radioisotopes
A brief survey of plastic scintillators for various radiation measurement applications is presented here. The utility of plastic scintillators for practical applications such as gamma radiation monitoring, real-time radioisotope detection and screening is evaluated in laboratory and field measurements. This study also reports results of Monte Carlo-type predictive responses of common plastic sc...
متن کاملCalibration of time of flight detectors using laser-driven neutron source.
Calibration of three scintillators (EJ232Q, BC422Q, and EJ410) in a time-of-flight arrangement using a laser drive-neutron source is presented. The three plastic scintillator detectors were calibrated with gamma insensitive bubble detector spectrometers, which were absolutely calibrated over a wide range of neutron energies ranging from sub-MeV to 20 MeV. A typical set of data obtained simultan...
متن کاملMeasurement of Fission Neutron Spectrum and Multiplicity using a Gamma Tag Double Time-of-flight Setup
Recent efforts have been made to improve the prompt fission neutron spectrum and nu-bar measurements for Uranium and Plutonium isotopes particularly in the keV region. A system has been designed at Rensselaer Polytechnic Institute (RPI) utilizing an array of EJ-301 liquid scintillators as well as lithium glass and plastic scintillators to experimentally determine these values. An array of BaF2 ...
