Latest Patents

Among his most notable patents is the "Accurate Light-Weight Broad-Energy Neutron Remmeter and Use Thereof." This innovative remmeter employs multiple different-sized hydrogenous moderators, each containing fast neutron and thermal neutron detectors. His design allows for more precise neutron dosimetry across a broad range of neutron energies, from thermal neutrons to over 15 MeV, all within a lighter form factor compared to conventional remmeters. By utilizing spectral dosimetry principles, Andrews enhances accuracy by measuring energy distributions of incident neutrons, thus mitigating variations in response from various fluence-to-dose conversion curves.

Another significant invention is the "Gas Avalanche Neutron Detector" (GAND), which provides a cutting-edge alternative for detecting thermal neutrons or neutron radiation without relying on traditional proportional counters. The GAND incorporates a thermalization layer and utilizes Boron-10 for neutron capture, generating alpha particles that ionize the detector's gas. This process not only produces ionization electrons but also amplifies the signal, greatly increasing sensitivity in neutron detection.
