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

Calculation of the Pulse Height Distribution Induced by Fast Neutrons in a Scintillation Detector

The probability distribution of light pulses produced in an organic scintillator by impinging fast neutrons is calculated. It is assumed that the slowing down takes place on a mixture of hydrogen and carbon atoms, and that the light produced is a non-linear function of the energy transferred to the H atoms and a linear function of the transferred energy to C atoms in each individual collision. ...

Measurements of Scintillation Efficiency and Pulse-Shape for Low Energy Recoils in Liquid Xenon

Results of observations of low energy nuclear and electron recoil events in liquid xenon scintillator detectors are given. The relative scintillation efficiency for nuclear recoils is 0.22 ± 0.01 in the recoil energy range 40 keV 70 keV. Under the assumption of a single dominant decay component to the scintillation pulse-shape the log-normal mean parameter T0 of the maximum likelihood estimator...

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...

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...
