Latest Patents

Among his latest innovations, Allen developed an explosives detector that features an apparatus designed for non-invasively inspecting items, such as luggage, for explosive materials. This system includes a multi-channel thermal neutron inspection system with several neutron irradiation chambers, allowing for simultaneous operation that significantly boosts the maximum throughput of the system. Each chamber utilizes a lithium neutron source stimulated by a proton beam, ensuring low residual source activity and controlled neutron production, thereby minimizing safety hazards. Furthermore, the irradiation chamber incorporates multiple gamma ray detectors to identify elements prevalent in explosive materials. Additionally, a neutron radiography imaging function can help in detecting potential shielding materials.

In another groundbreaking invention, Allen's non-invasive inspection method employs positron emission tomography (PET) to detect residual core material inside hollow cast articles. This method involves immersing a cast article in an aqueous solution containing radio-isotope emitters, such as gallium. The emitted positrons interact with electrons producing gamma rays, which are detected and analyzed by a PET camera. This innovative approach can reveal the location of core materials, first using a low-dose-rate solution and then a more active solution for detailed imaging.
