Thermal neutron imaging in the local lab

We have started an effort to bring the benefits of neutron radiography to the local laboratory. We have started imaging experiments with a fusion neutron generator as a source. A generator is a commercially available, compact neutron source. With a flux that is orders of magnitude weaker than a reactor, ingenuity is required to make good-quality images. The sensitivity of the detector is of vital importance. We have developed the most sensitive neutron imaging detector on the market, based on our patented neutron-sensitive microchannel plates. We will show the principles and design of the detector and demonstrate some results. We reveal the first imaging results using our DD fusion generator as a source, proving the feasibility of this type of instrument. And we outline our plans and ambitions for the immediate future. This development will democratize access to neutron imaging and make it available to the non-destructive testing community.

Abstract

We have started an effort to bring the benefits of neutron radiography to the local laboratory. We have started imaging experiments with a fusion neutron generator as a source. A generator is a commercially available, compact neutron source. With a flux that is orders of magnitude weaker than a reactor, ingenuity is required to make good-quality images. The sensitivity of the detector is of vital importance. We have developed the most sensitive neutron imaging detector on the market, based on our patented neutron-sensitive microchannel plates. We will show the principles and design of the detector and demonstrate some results. We reveal the first imaging results using our DD fusion generator as a source, proving the feasibility of this type of instrument. And we outline our plans and ambitions for the immediate future. This development will democratize access to neutron imaging and make it available to the non-destructive testing community.
