Description
We present novel thermal and fast neutron detector technologies that have been created at QMUL in collaboration with our industrial partners, AWE and Micron Semiconductor Ltd. These technologies enable the creation of large area thermal and fast neutron detector solutions using organic and inorganic semiconductors. We have demonstrated the ability to detect neutrons over the range of energies from 0.025eV to 16.5MeV with organic semiconductor technology. Our inorganic semiconductor technology enables us to detect fast neutrons with a low photon background contamination, as well as having an enriched boron coating that enables the measurement of thermal neutrons. Simulation has played an important role in the design of these technologies, and also in helping us establish the QMUL Neutron facility. Signals from the organic and inorganic sensors can be acquired and analysed to disambiguate between the fast and thermal neutron components in the data.
