Measuring Carbon-in-soil Distribution using an Associate Particle Imaging System

Measuring Carbon-in-soil Distribution using an Associate
Particle Imaging System
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, gamma
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.
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.
