Spectroscopic neutron detection using composite scintillators

Monte Carlo Models of Neutron Detection with Organic Scintillators

We describe the use of the MCNP-PoliMi code to simulate, on an event-by-event basis, the detection of neutrons by organic scintillators. This code keeps track of single neutron interactions, including the collision nucleus, the energy deposited, and the time distribution of collision events. We show that the total pulse-height response is given by the sum of many possible neutron histories, eac...

First Tests of 6Li Doped Glass Scintillators for Ultracold Neutron Detection

We report the results of test measurements aimed at determining the performances of (6)Li doped glass scintillators for the detection of ultra-cold neutrons. Four types of scintillators, GS1, GS3, GS10 and GS20, which differ by their (6)Li concentrations, have been tested. The signal to background separation is fully acceptable. The relative detection efficiencies have been determined as a func...

Accepted for Publication in Nimb Neutron Irradiated Plastic Scintillators

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 ...
