Optical properties and pulse shape discrimination in siloxane-based scintillation detectors

Further study of CdWO4 crystal scintillators as detectors for high sensitivity 2β experiments: scintillation properties and pulse-shape discrimination

Energy resolution, light yield, non-proportionality in the scintillation response, α/β ratio, pulse shape for γ rays and α particles were studied with CdWO4 crystal scintillators. Some indication for a difference in the emission spectra for γ rays and α particles was observed. No dependence of CdWO4 pulse shape on emission spectrum wavelengths under laser, α particles and γ ray excitation was o...

Tomographic Analysis of Neutron and Gamma Pulse Shape Distributions from Liquid Scintillation Detectors at JET

Scintillation Pulse Shape Discrimination in a Two-Phase Xenon Time Projection Chamber

The energy and electric field dependence of pulse shape discrimination in liquid xenon have been measured in a 10 gm two-phase xenon time projection chamber. We have demonstrated the use of the pulse shape and charge-to-light ratio simultaneously to obtain a leakage below that achievable by either discriminant alone. A Monte Carlo is used to show that the dominant fluctuation in the pulse shape...

Light Output and Pulse Shape Properties of Cryogenic Nai Scintillation Crystals for Dark Matter Searches

Results of tests on NaI scintillation crystals operated at cryogenic temperatures are described. Crystals grown using both the Bridgeman-Stockbarger and Czochralski techniques were tested. Light output and scintillation pulse shape properties are assessed as functions of temperature using gamma and 252 Cf neutron sources and the results are interpreted with a view to optimising detector perform...

Tomographic analysis of neutron and gamma pulse shape distributions from liquid scintillation detectors at Joint European Torus.

The Joint European Torus (JET, Culham, UK) is the largest tokamak in the world devoted to nuclear fusion experiments of magnetic confined Deuterium (D)/Deuterium-Tritium (DT) plasmas. Neutrons produced in these plasmas are measured using various types of neutron detectors and spectrometers. Two of these instruments on JET make use of organic liquid scintillator detectors. The neutron emission p...
