Recently it has been demonstrated that plastic scintillators have the ability to distinguish neutrons from gamma rays by way of pulse shape discrimination (PSD). This discovery has lead to new materials and new capabilities. Here we report our work w

Large, 10 cm-size, single crystals of trans- stilbene were grown for the first time from solution by a temperature reduction technique. Their scintillation performance for fast neutron detection depended on the purity of the initial starting material

The primary objective of this project was to better understand the time-correlations between the muons and neutrons produced as a result of high energy primary cosmic ray particles hitting the atmosphere, and investigate whether these time correlatio

Our group at Livermore Lab specializes in nuclear materials measurements and assessments. We have built detectors that we have taken from breadboard to fieldable. We have even commercialized some detectors for rugged non-expert use, such as the Fissi
