Abstract:
Associated Particle Imaging (API) is a nuclear technique that allows for the nondestructive determination of 3D isotopic distributions. The technique is based on the detection of the alpha particles associated with the neutron emitted in the deuterium-tritium (DT) fusion reaction, which provides information regarding the direction and time of the emitted 14 MeV neutron. Inelastic neutron scattering leads to characteristic gamma-ray emission from certain isotopes, for example 12 C, that can be correlated with the neutron interaction location. An API system consisting of a sealed-type neutron generator, amma
detectors, and a position-sensitive alpha detector is under development for the nondestructive quantification of carbon distribution in soils. The talk will give an overview of the project.
About the Speaker:
Arun Persaud is a Staff Scientist in the Accelerator Technology and Applied Physics Division (ATAP) at Lawrence Berkeley National Laboratory (LBL). He studied Physics in Darmstadt, Germany and worked for his PhD at LBL on a quantum computer project where his research was focused on building tools for single ion implantation. He received his PhD in 2007 from the University of Frankfurt, Germany. After a Postdoc at LBL he became a Staff Scientist and works now mostly on ion accelerators as well as neutron generators and gamma detectors.
